Apparatus for generation of magnetic field gradient waveforms for NMR imaging

An apparatus is described for generating and controlling magnetic field gradients. It is used in conjunction with standard high-resolution NMR spectrometers to perform NMR imaging experiments. Profiles for gradients are digitally stored in separate memories which are loaded via a simple personal computer and are strobed out under spectrometer control. The system is versatile, low cost, simple to interface and use, and does not interfere with normal spectrometer operation. (author)
