Real‐time motion tracking of a gold implant in water by Cherenkov lights
Abstract Background The intra‐fraction motion of tumors during radiation therapy can be monitored using imaging systems based on X‐ray imaging (e.g., kV/MV radiography or CBCT) or magnetic resonance imaging (MRI). However, these techniques have limitations, including additional ionizing radiation dose and the need for complex, expensive equipment ...

Multi‐TPS institutional surveillance of VMAT plan complexity and PSQA results over three years
Abstract Background Running VMAT plan‐complexity surveillance directly inside an oncology information system (OIS) makes it practical to monitor plan quality across a large, multi‐linac program. Complexity metrics are increasingly used to anticipate patient‐specific QA (PSQA) outcomes, but few studies span multiple years or tie complexity monitoring to

Abstract Background Computerized radiotherapy chart checking tools have revolutionized the initial physics chart review process as they offer verification of large amounts of plan parameters in seconds and allow physicists to concentrate on high‐skill‐level items that are challenging for automation.

Abstract Purpose Spatially fractionated radiation therapy (SFRT) planning requires three coordinated tasks: generation of high‐dose sphere structures, position‐aware optimization, and peak‐valley dose ratio evaluation. In practice, clinicians and researchers address these tasks with a combination of closed‐source scripts, research codes, and manual ...

Abstract BackgroundWhile positioning errors during radiotherapy are increasingly well‐characterized and accounted for in the Planning Target Volume (PTV), little is known about the shape and volume changes of the breast in the course of radiotherapy. Yet they represent an unknown factor that may impact treatment effectiveness, highlighting the need to ...
