The heating pattern used to recreate the letters in the word ‘HIFU,’ consisting of straight lines. The order of the lines is shown using numbers 1 to 10. The transducer was moved first to the center of each letter, and each line was then produced by electronically steering the focal point along the 18-mm-long lines. LR denotes the left-right direction, and HF denotes the head-foot direction.
