Pilot scale validation campaign of gel dosimetry for pre-treatment quality assurance in stereotactic radiotherapy.

Purpose: Complex stereotactic radiotherapy treatment plans require prior verification. A gel dosimetry system was developed and tested to serve as a high-resolution 3D dosimeter for Quality Assurance (QA) purposes.

Materials And Methods: A modified version of a polyacrylamide polymer gel dosimeter based on chemical response inhibition was employed.
