Ring Artifact Correction in Photon-Counting Spectral CT Using a Convolutional Neural Network With Spectral Loss
Dennis Hein, Konstantinos Liappis, Fredrik Grönberg +2
Photon-counting spectral computed tomography is now clinically available. These new detectors come with the promise of higher contrast-to-noise ratio and spatial resolution and imp…
Dimensionality and Background Cancellation in Energy Selective X-Ray Imaging
Fredrik Grönberg, Mats Persson, Hans Bornefalk
Purpose: The set of linear attenuation coefficients that belong to materials in the human body is commonly assumed to be spanned by two basis functions in the range of clinical x-r…
Reconstructing Accurate Synthetic Hounsfield Units with Spectral CT Data
Fredrik Grönberg, Hans Bornefalk
Purpose: To evaluate a proposed method to reconstruct CT numbers that accurately mimic conventional CT numbers from spectral CT data, as would have been produced by a conventional…
The effects of intra-detector Compton scatter on zero-frequency DQE for photon-counting CT using edge-on-irradiated silicon detectors
Fredrik Grönberg, Zhye Yin, Jonathan Maltz +2
Background: Edge-on-irradiated silicon detectors are currently being investigated for use in photon-counting CT applications. The low atomic number of silicon leads to a significan…
