SUMMARYNMR images of distinct sections through a three‐dimensional phantom were obtained using steady magnetic fields much less uniform than those generally considered necessary for NMR imaging, but whose substantial gradient served to define the slices to be imaged. A sensitive point technique and a modified spin‐echo pulse sequence were used.ABSTRACTNMR images are generally produced in highly uniform steady magnetic fields, to which switched gradients are added to achieve spatial selection. In this note we show that NMR images can be produced in a substantially non‐uniform field, provided the field is shaped so that the gradient of the steady field can be used to define the slice to be imaged.
