Latent space reconstruction for missing data problems in CT

open access: yesMedical Physics, EarlyView.
Abstract Background The reconstruction of a computed tomography (CT) image can be compromised by artifacts, which, in many cases, reduce the diagnostic value of the image. These artifacts often result from missing or corrupt regions in the projection data, for example, by truncation, metal, or limited angle acquisitions.

The effect of concomitant gradient fields on MRI with long readout radial‐based trajectories

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To demonstrate in theory and practice that concomitant gradient fields (CCGF) can produce substantial imaging artifacts in scans utilizing radial‐based trajectories and to provide strategies to mitigate these effects. Theory and Methods A framework was developed to relate concomitant gradient phase to local point‐spread‐function ...
