Abstract
External beam proton therapy (EBPT) treats cancer by delivering small daily fractions of ionizing radiation to a target volume. For prostate cancer, the target undergoes day-to-day geometrical variations in position, volume, and shape. Accurate treatment delivery requires management of daily variations. (Water-filled) Endorectal balloons (ERBs) can be used to limit these variations. However, patterns of variations for patients with ERB have not yet been investigated. We used point set non-rigid registration and statistical modeling to extract and model patterns of geometrical variations for patients with EBRs. Non-rigid registration was optimized to ensure high accuracy.
