MP-EP03 #105 Statistical Control Process in Tomotherapy pre-treatment QA, Rosa Petit

February 16, 2021

Patient-specific QA using SPC and gamma analysis in helical Tomotherapy™ with ArcCheck™ established tolerance and action limits across anatomical sites (abdomen, head & neck, breast + SVC, prostate). Results showed varied control limits, indicating stable processes in head & neck and prostate treatments compared to challenges in breast + SVC and abdomen due to dose distribution complexities.

Artificial Intelligence and the Future of Medical Physics

Artificial intelligence is beginning to transform radiotherapy and medical imaging. While automation may replace some traditional tasks in medical physics, it will also increase the importance of measurement science, calibration, and quality assurance to guarantee safe and reliable treatments.

Statistical Process Control in Tomotherapy Pre-Treatment QA

September 3, 2024

Patient-specific quality assurance (QA) is a critical step in modern radiotherapy. Using Statistical Process Control (SPC) techniques in helical Tomotherapy allows clinicians to define tolerance and action limits for treatment verification metrics, improving treatment reliability and patient safety.
