Retrospective analysis of machine service logs and EPID-based linac QA to investigate the effects of machine maintenance and calibration events on beam characteristics: A multi-institutional study. [PDF]
J Appl Clin Med PhysAbstract Background Electronic Portal Imaging Devices (EPIDs) are widely used for LINAC quality assurance (QA) and underpin many manufacturer integrated quality control (MIQC) tools, yet the practical impact of routine linac service and calibration events on EPID‐derived beam characteristics remains under‐described. The Automated Quality Assurance (AQA)

Implementation and preliminary evaluation of a practical digital workflow for routine laser-radiation field coincidence quality assurance on the CyberKnife M6. [PDF]
Precis Radiat OncolAn MLC QA tool–QASC–CKQA workflow achieved the lowest laser‐radiation field coincidence deviations on CyberKnife M6, supporting a simpler, more reproducible routine QA strategy. When QASC is unavailable, the film‐based MLC QA tool workflow provides a practical alternative.
