Description
Accurate dose delivery in scanned particle therapy requires a precise connection between the physical beam and the treatment planning system (TPS). This lecture covers the principles of dose delivery commissioning and verification, emphasizing how measured beam data build and validate TPS models. Key topics include beam data acquisition, depth/lateral dose modeling, and absolute dose calibration. The lecture also examines the effects of spot size, spacing, and scanning grid on homogeneity and efficiency. Experimental validation uses simple and complex geometries, as well as end-to-end tests from imaging to delivery. Demonstrated agreement between measurements and calculations confirms system control and ensures reliable clinical dose delivery.
