Technical note: Absolute dose measurements of a vault‐free radiosurgery system

Abstract: Background Methods for accurate absolute dose (AD) calibration are essential for the proper functioning of radiotherapy treatment machines. Many systems do not conform to TG‐51 calibration standards, and modifications are required. TG‐21 calibration is also a viable methodology for these situations with the appropriate setup, equipment, and factors. It has been shown that both these methods result in minimal errors. A similar approach has been taken in calibrating the dose for a recent vault‐free radiosurgery … Show more

“…Following completion of acceptance testing and commissioning 10,12,13 of the ZAP-X unit, quality assurance procedures were established for measuring beam output, energy, profile, targeting accuracy (WL and E2E), overall dose delivery (DQA) and performance of the imaging system. Baseline data was obtained and trends in the aforementioned parameters were kept track of over time to verify that the performance of the first clinical ZAP-X unit were within standards and tolerances recommended by TG-142 9 , TG-135 8 and MPPG 9a 27 for SRS treatments.…”
