WitrynaIMRT dose verifications should be evaluated more accurately. Kly et al.14 showed that institutional patient-specific IMRT quality assur-ance (QA) does not necessarily detect unacceptable plans. In their study, 14% of plans accepted by institutional IMRT QA were described as fail by an audit. In other words, even if an IMRT plan is WitrynaAn accurate delivery of prescribed dose is essential to ensure the most successful outcome from advanced radiation treatments such as intensity modulated radiation therapy (IMRT). An anthropomorphic phantom was designed and constructed to conduct a remote-audit program for IMRT treatments.
