Web• Conversely, if partial Fourier is used in one direction, the other k-space directions must be processed first with the normal algorithm. • Consider a 2-D case in which full Fourier acquisition is used in k x direction whereas partial Fourier is used in the k y direction. • Taking 1-D F.T. of the fully sampled k x direction results in WebAll fast brain MRI scans included half-Fourier acquisition with single-shot turbo spin echo (HASTE) sequences in the axial, coronal, and sagittal plane. Two neuroradiologists … WebPartial echo is a technique that is similar to Half Fourier. It will allow technologists to shorten their scan time by only filling half the K space in the frequency direction. Since the right and left side of our K space are … pinching on left side of stomach
