This session will present dosimetry tools and techniques for intensity modulated radiation therapy based on the AAPM Task Group 120 report. First, advantages and disadvantages of different detectors including ion chambers and 2D dosimetry systems will be discussed in the context of IMRT distributions. Second, considerations with respect to phantoms will be discussed. Next, the application of different dosimetric analysis tools will be presented. The final topic is the next generation of detectors for QA such as polymer gels. The educational objectives of this session are to provide information to: 1. Determine the best detector for a given measurement scenario 2. Assess the impact of phantom selection on the measurement 3. Understand the benefits and limitations of different analysis tools for evaluating calculations and measurements of IMRT fields 4. Learn about new dosimetry systems for IMRT measurements.
