Picture managing system in hospital

[Detailed Description of the Invention]

[Objects of the Invention] (Field of the Invention) The present invention relates to the data management system installed in a hospital. (PRIOR ART) x11A film drawing & and X -CT (Coa+puter Tomography) picture, An I'4RI (MagnetiCRe5onance In+aging) picture and RI (Radio I 5otope) a picture and OR (Couuted Radio graphy) picture. U S It collects, and (U 1tra 5ound) a picture, a family celebration l1ii image, a thermography picture, etc. save all the pictures which occur at the medical spot, and search and display them zero times, and the needs of adding and transmitting 1 image processing are growing rapidly. P 1cture for the university hospitals represented with the experiment of digital image transmission systems [ in / in this trend / the Kansas university ], etc. A rchivinQ &Co++ueunication System (PAC8 is called hereafter.) from -- an end is left -- it is carrying out. Digital image data volume which will occur here on the 1st is made into abbreviation aoovsyte, and it is L ocal of 10 M bit/sec. Although it was what refers to A ria N etwork (LAN is called hereafter.), It leaves a subject called transmission efficiency UP of a picture, and is in the state where the subject of research was handed over to other universities. The actual present condition is that these outlooks began to brighten at last recently about themes, such as transmission of a picture, propriety of CRT diagnosis, arrangement of mass data, and a grope. It has left the problem of whether in the method of the database of Towing, a distributed database is used in such the present condition, or to use a concentration central file. As a typical thing of a distributed database, the system which can make initial introduction expenses cheap is considered by carrying out picture management on a minicomputer or a microcomputer level by connecting an image memory to each modality. However, for example, when the X ray film picture was taken for the example and it assumes that it digitizes 11 degrees of 10.24 steps (10 A bits) by the image data (5MBVte) of resolution by 2000x2000 matrix, it becomes a vast quantity of data m called 50 B yte in the number of films in 1000 sheets. This becomes about 1000 picture generating number of sheets per day of xm film picture, and cannot say even the drawing m management over several months that realization is possible easily in the hospital of 500 floors. On the other hand, a concentration central file method carries out package management of the image data at one place of a hospital, and although initial introduction expenses are large, there is the strong point which copes with extension of a system and the improvement of the quick nature of Navis easily. However, since employment and the terminal of a center are unified and a concentration central file method requires time most by a systems configuration, it is not realization-like. (Problem which an invention tends to solve) use PAC8 generally considered to summarize the above as the fraction type database considered now -- use a concentrated type database -- a problem big [ both ] is held and it can be said that it is lacking in implementability in respect of the introduction to the present hospital. In order to solve the conventional problem, collection and its analysis of the huge data flow of the patient data which flows inside the House about tens of hospitals were conducted, and the data management system based on those results was suggested. The object of the present invention can store several various Oshi's medical picture in a memory, and provides PAC8 in which a systems configuration is possible one by one.

Constitution 1 of [invention (Means for solving a problem) The information transmission means which transmits each patient's j!iii data generated from each modality with the composition in the present invention to the medical-examination unit to which a patient belongs, It has a memory for memorizing the image data from this transmission means, and has a joint means to connect between the image filing device which distributes this memory to each subject and is installed, and the each distributed image filing device. (OPERATION) The fundamental flow in the invention in this application is described, and the reason is indicated. In the results of an investigation performed by the time it resulted in the invention in this application, the total generating data volume which the number of sickbeds generates from each modality in per day in the hospital of 500 floors is about 3.75GBVt8, for example. The modality at this time is targeting the X-ray CT scanner, the MRI apparatus, the ultrasonic device, and the DR device. 3 The data of 750 B yte is divided into data 2.44GByte from an outpatient, and data 1 from an inpatient and 310Byte. If seeing it about an inpatient's data, the image data from modality serves as 0.33GBVtO to a radiation part, and serves as 6.55GByte to the ward. About the outpatient, it has increased very much with 12.20Byte to 0.61 GByte and a consultation room in a similar manner to the Release tlIII section. An outpatient's data flows into the direction of a ward, or an inpatient's data hardly flows into a consultation room. Considering storage of the image data which occurred in each modality, in memorizing the data for five years, it becomes 5740 G B Vte and a vast quantity of data. This will become an optical disc of no less than 1600 sheets, if the storage capacity of one optical disc is set to 3.6GByte. There are very many amounts of image data accessed from this memory storage as an about 20 GBZ day. If the above is summarized, the following thing can mainly be said about the data management in the hospital whose number of sickbeds is about 500 floors. (1) The distributed processing system in which the directory management of data manages an inpatient and an outpatient separately is suitable. (2) The data management needs to attach greater importance than to the data transfer from each modality to a device besides an account to the data transfer from memory storage to a ward or a consultation room further. It is because there is between [ much ] the data in which the total data yield of modality is accessed from memory storage to 3.75 G B yte as 20 G B yte and 5 or more times. This investigation was advanced still more finely and investigation was conducted also about each patient's image data. As a result, between woods which are different although each patient's image data moves frequently within Department to which each patient belongs, it turned out that there is almost no movement of data. The data transfer within Department has closed the rate 90 percent or more of the whole. movement between the woods of the remaining several percent accepts necessity for the sake of convenience of the management top of the time of the patient moving to other departments, or a hospital, or a doctor in charge -- the data transfer between woods -- it carries out. The data transfer rate or quantity between such woods are not required so much compared with it of the data transfer in Department. The present invention constituted in view of the above point is memorized to the image filing device installed in Department to which each patient belongs in the data from each modality, Since it is connected densely, image data transmission to the retrieval device installed in the village from this filing device is performed at high speed, and since it is connected to Rough, image data transmission between woods is performed at a low speed. (EXAMPLE) The 1st example in the present invention is shown in Drawing 4, and is described. In central radiation part 1 of Drawing 4, it has modality called X ray CT Stomach 11 * MRI apparatus 12. ultrasonic diagnostic equipment 13. X-rays Shadow clothing g114. In this central radiation part 1, the signal acquired from an outpatient or an inpatient is changed into image data within each modality, and it is sent out to network 4. Image filing device 22.32 is also connected to network 4 besides modality. And the picture which occurred in each modality is sent to image filing device one f22.32 via this Network and - Ri 4. At this time, each patient's image data is controlled to be transmitted to the image filing device installed in Department to which the doctor in charge of each patient belongs. This control is performed by NIU45. Image filing device 22 and retrieval device 23 are installed in filing room 21 of the 1st internal medicine ward 2. The image data of the patient who is in image filing device 22 in the outpatient whom the doctor of the 1st internal medicine takes charge of, or sickroom 24.25 is sent through a network. Image filing device 22 and Search equipment r1! It is connected closely and 23 can read the patient image data within the same family from retrieval device 23 at high speed. The doctor of the 2nd internal medicine is processed for a patient with Acceptance like [ ward / 3 / 2nd internal medicine ] the 1st internal medicine ward 2. Thus, systematic management of the picture not only about a storage place not being distributed by the kind of picture by managing according to Department in the hospital where the department of a part was carried out but the same patient is made easy to perform. There is much data managed by one more Department, for example, an optical disc is removed from an autochanger, and in placing and managing on a shelf, if the nurse or information manager of the Department moves an optical disc from a shelf to auto Chienneshire, it will end. When moving an optical disc to an autochanger, it is a time of the old case after several years pass coming to a hospital, and troublesome work occurs. However, it cannot be said that there is so much the frequency considering the whole rate. In the concentration central file method by the former, a concentration central file room must be connected with from a patient receptionist by visit to the hospital of above reincarnation Chin. The tendency becomes strong, so that it becomes a large hospital, since it is a constitution in which a patient and image data are especially managed according to Department in a hospital. It becomes desirable to manage image data according to Department for that purpose. In the distributed processing according to modality by the former, in order that the same patient's image data may attain to a plurality of modality, data management is complicated further. Therefore, if the image data managerial system of composition like the present invention is used, it will excel in the extensibility of a system, and pliability besides the above-mentioned advantage, and Ditch building of a system will become easy. Therefore, since it imposes for 2 minutes, and it suits and a system can be easily introduced by Division unit from a small hospital also in the comparatively big hospital not only under the number of sickbeds being able to cover even the big hospital of 1200 or more floors but present management, in almost all hospitals, style * Construction of a system becomes possible one by one. It is connected [ both ] by network 5, and each marginal filing device 22.32 of both can deliver and receive [ both ] data. It is such and also the frequency of the data transfer to a department is very small compared with the village. Therefore, the network between woods is connected to Rough rather than the transmission in Department. A subject file and a retrieval device are combined densely (this is hereafter called the communication in Department.), and there is the method of showing between woods below as a means combined with Rough (this is hereafter called the communication in Department.). (A) Send the data communications on the network of the communication in Department rather than the communication in Department at high speed. for example, -- sending with the data transfer rate of 20Mbyt/a second through an optical fiber in the communication in Department -- the department question communication of one side -- a coaxial cable -- the data communications of 0.5MbVt / second -- it carries out. (B) Combine the communication in Department, and the communication in Department in the network, make a transmission rate the same, and lower and carry out data transfer of the priority of the communication in Department. (C) When transmitting data from other departments, provide beforehand the protocol which obtains a partner's permission, or the work which adds the input input of a keyword in each retrieval device 23.33. Time until the image data in other departments is obtained from a search start by this becomes long substantially. (D) A repeater or a gateway is added to the network of the communication in Department, it combines with it, and the information between woods is performed through a repeater or a gateway. (A) thru/or (D) are above few (if it carries out by using any they are, the data communications between woods can be performed, without causing trouble also in the frequent search by the communication in Department.). Since it begins to search search time with a retrieval device in the present invention, time until the searched picture is displayed is said. next, the 2nd example of the present invention -- the 1st -- incidentally it is shown and explains. In 1st [ The ] figure central radiation part 6, it has X ray CT Wear @61 *62, MRI apparatus63Ultrasonic diagnosisfiR64, 65*66, NM device 67, and X$il Aki device 68. endoscope apparatus 69. These are installed in a plurality of A room, detect and carry out imaging of the signal from an inpatient or an outpatient, and are outputted as image data. In modality 61 and 62.63, it is DC (abbreviation >611.621 *631 of D ata c ompression is connected.) respectively. DC device carries out the data compression of the image data from modality, and outputs it to NIU(abbreviation of N etwork I nterface IJ nit)42. On the other hand, since ultrasonic diagnostic equipment 64.65.66 has the the same data output format, the data compression has been substituted for one DC device 651. And the output from DC651 is temporarily memorized by (M agnetic[) M D isc661, and it waits for it until the network connected to an output is opened wide. Thereby, a collision in a network is avoidable. Since other modality 61.62.63 equips the inside with the memory, it does not need MD specially. The network system connected to central radiation part 6 has optical fiber 411 for connecting between NIU42.43.44.45, SC (abbreviation of S tar Coupler)41, and 5 C-N ILJ, and is constituted in the shape of a star. And the image data compressed from NrU42.43.44 by the side of modality is transmitted to NIU45 installed in the picture Jujuy ring side via optical fiber 411 and 5C41. NIU42.43.44 has the work which changes the data of a large number from modality into light, and sends it out. NIU45 changes a lightwave signal into an electric signal, and it also performs network control. Control is efficiently performed so that the signal from every NIU42.43.44 may not collide. 7 shown in Drawing 1 and 8.9 are Department in one hospital by which the department of a part was carried out (for example, according to specialities), and have become the 1st internal medicine, the 2nd internal medicine, and the 1st surgery, respectively. The field of medicine other than these, for example, the obstetrics, pediatrics. Since ophthalmology is the almost same composition as the 1st internal medicine fundamentally, it has been omitted. Even if this one unit does not necessarily persist in Department, and summarizes closely related Department to one and is unrelated, it is possible to collect into one by making Department with few beds into a medical-examination unit. such a plurality of Department -- each -- Emergence -- it was in the building, or it was divided for every different story, and is collected per each subject. Even if geographically separated from some, it has stuck among doctors. Medical examination'178.88 for an image filing device 71*81 and medical office 76.86. ward 77.87. visitor is installed in each subject 7.8. And image filing device 71.81. medical office 76*86 of each subject and consultation room 78.88 for a ward 77.87. visitor are closely combined via NIu74.79 and 84*89 by the network system for which each used Star Cubra 75.85. The image data from each modality is transmitted through the picture filing Wear W171.81*91 Henet work system of Department with which the patient belongs. The memory (for example, optical disc) in which abbreviation 72 of TMD isc (Temporary Magnetic [) which equipped image filing device 71 with the memory (for example, a magnetic disk and RAM) in which re-writing is possible, and re-writing are impossible It has ODL73 (abbreviation of Optical Disc Libray) which it had. In 0DL73, it has a shelf which keeps the optical disc which cannot be stored in the autochanger which is not illustrated and an autochanger. Both are connected and TMD72 and 0DL73 are connected also to NIU74. - It is carried out. TMD72 is respectively distributed by the patient by the image data for hospitalization, and the image data for a visitor. And ward 77 passes through the image data for hospitalization VC70, and the image data for a visitor is mainly sent to vC70 with which consultation room 78 was equipped. dividing management of a graphics file into the object for hospitalization, and a visitor -- each -- a predetermined place -- Sending -- data flows smoothly by making it like. It is connected also to N1u45 and TMD72 is memorized by the memory via NIU45 in the image data from central radiation part 6. medical office 76, ward 77, and consultation room 78 -- every -- NIU E" To and V C(abbreviation of V iewing Console)7 (When -- the image data which Is provided and a doctor and a patient leaned VC70 and was obtained in central radiation part 6 can be reproduced and seen.) It is like [ for example, it carries out image display of VC''70 ] a monitor. *. vC70 for diagnosis installed especially in the medical office has an image processing device which is not illustrated, carries out image processing (for example, luminosity conversion, addition of S chemer or Rot, expansion 9 emphasis, and formation of Multi-i1agino) of the image data memorized by TMD72, and displays it. Since this Dr. Nyori can see each patient's picture in the optimal state, more exact diagnosis can be carried out. Data communications are independently performed to each subject using 5C75 and 85, respectively, and they are a plurality of N (controlled by NIU74.84 for data not to collide but to transmit U question efficiently moreover.). The data transfer technique in this case is based on Japanese-Patent-Application-No. No. 259633 [ 59 to ] gazette for which it applied on September 7, Showa 59. The art of providing transmission way 752,852.952 only for control data for transmitting efficiently optical fiber 751.851 and the image data only for image data transmission to this gazette, and performing the data communications of NIurai is indicated. Although the network system by the above-mentioned gazette is installed in each subject, it adds to it, repeater 100 is provided, and the network system of each subject is combined. This repeater 100 sends out five Ceach 75, 85, and the data from 95 to other 5C75, 85, and 95. 1jj1100 of this repeater lowers a priority rather than transmission way 751.851 by control transmission line 952 and supervisor 101, and is performed. Repeater 100 is controlled by supervisor 101 to have until it accumulates in A buff 7 memory temporarily and condition of use is canceled, when it has a buffer memory which is not illustrated, the transmission place of data is in condition of use and it cannot transmit, or to direct resending to the destination. Thus, the amount of charges can be communicated, without interfering with the data communications of transmission way 751.851 by combining between networks via a repeater. Next, the flow chart by which To do is shown to Drawing 3 that it may grasp systematically at a sake explains the present invention. The signals from a patient are first collected by modality, and image data is created. It understands whether at this time, the patient is already in the hospital, or to what [ whether it is a visitor and ] Department it belongs. As a method of learning, it can recognize by patient ID and the input data from each modality. The image data from each modality is transmitted to image filing devices 71 and 81.91 of Department with which the patient belongs through a network system. In filing device 71.81.91, it further distributes the object for hospitalization, and for a visitor, and they memorize image data. The image data from NILJ45 is sent into TMD72 *82.92 of Department (the department of one, or the department of plurality) to which the patient belongs, and is indicated to an eraser bull memory. (140) The patient at this time (temporarily referred to as Mr. A) assumes that he is the outpatient who has received medical examination only by the 1st internal medicine. And the eraser bull memory of Ding MD72 which both the data of the tomogram for Mr. A and a photography image is compressed with xmcm binding 61 and X-rays equipment 68 72, and is in the 1st internal medicine 7 memorizes. And the memory is temporarily accumulated in the data area for visitors. By the command by the input from VC70 at medical office 76 or the interpretation-of-radiogram room which is not illustrated, it is read in the eraser bull memory of TMD72, and is immediately sent via NIU74.79. It is restored to a basis and the image data sent to VC70 of medical office 76 from TMD72 is displayed on VC70 as a visible image. (150) Since it has an image processing device in this VCLL profitably, a doctor can edit and see a picture arbitrarily. Mr. A's picture is still memorized by TMD72. When a patient is examined by Takumi of visitors 78, a demand command of picture transmission is given to TMD72 from VC70 in visitors 78. The image data which carried out 11 (between one @ For example) progress from the time of TMD72 memorizing at the time of predetermined, or special events, such as all the ends of an inspection, ended is moved to 0DL73. After being moved, the image data which TMD72 moved is eliminated in order to secure the area where the following image data is memorized. Next, Mr. A must be sent to hospital and suppose that it moved from visitors to the ward. Then, all Mr. A's image data obtained before the time is transmitted to DISK which is attached to VC for diagnosis for wards from 0DL73 and which is not illustrated. At this time, Mr. A's image data is memorized according to a time series by the file for hospitalization in the order acquired by modality. Since [ compared with 0DL73 / that it is / a storage capacity / smaller for data to be memorized by DISK which does not illustrate / above-mentioned ] access time is small, the search time from ■C70 becomes short. Therefore, the image data whose frequency in use of data is comparatively high is memorized to DISK which does not illustrate [ above-mentioned ]. Suppose that Mr. A recovered in ward 77 of the 1st internal medicine 7, and he left hospital. Then, it is moved from the optical disc autochanger in the inside of 0DL73 to an optical disc shelf. (160) This movement may be automatically carried out to a mechanical transportation means, and the management representative of filing device 71 of the 1st internal medicine may perform it manually. movement on such a shelf is restricted only at the time of leaving hospital -- things (carried out also when it goes through the case where a patient dies, an outpatient's full recovery, or II for predetermined (for example, six months).) (170) Although the example of the present invention was described above, the present invention is not limited to the above-mentioned example, can be changed variously and can be used. For example, as shown in Drawing 2, image filing device 71 of each subject, 81*91, and medical office 76.86.96 are also included in radiation part 666. The network used for combination between ■ modality 1 subject one is not limited to the star coupler method by this explanation, either, and other network means may be used. ■ When there are few amounts of communications, it is also possible to make all the networks into the same network. ■ It may be made the file according to not every department but part. Thus, the present invention is variously changed by the structure of each hospital, and the organization.

Effect 1 of [invention According to [ the above ] the present invention, it is a medical picture of various modality about the same patient, It becomes easy to use synthetically and to carry out diagnostic imaging, and it becomes easy to perform systematic management of the picture about one patient, and can make small search time which the whole occupies because the communication in Department makes search time of a medical picture shorter than the amount communication of charges common.
