Generating an estimate of patient radiation dose resulting from medical imaging scans

Abstract

A non-transient computer-readable storage medium that stores one or more application programs that, when executed by a processor, performs an operation to provide a plurality of imaging providers with estimates of radiation dose absorbed by receiving individuals. imaging scans, comprising the operation: receive, from one of the medical imaging providers, a request for an estimate of the radiation dose absorbed by a particular patient upon receiving an imaging scan, wherein the application includes a set of parameters describing the imaging scan and an image scanning apparatus used to perform the imaging scan and one of a deformed mathematical phantom based on the patient's body morphology concrete and a transformation that is used to deform an initial mathematical phantom into the deformed mathematical phantom in which the deformed mathematical phantom is determined by a procedure that It includes: selecting an initial mathematical phantom for the particular patient receiving an imaging scan, the selection being based on the age and gender of the particular patient; receive one or more scan images of the particular patient; selecting from the images obtained from multiple individuals a reference set of locator images having a body geometry, size and placement that closely matches the initial mathematical phantom; determining a transformation between at least one of the locator images and at least one of the scan images of the particular patient; and deforming the initial mathematical phantom as a function of the transformation by which the deformed mathematical phantom resulting from the transformation better matches the size, shape and organ positions of the particular patient; access resources that comprise a plurality of previously completed ones corresponding to one or more individuals, each of the previously completed simulations having information in these that comprise a previous set of parameters that describe a previous imaging scan and a scanning apparatus used to perform the pre-imaging scan, a prior estimate of radiation dose absorbed by one of the one or more individuals upon receiving the prior imaging scan and a deformed phantom used in calculating the prior estimate of radiation dose associated therewith; evaluating the plurality of simulations previously completed within the resources by comparing the information in them with the set of parameters and the deformed mathematical phantom obtained as a result of the request; after determining, based on the evaluation, that two or more of the previously completed simulations have the information in them that matches within a specified tolerance measurement the set of parameters and the deformed mathematical phantom obtained as a result of the request, interpolating the previous radiation dose estimates in the two previously completed simulations to determine the radiation dose estimate absorbed by the particular patient upon receiving the imaging scan; and returning, to the medical imaging provider, the estimate of radiation dose absorbed by the particular patient.
