Scientists have created a painless non-invasive endoscopy (video)

Specialists from Carnegie Mellon Universityinvented the method of optical visualization of internal organs based on ultrasound. Thanks to her, all internal organs and tissues can be studied without the use of the now familiar invasive endoscopic diagnosis. Thus, the discovery will allow to examine in detail the stomach, brain and other organs non-invasively, and therefore, completely without pain and without traumatizing the human biological tissues.

With endoscopic examination in the bodypatient injected chamber. The procedure is painful. In some cases, surgery is even required. Alternative development of scientists, based on ultrasound, is completely non-invasive and non-surgical. Ultrasound was used by researchers to increase the permeability of biological tissues to light. They turned into a kind of lens that gives optical visualization access to the organs inside. Engineers regulated the flow of ultrasound, increasing the focusing efficiency of the light at the required depth. At the same time, images that were previously inaccessible for non-invasive techniques were obtained.

Scientists have focused on working on the brain as welltissues located near the surface of the body. In the future, they plan to figure out how deep they can look into the body with their ultrasonic lens. They assure that over time, their opening will allow not to enter under the skin or into the body of the chamber. This will facilitate the study of any internal organs. And also will increase the effectiveness of the study of many diseases.
