What is it about?
Proton beam therapy (PBT) uses protons to destroy cancer cells, but it is difficult to know where in the body they hit during the irradiation. A possible way to answer this question is to detect the gamma rays produced during the irradiation and determine where in the body they are produced. This work investigates the use of collimators to determine where the proton interactions occur.

Why is it important?
Our findings show that the use of gamma ray detectors and collimators outside the patient's body can help determine where in the body the proton beam is hitting. This is extremely important for the medical industry to refine the applicability of PBT.
Perspectives
The results of this investigation must now be adapted to the type of gamma rays produced by PBT when it hits different parts of the body. This will be done in a sequel to this investigation
