Scientists have found a new technique to kill the damaged tissues of the brain. This technique uses ultrasound waves to kill the damaged tissues. High intensity ultrasound is used to heat up parts of the brain so that the damaged tissues are killed. This technique which was once termed as science fiction is now the reality and this ultrasound surgery has been performed on nine human beings and they have turned out to be successful.
The best thing in this invention is that one can make deep lesions in the brain with utmost accuracy and safety. The older methods used radio frequency ablation or a radio surgery. But this technique is faster than the other methods. In this technique, the specific point where the damaged cells have to be killed is focused by the ultrasound beams. The brain tissue absorbs the ultrasound energy and converts this to heat energy which raises the temperature at that point, thus killing the cells. A magnetic resonance scanner is used in this technique which helps the scientists to focus on the correct point of the brain tissue.
