3D Beam Monitoring for 12C Radiotherapy by Tracking of Secondary Ions Using the Timepix Detector

Popis výsledku v původním jazyce

Radiotherapy with narrow 12C ion beams enables treatment of tumors with high precision while sparing the surrounding healthy tissue. Unpredictable changes in the patient's geometry can alter the ion range and result in changes in the dose distribution. Therefore, it is desirable to verify the actual dose delivery in the patient, preferably in real-time and in a non-invasive manner. Currently, the only technically feasible dose delivery monitoring method is based on tissue activation measurements by means of positron emission tomography (PET). As an alternative to PET-based measurements, beam range monitoring exploiting the detection of prompt secondary ions has been suggested. This modality is expected to allow for real-time monitoring, thereby reducing the influences of physiological signal wash-out known from PET-based techniques. In this contribution, the potential of monitoring narrow 12C ion beams in a head-sized PMMA phantom by tracking of secondary ions is investigated experimen
