Description
Time-of-flight ion computed tomography (ToF-iCT) is a promising imaging technique for ion beam therapy, offering the potential to enhance dose conformity and range accuracy through the direct reconstruction of patient stopping power distributions. In this contribution, we present a ToF-iCT demonstrator that has been tested using a medical ion beam. This places demanding requirements on the imaging system, particularly with regard to rate capability, spatial and timing performance, and the material budget. The demonstrator is based on twelve single-sided strip low-gain avalanche diodes (LGADs) in an orthogonal arrangement, which enable single-particle tracking and energy estimation through time-of-flight measurements. We will report on recent developments and research activities, present imaging results from an ongoing imaging campaign, including in vivo imaging of live mice, and outline a use case for range verification with mixed beams, together with the results of the first experiments.
