Article Synopsis
- Radiotherapy processes are prone to errors involving staff and equipment, but Cone-beam CT (CBCT) allows for final checks and corrections before treatment.
- Statistical Process Control (SPC) techniques, commonly used in various industries, were applied to CBCT results in a study of Head and Neck patient treatments over 12 years, demonstrating sensitivity to changes.
- The study found a reduction in random patient setup errors, but systematic errors remained stable, while an increase in errors correlated with the COVID-19 pandemic, and challenges in using SPC for retrospective data analysis were discussed.
