Official Title: To Evaluate the Safety and Efficacy of High-intensity Focused Ultrasound (HIFU) for the Symptom Relief of Inoperable Abdominal Tumors
Brief Summary: High-intensity focused ultrasound (HIFU), a recently developed tumor ablation equipment, can be a non-invasive treatment for solid tumors. The principle of HIFU is physically focus the ultrasound point on the biological tissue to form high-intensity ultrasound focus, and kill tumor cells by the thermal effects, mechanical effects and acupuncture effects of the high-intensity ultrasound.
