PROJECT TITLE :

A Novel Method to Decrease Electric Field and SAR Using an External High Dielectric Sleeve at 3 T Head MRI: Numerical and Experimental Results

ABSTRACT:

Materials with high dielectric constant (HDC) have been utilized in high field MRI to decrease specific absorption rate (SAR), increase magnetic field intensity, and increase signal-to-noise ratio. In previous studies, the HDC materials were placed within the RF coil decreasing the area accessible. This study describes an alternative approach that considers an HDC-based sleeve placed outside the RF coil. The results of an HDC on the electromagnetic (EM) field were studied using numerical simulations with a coil unloaded and loaded with somebody's head model. In addition, experimental EM measurements at 128 MHz were performed within a custom-made head coil, fitted with a distilled water sleeve. The numerical simulations showed up to forty% decrease in maximum ten g-avg. SAR on the surface of the pinnacle model with an HDC material of barium titanate. Experimental measurements also showed up to twenty% decrease of most electrical field using an HDC material of distilled water. The proposed technique will be incorporated in the planning of high field transmit RF coils.
