Abstract
An important element of a modern high-tech radiotherapy complex based on a linear electron accelerator is an electronic detector of portal images. It ensures the accuracy of the patient’s positioning on the treatment table, the compliance of the delivered dose distribution with the planned one, and allows for fast and accurate verification of treatment plans with volumetric modulation of the radiation intensity. The main provisions of the quality control of the electronic portal image detector are considered. It is shown that it includes the following stages: installation and commissioning of equipment; radiation dose control; calibration; quality control of clinical images; software testing; development of a quality assurance program that ensures the effectiveness and reliability of the patient’s radiation conditions in the course of radiation therapy.
