Abstract

MR compatible hyperthermia devices exploit MR thermometry capabilities for non-invasive treatment monitoring. These devices, which have been tested to be MR-safe, can potentially influence the MR image quality. One such device is the Pyrexar BSD-2000 3D/MR applicator. In this study, we quantitatively evaluated the impact of the applicator for different setups on MR imaging by B1 + and signal-to-noise (SNR) measurements. Our results show 30% decrease in the B1 + transmit efficiency and 20% decrease in the SNR. We have found the biggest impact was caused by the device's water bolus. This effect can be overcome by increasing the B1 transmit gain or using a thinner water bolus in the device design.
