Rapid unpaired CBCT‐based synthetic CT for CBCT‐guided adaptive radiotherapy

Journal of Applied Clinical Medical Physics, 2023
AbstractIn this work, we demonstrate a method for rapid synthesis of high‐quality CT images from unpaired, low‐quality CBCT images, permitting CBCT‐based adaptive radiotherapy. We adapt contrastive unpaired translation (CUT) to be used with medical images and evaluate the results on an institutional pelvic CT dataset.

Joint CT/CBCT deformable registration and CBCT enhancement for cancer radiotherapy [PDF]

Medical Image Analysis, 2013
This paper details an algorithm to simultaneously perform registration of computed tomography (CT) and cone-beam computed (CBCT) images, and image enhancement of CBCT. The algorithm employs a viscous fluid model which naturally incorporates two components: a similarity measure for registration and an intensity correction term for image enhancement ...
