WebIn a typical treatment plan for proton therapy, the spread out Bragg peak (SOBP, dashed blue line) shows how the radiation is distributed. The SOBP is the sum of several individual Bragg peaks (thin blue lines) at … WebPBT is delivered by very large, complex and expensive machinery. Unlike conventional X-ray radiotherapy, protons deliver the dose in a Bragg peak. By modulating the energy and position of the Bragg peak the dose can be painted over the tumour volume allowing more dose to be delivered to the tumour while sparing the healthy tissue surrounding it.
