Dose energy dependence in proton imaging with thin detector

Since the earliest works proposing the use of protons for imaging, the main advantage of protons over X-rays was expected to be a result of the specific property of the proton flux dropping off very steeply at the end of the particle range. This idea was declared but was not checked. In the present...

Summary:Since the earliest works proposing the use of protons for imaging, the main advantage of protons over X-rays was expected to be a result of the specific property of the proton flux dropping off very steeply at the end of the particle range. This idea was declared but was not checked. In the present work, this assumption was investigated using the Monte Carlo simulation for the case of registration of protons with a thin detector. ► Principal idea of proton imaging “to work at the end of the range” was tested. ► The case of thin detector was investigated. ► The dose energy dependence was calculated using computer simulation.
