Intracheck IORT beam daily checking

Project Description

The aim of this work was to develop a phantom with embedded detectors to improve both accuracy and efficiency in the daily test of an IORT linac at the surgery room. The developed phantom is locked using the same existing docking system. It allocates 6 parallel-plate chambers to evaluate the output, energy constancy, flatness and symmetry, analyzed by a specific application. It allows a very efficient setup, improving time, and providing a complete dosimetric information with just a shot and using ionization chambers with minimum saturation effect as this highly pulsed beam requires.
