The prototype of EPID-based in vivo dose verification for VMAT treatments in patients with prostate cancer

Nowotwory, 2023
INTRODUCTION: The volumetric modulated arc therapy technique (VMAT) is now widely used in radiotherapy. Verifica­tion of the dose delivered to the patient is performed prior to the treatment (pre-treatment mode).
