Energetic proton beams (60-230MeV) are used in proton therapy. Currently, x-ray imaging is used before each proton therapy treatment to accurately tune the proton beam, but the conversion to proton range introduces an error up to 3%, which could be cut by using proton imaging instead. At this moment no device for proton imaging is available on the market. We propose a GaN detector for proton...

Flash radiotherapy (RT), characterized by the delivery of ultra-high dose rates (UHDR), recently demonstrated a reduced toxicity towards surrounding non-malignant tissues while mantaining damage efficiency and tumour control. Conventional dosimeters, as ionization chambers and thick solid state detectors, under UHDR beams suffer of unwanted effects as e.g. ion-recombination effects. The...

6. The PETALO project

Talk

PETALO (Positron Emission TOF Apparatus with Liquid xenOn) is a project that uses liquid xenon (LXe) as a scintillation medium, silicon photomultipliers as a readout and fast electronics to provide a significant improvement in PET-TOF technology. Liquid xenon allows one to build a continuous detector with a high stopping power for 511-keV gammas. In addition, SiPMs enable a fast and accurate...

204. Pushing the Limits of TOF-PET Detectors: Advancements in Timing and DOI Evaluation

Talk

Achieving excellent time resolution is crucial in time-of-flight (TOF) positron emission tomography (PET) for improving the signal-to-noise ratio and image quality. High-frequency (HF) front-end electronics offer a solution for achieving excellent performance in TOF-PET applications by exploiting the fastest light production mechanisms in crystals. Moreover, as the achievable coincidence time...

302. Nuclear fragment tracking for the assessment of the quality of ion-beam radiotherapy

Dr Maria Martisikova (German Cancer Research Center)

Talk

Radiotherapy with ion beams is a highly precise cancer treatment modality. As such, its quality might be influenced by even minor anatomical changes within the patient like swellings or tumor shrinkage. Therefore methods to assess the quality of the treatment during the irradiation is of utmost interest.
Contrary to X-ray imaging, methods without exposing the patient to additional radiation...
