Implementation of a complete IMRT QA program and clinical experience with the DAVID chamber for in-vivo verification of IMRT deliveries

Abstract

A complete IMRT QA program based on a combination of the 2D-ARRAY and the DAVID system was implemented in our clinic to verify all IMRT deliveries. The QA program covers the whole treatment process from pretreatment dosimetric plan verification to daily in-vivo verification of the treatment delivery. This enables us to detect any discrepancies that would occur before and also during the treatment. The DAVID system has been used regularly in our clinic to verify the daily treatment delivery and has been shown to be a convenient and fast tool to pin-point errors that might have occurred during each fraction. The IMRT program presented in this study is very reliable and adds only minimal workload to the clinical routine. © 2009 Springer-Verlag.
