Objective To study the clinical safety of high intensity focused ultrasound (HIFU) in the treatment of malignant solid tumors in vitro. Methods 16 4 cases of malignant solid tumor were treated with HIFU in vitro. The systemic and local changes after treatment were observed. Results During the treatment, the vital signs of patients were stable after treatment, and the function of the main organs was basically normal. There was no rupture or hemorrhage in local tumor, no jaundice or bile leakage, and no adjacent organ or blood vessel damage was found.
