In the study carried out in goats, we used the JC200 focused ultrasound tumor therapeutic system (Chongqing Haifu Tech Co., Ltd, China). The therapeutic ultrasound energy is produced by a transducer with a focal length of 160mm, at a frequency of 0.8MHz. The animals (n=6) were divided into a control group (n=3) and an experimental group subjected to costectomy (n=3). Costectomy was performed 1 week before HIFU. There was no difference in the coagulation volume between the two groups. Skin burns accompanied with reddish color and focal edema were observed in two goats. There were no other complications. In the clinical study, HIFU was applied in patients with with ⩽ 3 lesions of liver carcinoma ⩽ 4cm in diameter. The complications and anti‐tumor effects on liver carcinomas should be evaluated. Tumor ablation was complete in 5 of 6 patients. There were no complications such as skin burns and local pain. HIFU did not influence blood chemical findings.
