Abstract

X-ray fluorescence CT (XFCT) imaging is a promising molecular imaging modality with high spatial resolution and non-radioactive high atomic number tracers for medical imaging. While dozens of bench-top experiments proofed the concept of the approach, scalability for clinical systems with high molecular sensitivity at acceptable doses is not yet accomplished. This study compares a spectroscopic CdTe detector which was used for XFCT measurements beforehand to a CZT detector with scalable active area. The results show that the CZT detector is able to provide better image quality due to higher detection efficiency even with a significantly reduced energy resolution and absorbing enclosure.
