Comparison of Excitement Methods of Vibrant Wire Sensors

Abstract

Students in developing countries like Ghana do not have easy access to sophisticated medical
equipment like Magnetic Resonance Imaging (MRI), Computer Tomography (CT) and Ultra sound
Scanners. This is due to the fact that these imaging equipment are highly expensive. As a result of this,
the students lacked the requisite practical experiences in these equipments during their training. In
addition, the understanding of the basic concepts behind the operation of these equipments becomes
difficult as they only have to imagine what is written in the books. To address this problem, a virtual
laboratory has been designed as a teaching aid to resolve the problem. In this work, the MRI machine
was used as a case study where the student logs in into the virtual MRI laboratory and will undergo the
necessary tutorials on the mode of operation and design features of the MRI machine. The virtual
laboratory, as teaching aid, saves time and would help the students in learning basic and advanced
concepts through remote experimentation (Chu, 1999). Other medical imaging equipment can also be
incorporated into this design.
