The goal of this session is to introduce the audience to the physics, dosimetry, treatment planning techniques, and quality assurances (QA) procedures used in proton therapy. The course material covers the 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 double scattering (DS), uniform scanning (US), and pencil beam scanning (PBS). The session covers the treatment planning strategies used in DS, US, and PBS 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. It will also include the methodology for proton beam dosimetry for clinical commissioning, beam calibration, and quality assurance checks. Learning Objectives: 1. Gain knowledge on physics, dosimetry, and treatment planning for proton therapy including intensity modulated proton therapy. 2. Be acquainted with the procedures involved in machine and patient treatment field specific QA. 3. Understand the uncertainties associated with proton therapy and currently used strategies for their mitigation in treatment planning.
