ABSTRACT:
An NMR zeugmatographic scanner is modified to provide motion images, During each measurement cycle the paramagnetic nuclei are subjected to a pair of transverse excitation field pulses which are separated by the application of a bi-polar magnetic field gradient which sensitizes the resulting FID signal to motion. The resulting FID signal is processed using an inverse Fourier transformation to produce images of flowing paramagnetic nuclei.
