PPT-Background / Aim Conventional proton beam range verification using PET relies on tissue

minimal activation near the end of the proton range perfusiondriven activity washouts and short halflives of progeny radioisotopes which requires an inbeam inroom or onsite PET scanner While the installation of such a PET scanner can be financially and technically challenging for many proton centers previous work Cho .
