Sensitive Plane
 
Technique of selecting a plane for sequential plane imaging by using an oscillating magnetic field gradient and filtering out the corresponding time dependent part of the NMR signal. The gradient used, is at right angles to the desired plane and the magnitude of the oscillating magnetic field gradient is equal to zero only in the desired plane.

Sequential Line Imaging
 
MR imaging techniques in which the image is built up from successive lines through the object. In various schemes, the lines are isolated by oscillating magnetic field gradients or selective excitation, and then the NMR signals from the selected line are encoded for position by detecting the FID or spin echo in the presence of a magnetic field gradient along the line; the Fourier transformation of the detected signal then yields the distribution of emitted NMR signal along the line.

Sequential Point Imaging
 
MR imaging techniques in which the image is built from successive point positions in the object. In various schemes, the points are isolated by oscillating magnetic field gradients (sensitive point) or shaped magnetic fields.
