Multi-slice quantum Computed Tomography system using a MHSP

Abstract

The present work reports a new system for Computed Tomography (CT) with Multi-Slice (MS) capability using the 2D-MicroHole & Strip Plate (MHSP) detector. The system is based on the third generation of CT scanners and includes a MHSP based detector which achieves gains above 104 and has the capability to discriminate the interaction position of the incoming radiation in 2D. The possibility of operating in single photon counting mode with energy discrimination allows the selection of energy ranges for image reconstruction and the application of the Energy Weighting Technique (EWT). The EWT improves the image contrast and the Signal to Noise Ratio of the images. The reconstruction of three-dimensional images of a PMMA phantom with holes filled with chalk and air or brass are shown as a good representation of the studied objects. © 2012 IOP Publishing Ltd and SISSA.
