Retrospective Motion Correction in Gradient Echo MRI by Explicit Motion Estimation Using Deep CNNs
Mathias S. Feinler, Bernadette N. Hahn
Magnetic Resonance Imaging allows high resolution data acquisition with the downside of motion sensitivity due to relatively long acquisition times. Even during the acquisition of…
A class of regularizations based on nonlinear isotropic diffusion for inverse problems
Bernadette N. Hahn, Gael Rigaud, Richard Schmähl
Building on the well-known total-variation (TV), this paper develops a general regularization technique based on nonlinear isotropic diffusion (NID) for inverse problems with piece…
Using the Navier-Cauchy equation for motion estimation in dynamic imaging
B. N. Hahn, M. -L. Kienle-Garrido, C. Klingenberg +1
Tomographic image reconstruction is well understood if the specimen being studied is stationary during data acquisition. However, if this specimen changes during the measuring proc…
Detectable singularities from dynamic Radon data
Bernadette N. Hahn, Eric Todd Quinto
In this paper, we use microlocal analysis to understand what X-ray tomographic data acquisition does to singularities of an object which changes during the measuring process. Depen…
