Workshop Description:

The aim of this workshop is to provide overview of 3D polymer gel manufacture, calibration and application to radiotherapy patient specific QA verification.

Advanced radiation therapy techniques such as Rapid Arc, Tomotherapy and Stereotactic Radiosurgery require comprehensive pre irradiation patient specific QA verification. Comprehensive dose verification for these techniques requires dosimeters that are able to measure complex three-dimensional dose distributions accurately and with good spatial resolution. Existing dose verification QA techniques depend on ion chambers, 2-D arrays of diodes or ion chambers, MOSFETs, diodes in water phantom or films. The main difficulties associated with these devices are that they cannot provide 3D dose verification, most of them are not tissue equivalent which may perturb the radiation field and some have relatively large volume to limit achievable spatial resolution. A potential solution for all of these problems has emerged in the form of water equivalent three dimensional gel. 

This workshop will cover:

• An overview of the preparation and manufacture of 3D gel
• An overview of optical CT scanning of the gel
• Calibration and patient specific QA procedure for Rapid Arc, Tomotherapy and CyberKnife patients using 3D gel
