Abstract
Systems and methods are disclosed for processing of cone beam computed tomography (CBCT) image data, in connection with radiotherapy planning and treatments. Example operations for a radiotherapy workflow include: obtaining a plurality of newly captured CBCT projections that provide imaging of an anatomical area corresponding to an area for radiotherapy treatment; reconstructing a quantitative CBCT image from the plurality of newly captured CBCT projections; identifying anatomical changes of the human patient based on comparing a representation of the anatomical area in the quantitative CBCT image with a representation of the anatomical area in a planning image; and modifying a treatment plan for a radiotherapy workflow based on the anatomical changes, with the treatment plan providing dose calculations for the anatomical area. Further operations for training and use of a regression model to correct CBCT projections and perform additional imaging and radiotherapy data processing operations are disclosed.
