Low level spatial models will realize spatial constraints, and higher level spatial models will be created from patient-specific spatial reference data. (2) Develop spatial model-based reconstruction methods for sparsely sampled dynamic MRI datasets. These models will allow for a large increase in volume coverage without concomitant SNR reductions. (1) Develop and incorporate low level (constraints on changes of intensity over time) and higher level (parameterized) temporal models within reconstruction methods for sparsely sampled dynamic MRI datasets. Temporal and spatial models are proposed to be incorporated into the reconstruction of dynamic contrast enhanced (DCE) MRI data within an inverse problem framework. This will have a profound impact on dynamic MRI.

Please credit this website and the JMRI paper above if this code or data are used in an abstract or paper.stcr_2d.m is the main reconstruction function that implements the 'Spatially and Temporally Constrained Reconstruction (STCR).use run_stcr.m to reconstruct and view images.The STCR package contains two undersampled 24 ray radial, 50 time frames, cardiac perfusion datasets that were acquired on a Siemens 3T scanner are included (k_space*mat)

Temporally Constrained Reconstruction of Dynamic Cardiac Perfusion MRI. A tool in PostView identified these regions and calculated the surface area in each paired set of articular regions. Coverage was defined as the surface area on each of the two mated articular surfaces that contained an intersection of normal vectors (Fig. Journal of Magnetic Resonance Imaging (JMRI), 29:466-473, 2009 The isolated areas of interest were then used to perform the coverage analysis. STCR is a matlab-based program to reconstruct undersampled DCE radial data, with Compressed Sensing methods.Īcquisition and reconstruction of undersampled radial data for myocardial perfusion MRI.

For each participant’s original bone reconstructions, the general regions of interest for articulating surfaces of the subtalar joint (posterior and anteromedial facets) were isolated using values of 2nd principal of curvature calculated in the PostView software (v2.1.0, FEBio Software Suite, University of Utah, Salt Lake City, UT).
