System and method for vascular border detection

In order to use the frequency spectrum of the radio frequency (RF) signal back-scattered from the organization of a blood vessel in order to identify at least one boundaries (for example, organizational boundary etc. ) on the image of a blood vessel, a system and a method are offered. The form of implementation of the present invention operates according to the data collection devices (for example, intravascular supersonic method (IVUS) equipment etc. ) electrically connected with computing equipment via the catheter at the transducer. A transducer is used in order to collect the radio frequency (RF) data back-scattered from the organization of a blood vessel. Next, computing equipment is provided with RF data via a data collection device (or acquired by computing equipment). At least one pieces of the data storing equipment (for example, a database, a memory, etc. ) which stores the parameter relevant to the type of the organization of (1) plurality, and them in computing equipment with the form of one implementation of the present invention, and (2) -- at least one application is included.
