Abstract: We have developed an NMR micro-imaging system in our laboratory. It features low cost, high performance, simple and convenient operation, as well as easy maintenance. This system may be divided into two parts. The hardware part mainly includes a Selective Excitation Unit (SEU), three channels of Pulse Gradient field Unit and two micro-imaging probes with RF coil diameters of 5mm and 25mm, respectively. Whereas the software, integrating with real-time control and waveform generation, was implemented with Delphi 2.0. The operation of our system is rather simple, i.e. the users need only to set or choose waveform from the list on the form, and to write a proper pulse program on the NMR spectrometer. Since our MRI system includes SEU, PFG unit and micro imaging probeheads, we believe, it will be used in various fields of research.
