Beam Data Verification Audit

Errors in beam data collection often cause flawed TPS models and dose computation errors.

IBA Dosimetry offers an independent audit service to verify beam data accuracy.

“Errors and inaccuracies in beam data collection are reported to frequently lead to flawed TPS beam models and thus to systematic TPS dose computation errors. These systematic beam data errors are however difficult to spot and to eliminate.”

_{Kowatsch, M. et.al. (2018). Monte Carlo based Quality Assurance of Base Data for Beam Modeling in Treatment Planning Systems}

The Challenge: Poor commissioning data are a major dosimetric issue and causes errors throughout the treatment chain.

Therefore, international physics associations recommend an independent audit of the beam data by a qualified medical physicist (e.g. AAPM TG-106, AAPM TG-53, ESTRO Booklet 10…).

Expert opinion on the need for Monte Carlo beam data verification

“The quality of our measured beam data is critical to ensure accurate treatment planning and delivery, especially for stereotactic and other precision therapies. Medical physicists are challenged by varying responses from diodes and ion chambers because of the inherent differences between the different detectors. For the absolute confirmation of accuracy of beam data, I believe that Monte Carlo validation is the path forward for verifying small field beam data and has broader implications for verification of data for larger field sizes as well.”

User Experience with Beam Data Verification Audit

“I have validated our beam commissioning data using the Monte Carlo modeling within SciMoCa. The comprehensive validation report provided guidance to improve the PDD and MLC leaf calibrations in the TPS. We now have the confidence that our beam data is correct and that our treatment plan calculations are of high quality.”
