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.

A computer-implemented method for determining an estimate of radiation dose absorbed by an individual in receiving an imaging scan, the method comprising:
- receiving a set of parameters describing the imaging scan and an image scanning apparatus being used to perform the imaging scan;
- receiving a deformed imaging phantom corresponding to the individual;
- evaluating a plurality of previously completed simulations each estimating radiation dose absorption, wherein the plurality of previously completed simulations are selected from a simulation library;
- and
- 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.
A non-transitory computer-readable storage medium comprising computer-readable code that, when executed by a processor, performs an operation for determining an estimate of radiation dose absorbed by an individual in receiving an imaging scan, the operation comprising:
- receiving a set of parameters describing the imaging scan and an image scanning apparatus being used to perform the imaging scan;
- receiving a deformed imaging phantom corresponding to the individual;
- evaluating a plurality of previously completed simulations each estimating radiation dose absorption, wherein the plurality of previously completed simulations are selected from a simulation library;
- and
- 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,
