A YAG:Ce calorimeter with a 6×6 cm2 active area, long 10 cm has been manufactured in order to stop up to 200 MeV protons and to sustain 1MHz particle rate. It consists of four optically separated crystals assembled in the same housing. The YAG:Ce scintillator is promising for charged particle detection applications where high-count rate, good energy resolution and compact photodiode readout, not influenced...
Proton Computed Tomography (pCT) is a new imaging method with a potential for increasing accuracy of treatment planning and patient positioning in hadron therapy. A pCT system with small active area (5cm×5cm) has been already manufactured by authors. Tested under proton beams gave first promising results on radiography and tomographic reconstructions. Recent developments of a second prototype with...
Today, there is a steadily growing interest in the use of proton beams for tumor therapy, as they permit to tightly shape the dose delivered to the target reducing the exposure of the surrounding healthy tissues. Nonetheless, accuracy in the determination of the dose distribution in proton-therapy is up to now limited by the uncertainty in stopping powers, which are presently calculated from the photon...
Proton computed tomography (pCT) is a medical imaging method, based on the use of proton beams with kinetic energy of the order of 250 MeV, aimed to directly measure the stopping power distribution of tissues (presently calculated from X-rays attenuation coefficients), thus improving the accuracy of treatment planning in hadron therapy. A pCT system should be capable to measure tissue electron densities...
