A laboratory demonstration of spatial encoding in MRI
The solution at hand describes a low-cost, small-scale MRI system which has been shown to demonstrate 1-dimensional spatial encoding. The main motivation for constructing the apparatus is its need for educational and demonstration purposes in biomedical engineering courses. The hardware and software is designed to be as simple as possible. A MATLAB program directly controls a microprocessor over a serial RS232 line. Our evaluation with four selected students revealed that they enjoyed completing the activity and they improved their understanding of some basic MRI concepts. Students reported that the system made the MRI concepts become visible and easy to comprehend. American Society for Engineering Education, 2006.
