Temperature mapping for transcranial MRgHIFU. A compressed sensing method called temporally constrained reconstruction (TCR) is used to reconstruct 3D temperature maps during in-vivo brain imaging using k-space data subsampled with a factor of 6x. 1.5 mm × 2.0 mm × 3.0 mm resolution (zero-filled to 1.0 mm isotropic spacing), 288 mm × 216 mm × 108 mm FOV, and 1.8 s per time frame was achieved. The rows shown sagittal, axial, and coronal slices through the 3D imaging volume, and the columns show magnitude images, temperature maps, and temperature standard deviation maps.
