Fig. 1From: High-intensity focused ultrasound ablation enhancement in vivo via phase-shift nanodroplets compared to microbubblesSchematic representation of the rat liver position with respect to the HIFU transducer. The acoustic focus was positioned ~7Â mm inside the liver. Up to four separate HIFU sonications were performed in each liver. MR thermometry was performed in a vertical plane through the HIFU focus for each sonicationBack to article page
