API-enabled integration of Pylinac with QATrack+ for automated EPID-based QA on Elekta linear accelerators: a technical note [PDF]
BACKGROUND: EPID quality assurance (QA) workflows remain largely manual and are difficult to standardise across treatment machines. This limits efficiency, increases operator dependency, and complicates consistent reporting and data sharing between ...

In-vivo dosimetry using electronic portal imaging in online-adaptive radiotherapy for rectal cancer [PDF]
Background and purpose: Electronic portal imaging device (EPID)-based in-vivo dosimetry (IVD) is widely used to verify radiotherapy dose delivery and detect deviations from anatomical changes, setup uncertainties, or machine-related errors. However, cone-

Dose Characteristics of a Deep Learning Model for EPID-based In vivo Dosimetry [PDF]
Background: Images from onboard electronic portal imaging devices (EPID) contain dose information that can be converted into dose maps. A cycle-consistent generative adversarial network (CycleGAN)-based model was developed for two-dimensional (2D) EPID ...

A Validation Method for EPID In Vivo Dosimetry Algorithms [PDF]
The aim of this study was to develop and apply an evaluation method for assessing the accuracy of a novel 3D EPID back-projection algorithm for in vivo dosimetry. The novel algorithm of Dosimetry Check (DC) 5.8 was evaluated. A slab phantom homogeneously filled, or with air and bone inserts, was used for fluence reconstruction of different squared ...
