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.10/11 10005 START RECEIVE IMAGE PHANTOM AND 2013D IMAGE REGISTRATION 1005 TRANSFORM OR 3D VOLUMETRIC DISPLACEMENT FIELD AND PHANTOM VOXELZATION RECEIVE PARAMETERS OF CT SCANNING SYSTEM AND 1010 IMAGING PLAN IDENTIFY TWO (OR MORE) DOSE ESTIMATION SIMULATIONS 1015 MATCHING TRANSFORMED PHANTOM, CT SCANNING SYSTEM AND IMAGING PLAN 1020 YES MATCHING NO SIMULATIONS WITHIN TOLERANCE? 1030 1025 PERFORM MULTIVARIATE INTERPOLATION MARK IMAGE PHANTOM AND USING MATCHING SIMULATIONS TO RECEIVED PARAMETERS FOR ESTIMATE ORGAN ABSORBED DOSE SIMULATION RETURN ESTIMATED DOSE TO REQUESTING SYSTEM 1035 FIG. 10
