A Laboratory Demonstration of Spatial Encoding in MRI

Abstract 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 ac- tivity 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.

1 Introduction Magnetic Resonance Imaging (MRI) has not only become one of the most impor- tant diagnostic tools in medicine, but there are also MRI courses available at nearly all university biomedical engineering departments. The reasons for its widespread popularity are obvious. MRI is capable of producing high resolution images, see figure 1; this allows diagnosis of a large number of health problems and disorders such as tumors, abscesses, blood flow congestions, heart malfunctions and joint problems. For example, MR Angiography deals with the localization and imaging of blood vessels by observing signal amplitude changes and the resultant phase. Furthermore, there are fields other than medicine which benefit from MRI, such as psychology, in which MRI is used to study brain activity in different kinds of situations.

MRI not only provides high resolution images, but also provides significant
