By adjusting the electrical permittivity of the material in the bath and adding slots to the conductive ground for the ultrasound array in MR-guided focused ultrasound it is possible to go from a situation where the ultrasound array and associated fluid bath detrimentally affect the RF fields for MRI and prohibit effective imaging in the Region of Interest, to where they actually enhance it, thereby improving image quality.
