title: A system for remote dosimetry audit of 3D-CRT, IMRT and VMAT based on lithium formate dosimetry.
abstract: The aim of this work was to develop and test a remote end-to-end audit system using lithium formate EPR dosimeters. Four clinics were included in a pilot study, absorbed doses determined in the PTV agreed with TPS calculated doses within ±5% for 3D-CRT and ±7% (k=1) for IMRT/VMAT dose plans.
