MO-A-18C-1 Monday 7:30AM - 8:30AM Room: 18C

The goal of this session is to introduce the audience to the physics, dosimetry and treatment planning procedures used in proton therapy. The course material covers the basic physics of proton interaction with matter and physical characteristics of clinical proton beams. It will provide information on proton delivery systems and beam delivery techniques for scattered and scanning proton beams. It will include the requirements for dosimetry measurements and present the equipment needed for commissioning of proton beams for clinical use and quality assurance checks as well as methods used for proton beam calibration and dose verification of patient treatment fields. The session covers the treatment planning strategies for various anatomical sites, methods to address uncertainties in proton therapy and uncertainty mitigation to generate robust treatment plans. Challenges involved in the motion management in proton therapy will also be discussed.

Learning Objectives:
1. Gain knowledge on physics, dosimetry, treatment planning and quality assurance for proton therapy.
2. Understand the uncertainties associated with proton therapy and currently used strategies for their mitigation in treatment planning.
