(SPCR) is able to identify and distinguish different crystals associated with arthropathies in …

Existing technologies used to detect monosodium urate (MSU) crystals for gout diagnosis
are not ideal due to their low sensitivity and complexity of operation. The purpose of this …

Multi-energy computed tomography (CT) with photon counting detectors (PCDs) enables
spectral imaging as PCDs can assign the incoming photons to specific energy channels …

ROI analysis is frequently used for obtaining acid content on rapid-kV-switching dual energy
CT (DECT), providing inadequate accuracy. A new parameter derived from post-processing …

This thesis reports on improvements in crystal arthritis diagnosis that we have obtained
using the MARS spectral photon counting imaging system. It also reports on how this system …

4.1 Background Computed tomography (CT) for medical purposes was first reported in 1973
[1, 2] and became more widely available in the 80s. CT was an instant success in the …
