3T Siemens Skyra System acquiring bSSFP based CINE cardiac data from a healthy volunteer. Cartesian Data: 8-fold undersampled data with the TPAT acquisition strategy. Radial Data: 24 spokes per frame 24 prospective cardiac phases were acquired in 3.3 s (Cartesian) and 3.2 s (radial), i.e. two heart beats, with a temporal resolution of 42.72 ms. Common sequence parameter were: TE=1.78 ms, FA=57 deg, matrix=224×184 (Cart.) resp. 224×224 (rad.). Siemens measurements files were converted to the ISMRMRD standard (http://ismrmrd.github.io/) with the siemens_to_ismrmrd tool The corresponding reconstructions with ICTGV in the AVIONIC framework was presented at the ISMRM Workshop for Data Sampling and Image Reconstruction, Sedona, USA 2016 (https://www.ismrm.org/workshops/Data16/) http://cds.ismrm.org/protected/Data16/Program/Abstracts/Schloegl.pdf
