Abstract
Techniques are disclosed for estimating patient radiation exposure during computerized tomography (CT) scans. More specifically, embodiments of the invention provide efficient approaches for generating a suitable patient model used to make such an estimate, to approaches for estimating patient dose by interpolating the results of multiple simulations, and to approaches for a service provider to host a dose estimation service made available to multiple CT scan providers.
Claims18
A computer-implemented method for providing a plurality of medical imaging providers with estimates of radiation dose absorbed by individuals receiving imaging scans, the method comprising:
- receiving, from one of the medical imaging providers, a request for an estimate of radiation dose absorbed by an individual in receiving an imaging scan, wherein the request identifies an imaging phantom, a transformation for deforming the imaging phantom, and a set of parameters describing the imaging scan and an image scanning apparatus being used to perform the imaging scan;
- deforming the imaging phantom based on the transformation;
- evaluating a plurality of predetermined dose estimation simulations each estimating radiation dose absorption, wherein the plurality of predetermined dose estimation simulations are selected from a simulation library;
- determining, based on the evaluation, whether to perform a simulation of the imaging scan using the received set of parameters and the deformed imaging phantom to determine the estimate of radiation dose absorbed by the individual, wherein the simulation of the imaging scan, when performed, is stored in the simulation library to thereby increase a probability of identifying, for subsequent imaging scans, suitable previously completed simulations for estimating radiation dose without performing simulations of the subsequent imaging scans;
- and
- returning, to the medical imaging provider, the estimate of radiation dose that is determined based on one of (1) the performed simulation of the imaging scan, and (2) one or more dose estimation simulations of the plurality of predetermined dose estimation simulations.
