Figure 1.

a. Axial T2-weighted MR image acquired one day post-treatment showing a lesion in the VIM nucleus (arrow); b. Screenshot from the MRgFUS system console displaying a thermal dose calculation after a single sonication in the same patient (axial plane, zoomed in around the target). The green and yellow areas represent regions that received a thermal dose exceeding 240 and 17 CEM, respectively. The light green circle denotes the intended target zone (diameter ~ 2 mm). In this example, the frequency encoding direction was left-to-right, and an off-resonance-induced shift on the order of 2 mm was observed along this direction.
