A review of proton therapy – Current status and future directions

Precision Radiation Oncology, 2022
The original rationale for proton therapy was its highly conformal depth‐dose distributions compared to photons, which allow greater sparing of normal tissues and escalation of tumor doses, thus potentially improving outcomes.

Daily adaptive proton therapy: Feasibility study of detection of tumor variations based on tomographic imaging of prompt gamma emission from proton–boron fusion reaction

Nuclear Engineering and Technology, 2022
In this study, the images of specific prompt gamma (PG)-rays of 719 keV emitted from proton–boron reactions were analyzed using single-photon emission computed tomography (SPECT). Quantitative evaluation of the images verified the detection of anatomical

Clinical implementation and validation of an automated adaptive workflow for proton therapy

Physics and Imaging in Radiation Oncology, 2022
Background and purpose: Treatment quality of proton therapy can be monitored by repeat-computed tomography scans (reCTs). However, manual re-delineation of target contours can be time-consuming.
