HIFU Treatment of Benign Thyroid Nodules

High-intensity focused ultrasound (HIFU) is a non-invasive, non-invasive treatment method. The principle is to focus high-intensity ultrasound on the target area. Energy is absorbed by the target tissue and converted into thermal energy. The local temperature quickly reaches a maximum of 85 ° C. It induces coagulative necrosis of focus tissue cells, but does not damage the tissues surrounding the treatment targ
