Normalization of the task-dependent detective quantum efficiency of spectroscopic x-ray imaging detectors
Jesse Tanguay, Mats Persson
Spectroscopic x-ray detectors (SXDs) are poised to play a substantial role in the next generation of medical x-ray imaging. Evaluating their performance in terms of the detective q…
Development and evaluation of a 3D annotation software for interactive COVID-19 lesion segmentation in chest CT
Simone Bendazzoli, Irene Brusini, Mehdi Astaraki +7
Segmentation of COVID-19 lesions from chest CT scans is of great importance for better diagnosing the disease and investigating its extent. However, manual segmentation can be very…
Probing molecular excited states by atomic force microscopy
Shadi Fatayer, Florian Albrecht, Ivano Tavernelli +3
By employing single charge injections with an atomic force microscope, we investigated redox reactions of a molecule on a multilayer insulating film. First, we charged the molecule…
Detective quantum efficiency of photon-counting CdTe and Si detectors for computed tomography: a simulation study
Mats Persson, Adam Wang, Norbert J. Pelc
Purpose: Developing photon-counting CT detectors requires understanding the impact of parameters such as converter material, absorption length and pixel size. We apply a novel line…
A framework for performance characterization of energy-resolving photon-counting detectors
Mats Persson, Paurakh L. Rajbhandary, Norbert J. Pelc
Photon-counting energy resolving detectors are subject to intense research interest, and there is a need for a general framework for performance assessment of these detectors. The…
Robustness of Optimal Energy Thresholds in Photon-counting Spectral CT
Yifan Zheng, Moa Yveborg, Fredrik Grönberg +4
An important question when developing photon-counting detectors for computed tomography is how to select energy thresholds. In this work thresholds are optimized by maximizing sign…
