The proton computed tomography with VIPM an phantom: a simulation study

The proton therapy dramatically is increasing in the world. Because the range proton is a finite in matter, this treatment modality permits a comparable superiority with conventional external beam X-ray therapy. In current clinical particle, proton therapy treatment are made with pre-treatment X-ray the patient's CT scans. To convert the X-ray CT Hounsfield to proton relative stopping powers used a derived calibration function. However, the relationship between Hounsfield units and relative stopping power is not bilinear which be able to lead range uncertainties at planning timely treatment. The Proton Computed Tomography can be directly applied to treatment planning system in order to mitigate a range uncertainty
