How does it work?
You must have tried to burn a paper in childhood by focusing sun rays through magnetic lens on the paper. This is what happens in focused ultrasound surgery. This type of surgery is based on the principle of energy transformation, wherein high intensity ultrasound is focused on a single part of the body that has to be dissolved. When such high intensity energy is transferred to a single point, temperature significantly increases. The phenomenon is also called thermal ablation. UItrasound has this impeccable property to travel through water and soft tissues in the body. Due to the intense heat created due to ultrasound a powerful mechanical force gets created which liquefies the target tissue, which in medical terms is called histotripsy. Physicians with the help of ultrasound try to produce enough heat and vibration in the minutest part of the body that has to be treated. It is possible to pinpoint even a tumor of the size 1mm deep inside the body without causing any harm to the adjacent parts. The destroyed tissue gets absorbed by the body.
As of now, no such serious side effects are known for this surgery. However, passing ultrasound through body could have its own inevitable disadvantages. But, on a large scale patients do get benefited which and through a painless process can cure their life threatening diseases.
