AB-CT performed at 5th Workshop on Medical Applications of Spectroscopic X-ray Detectors, 13-16 May 2019, CERN, Geneva, Switzerland

The workshop focuseed sharply on all aspects of the medical applications of spectroscopic X-ray detectors by inviting experts in the various domains which contribute to the development of the field. Clinicians, radiologists, biologists, tracer developers, imaging system specialists and detector and ASIC developers exchanged information and knowledge about the latest developments.

Daniel Kolditz, CTO of AB-CT, gave a lecture on the topic: Technical characteristics and initial clinical patient results of a photon-counting spiral breast-CT system.

Abstract:

Technical overview of the photon-counting breast CT system and its performance, the first clinical patient results and an outlook of potential applications.

Photon-counting spiral breast computed tomography (BCT) is a novel approach in breast imaging. It provides high resolution at very low dose using novel direct-conversion photon-counting detector technology combined with a spiral CT acquisition concept. The system (type nu:view, AB-CT – Advanced Breast-CT GmbH, Erlangen, Germany) presented here has received CE mark in 2018 and is available in clinical use. Performance tests showed a superior image quality compared to mammography, breast tomosynthesis, clinical CT as well as cone-beam breast CT systems based on conventional indirect converting X-ray detectors. The first clinical results confirm that the superposition-free 3D images are optimal for soft-tissue differentiation and micro-calcification characterization and this at dose level of mammography.
