This dataset contains the phantom bSSFP phase-cycled measurement data used in the published article: Schäper et al. 'Pure balanced steady-state free precession imaging (pure bSSFP)', Magn Reson Med. 2022;87:1886-1893 (doi: 10.1002/mrm.29086). The acquisitions were made with a 3 T MRI system (Magnetom Prisma; Siemens Healthcare, Erlangen, Germany) using a 20 channel head coil. The data contains four datasets for different TR values (1.5 ms, 3 ms, 5 ms and 8 ms), each was measured with eight phase cycles (0°, 45°, 90°, 135°, 180°, 225°, 270° and 315°).
