The main advantage of proton therapy over conventional radiotherapy is the scheme of dose deposition: unlike X-rays, protons are fully stopped in patient’s tissues with a distinct maximum at the end of their range: the Bragg peak. Such a distribution allows for a precise coverage of a tumor volume while sparing the nearby healthy tissues. However, accurate control of the proton beam range is...

6. Labeling the tumor with 31-P, 63-Cu and 89-Y provides an in vivo prompt gamma-based range verification for therapeutic protons

Range uncertainty is a main limitation to fully exploiting the benefits of proton therapy. Its reduction will improve treatment effectiveness by increasing both dose conformality in the tumor and normal tissue sparing.

We present a proof of principle investigation of a range verification approach based on the detection of prompt gammas (PG), whose production is artificially enhanced with a...
