Figure 4. Catheter tip-tissue interface imaging and lesion formation visualization on the atrial septum.

Figure 4

(A,G) Catheter tip localization from T1w-FLASH sequence. Green arrow indicates the position of catheter tip. (B–F and H–L) Temporal progression of lesion formation in the RA visualized by T2w-HASTE during RF energy delivery (20W, 120sec and 20W, 90sec respectively). Time after start of the ablation is shown in each image: (B) at the beginning of ablation and (C–F) at 10, 15, 30 and 240sec after the start of the ablation, respectively; (H) at the beginning of ablation and (I–L) at 18, 30, 42 and 78sec from the start of ablation respectively. RA: right atrium, and LA: left atrium.
