摘要：
A new NMR imaging technique is described. A selective excitation is given in a line-shaped focusing field. The spin distribution in the one-dimension line-shaped excitation region is detected with a linear magnetic field gradient. The methods of generating the line-shaped magnetic focusing field and its scanning are described together with the selective excitation characteristic. Experiments of imaging with an 819-kHz pulsed NMR system and their results are shown. The data collection time of the method was examined, showing much shorter time than conventional line-scanning methods.
