Construction of a Specialized Radiofrequency Coil for Mouse Cardiac MR Imaging [Ugrad Project]
Stavros Gagarelis, B.S.
This project focuses on the simulation of the response of various coil geometries using the software Remcom XFdtd 7.0.2 and Matlab 7.1. The efficiency of all coils is compared and the similarity of the magnetic field simulation response compared for the two employed simulation environments.
Each coil was simulated both in free space and with an integrated mouse mesh (scaled down rodent model), in an effort to show possible magnetic field effects on organs due to the coil presence.
The final step of the project involved the implementation and fabrication of the coils and the subsequent testing on C57BL/6 male mice (in vivo and post-mortem).
