Figures & data
Figure 1. Example of PRF shift-based MR thermometry during MR-HIFU ablation therapy of a uterine fibroid. (A) Coronal (left) and sagittal (right) MR temperature maps obtained during HIFU sonication with a 16-mm treatment cell. The HIFU target can be seen to be heated to 68 °C (arrows) which was successful. Colour changes remote from the HIFU target are artefacts caused by motion (arrowheads). (B) Coronal (left) and sagittal (right) thermal dose maps immediately after HIFU sonication. Thermal dose contours for 240 EM (white line) and 30 EM (orange line) are demonstrated together (arrows). The semi-opaque brown ellipsoids represent the already ablated treatment cells.
