A desktop imaging system for teaching MR engineering.

This paper reports our results in developing a simple MRI system for teaching the basics of MR Engineering at the undergraduate or graduate level. LabVIEW data acquisition cards were used for generating and digitizing the RF signals and controlling gradients and transmit/receive and blanking switches. A very inexpensive and simple magnet reported previously by Sahakian was used to enable simple, projection reconstruction imaging. Students constructed the gradients, RF coils and did system level assembly and programming of the data acquisition system. At the end of the course students were tasked with identifying unknown imaging "phantoms" in their magnet, and then improving the image based on their knowledge.
