Abstract Background Data-driven gating (DDG) can improve PET quantitation and alleviate many issues with patient motion. However, misregistration between DDG-PET and CT may occur due to the distinct temporal resolutions of PET and CT and can be mitig

Purpose Assessment of image quality directly in clinical image data is an important quality control objective as phantom-based testing does not fully represent image quality across patient variation. Computer algorithms for automatically measuring no

Highlights • ANN prediction models directly compare online, offline, 60Co-, and linac-MRgRT plans. • Roughly one third of 60Co adapted plans deemed inferior to comparable offline plans. • Linac adapted plans essentially equivalent to comparable

Purpose Daily online adaptive plan quality in magnetic resonance imaging guided radiation therapy (MRgRT) is difficult to assess in relation to the fully optimized, high quality plans traditionally established offline. Machine learning prediction mod
