Proton therapy is a cancer treatment technique currently in growth worldwide. It offers advantages with respect to conventional X-ray and $\gamma$-ray radiotherapy, particular, better control of the dose deposition allowing reach higher conformity treatments. Therefore, it causes less damage surrounding healthy tissue secondary effects. However, order take full advantage its potential, improvements planning verification are required. A new prototype proton Computed Tomography scanner...
Osteosarcoma is a radioresistant cancer, and proton therapy promising radiation alternative for treating cancer with the advantage of high dose concentration in tumor area. In this work, we propose use iodine-substituted hydroxyapatite (IHAP) nanomaterials to iodine (
Abstract Treatment planning systems at proton-therapy centres entirely use X-ray computed tomography (CT) as primary imaging technique to infer the proton treatment doses tumour and healthy tissues. However, stopping powers in body, derived from images, suffer important proton-range uncertainties. In order reduce this uncertainty range, one could proton-CT images instead. The main goal of work is test capabilities a newly-developed scanner, based on set tracking detectors high energy...

The 12 C (α, y) 16 O reaction is important in the production of universal , but its cross-section at relevant energies static helium burning complex and uncertain. total originates from a sum resonance tails direct captures, making contributions sub-threshold states difficult to estimate. One proposed method estimate these involves determining reduced α-widths through indirect measurements. Therefore, 19 F ( p α y ) was used populate α-unbound using 2.6 MeV proton beam on CaF 2 target. A...
Proton imaging has been proposed as an alternative low-dose technique for acquiring relative stopping power (RSP) maps and patient positioning. In proton therapy hadrontherapy, the water equivalent thickness (WET) of a material represents its radiological thickness, however, calculation requires computationally intensive methods or approximate solutions. At IEM-CSIC, we have developed scanner prototype with protons composed two double-sided silicon strip detectors (DSSSD) fast scintillators...
