Description of how MRI sequences spatially encode nuclei in the read and phase direction
Differences that occur in an induced magnetization in biological tissues in a magnetic field cause image contrast in MRI. A signal measured by the receiver coils is the integral of an induced magnetization over the whole imaged volume. To construct a three-dimensional distribution of magnetization, a spatially varying field pattern is generated in the volume, such that voxels at various parts generate a signal that is tagged with data on the location. Standard techniques for spatial encoding in MRI create high-quality images. In magnetic resonance imaging technique, two main methods (SVD MRI and SMASH MRI) are used to modify ...
