The procedure begins with cleaning the area to be sonicated with alcohol swabs so that there are no germs and bacteria. In the next step, a gel is applied to your skin. Magnetic resonance imaging (MRI) or ultrasound is used to focus the exact tissue, organ or tumor that needs to be treated. The individual is sedated to avoid discomfort and pain during the procedure. After this, the procedure differs according to the purpose of HIFU. In general, an acoustic lens is used to focus sound waves on the targeted organ. The transducer device is used to emit sound waves. The sound waves propagate through the various layers of skin to reach the tumor to be destructed. When sound waves reach the tumor, heat is produced there increasing the temperature up to 90°C in 20 seconds only. This heat starts destroying the cancer cells there.
