Description
Time-of-flight ion computed tomography (TOF-iCT) is a promising imaging modality for improving dose conformity and range accuracy in ion beam therapy by enabling direct reconstruction of patient stopping power (SP) images using clinical ion beams.
The realisation of TOF-iCT critically depends on detector technologies that combine high spatial precision with ultra-fast timing to enable the reconstruction of individual ion tracks at clinically relevant beam intensities, a requirement that can be fulfilled by Low Gain Avalanche Diodes (LGADs).In this contribution, we present our new TOF-iCT demonstrator system, which consists of 12 single-sided LGAD strip detectors that can be simultaneously operated as a TOF-iCT system with a TOF-calorimeter and in the so-called Sandwich TOF-iCT mode.
In this contribution, we report on the development of a TOF-iCT demonstrator based on 12 single-sided LGAD strip detectors, operable with a TOF calorimeter or in the Sandwich TOF-iCT configuration. Imaging results from a sacrificed mouse are presented, along with ongoing efforts toward in vivo imaging of live mice. Key challenges related to fast 4D tracking of different ion species and the identification of nuclear fragments are discussed.
