Field-Cycling 14N NQR Imaging with Spatial and Frequency Resolution
The recently developed technique of NQR imaging via field cycling has been used to image 14N nuclei in a test sample of acetamide and salicylamide. The image obtained is spatially resolved in one dimension and is also obtained as a function of the |0〉 → |+〉 transition frequency. The imaging plane is generated by two collinear solenoids wound with opposite handedness. In the field-cycling experiment, the 14N |0〉 → | +〉 transition is saturated throughout the sample except at the imaging plane where the magnitude of the RF field, |B1|, is near zero. © 1995 Academic Press, Inc.
