First Claim
Patent Images
1. A method, comprising:
- segmenting a volume of interest (VOI) from three-dimensional (3D) imaging data to obtain a segmented VOI, wherein the 3D imaging data includes a pathological anatomy; and
generating digitally reconstructed radiographs (DRRs) from 3D transformations of the segmented VOI in each of two or more projections.

45. A system, comprising:
-
a treatment planning system including a first processing device, wherein the first processing device is configured to segment a volume of interest (VOI) from three-dimensional (3D) scan data to obtain a segmented VOI, wherein the 3D imaging data includes a pathological anatomy, and wherein the first processing device is further configured to generate a plurality of digitally reconstructed radiographs (DRRs) from the segmented VOI in each of two or more projections; and a treatment delivery system including a second processing device configured to compare one or more DRRs in each projection with a corresponding two-dimensional (2D) in-treatment image to generate a 2D displacement field in each projection. - View Dependent Claims (46, 47, 48)
