Towards Fragment Distinction in Therapeutic Carbon Ion Beams: A Novel Experimental Approach Using the Timepix Detector

Popis výsledku v původním jazyce

Radiotherapy with carbon ion beams is a highly precise method for cancer treatment. This is due to the finite range and the relatively low lateral scattering of the ions. However, on their path through tissue, the carbon ions may undergo nuclear fragmentation, resulting in lighter but energetic projectile fragments. Since the biological effect of the fragments differs from the primary particles, it is important to consider fragmentation in beam models used for therapy planning. Until now, large apparatus have been utilized for ion spectroscopic measurements. Employing a small detector would allow investigations directly within therapy relevant phantoms.We used the Timepix detector, consisting of a 300m thick silicon sensor bump-bonded to a readout chipwith 256 x 256 square pixels (55m pitch). The high spatial resolution enables to visualize and distinguish tracks of single particles. The pixel-wise energy calibration allows to directly determine the particle energy loss in the sensiti
