Thermoluminescent chip detector for in vivo dosimetry in pelvis and head & neck cancer treatment

Our aim is to show the TL dosimetry as a confident QA method for radiotherapy treatments. Before in vivo entrance dose measurements using TLD-100 chips, ECLIPSE TPS-simulated treatments for a Rando anthropomorphic phantom, two for pelvis and one head & neck. In Vivo measurements results with 60Co beam remained within ±5% limits. Results for 6 and 15 MV are in conclusion. This is a National Cancer Institute/RJ/Brazil study under the 13.111—IAEA Coordinated Research Project.
