Research Projects: 

Dodecahedral Head Coil Development:

Development of an 8-channel Transmit-Recieve (TxRx) array, consisting of 8 capacitively decoupled loop element, placed with dodecahedral symetry. It has been constructed around a fiberglass helmet modeled to maintain a safe distance from an average human head norm for European males. This design allows for full brain coverage. It also allows for coil profile variation along the x, y, and z directions, which creates better control during parallel transmission acquisitions. A full comparison of this coil to the relative industry standard is in process.


Effects of Shielding on Surface Coil Loops at 7T:

Radiation power loss, or the radiated power of a coil that is not absorbed into a sample, is assumed to be a problem t high field in MRI, as it is known to increase with the frequency (w) and coil-bounding area (A): R_loss is proportional to A^2 * w^4. Various authors suggest that the effects of radiation loss, such as decreased SNR and coil Q, can be mitigated by adding RF shielding to coils used at high field. However, it is also know that shielding can reduce the effectiveness of a coil due to counter-rotating image currents in the shield. The effect of shielding on coil performance are being tested using the most simple case of a single Transmit-Receive (TxRx) coil, to quantitatively compare the benefits of shielding for radiation loss in both transmit and receive at high field. A single surface coil was chosen both because of its simplicity, and because, unshielded, it is the most susceptible to radiation loss because of its open structure at high field. The single-loop case is also being tested in simulations to compare with the experimental results.
