Query: Dynamic imaging using Motion-Compensated SmooThness Regularization on
  Manifolds (MoCo-SToRM)   We introduce an unsupervised motion-compensated reconstruction scheme for
high-resolution free-breathing pulmonary MRI. We model the image frames in the
time series as the deformed version of the 3D template image volume. We assume
the deformation maps to be points on a smooth manifold in high-dimensional
space. Specifically, we model the deformation map at each time instant as the
output of a CNN-based generator that has the same weight for all time-frames,
driven by a low-dimensional latent vector. The time series of latent vectors
account for the dynamics in the dataset, including respiratory motion and bulk
motion. The template image volume, the parameters of the generator, and the
latent vectors are learned directly from the k-t space data in an unsupervised
fashion. Our experimental results show improved reconstructions compared to
state-of-the-art methods, especially in the context of bulk motion during the
scans.
