Fig. 8From: Minimizing eddy currents induced in the ground plane of a large phased-array ultrasound applicator for echo-planar imaging-based MR thermometry(Top) Coronal images of patterns (a) to (f) in SPGR with calculated temperature maps. (Middle) Coronal images of patterns (a) to (f) in EPI with calculated temperature maps. The mean and standard deviations were calculated on 1458Â voxels of a predefined region of interest. (Bottom) Geometric distortion maps created by masks to generate about 4000Â voxels. Two different color scales are used to facilitate comparisonsBack to article page
