According to reports on July 28, local time of the Guardian, the latest research shows that scientists can now conduct ultrasonic scanning the human body through a sticky patch. Essence This sticky ultrasonic patch is known as a huge breakthrough in the field of medical imaging.

This kind of wearing patch is similar to stamps. It can monitor the 48 -hour image of blood vessels, digestive systems and organs, and allows doctors to understand the health status of patients in more detail than conventional instrument inspection.

In the laboratory test, the researchers used these patch to observe the shape of the heart during exercise, the expansion and contraction of the stomach during drinking, and the stretching or damage of the muscle during fitness.

The person in charge of the research team -Xuanhe Zhao, a professor at the Department of Mechanical Engineering, Massachusetts Institute of Technology in the United States, said that this kind of patch is extremely innovative for medical imaging because the existing human scanning technology can only be performed in the hospital and detected it Time is very short, sometimes only a few seconds.

Zhao Xuan congratulated the R & D idea to imagine that people do not need to go to the hospital. They can buy viscous ultrasonic patch in the pharmacy. Through smartphone programming algorithms, they can monitor whether their muscles, hearts, digestive systems, etc. have early diseases or infections during rehabilitation training during the rehabilitation training period. sign.

The biological sticky ultrasonic patch contains a series of tiny sensors that can transmit ultrasonic waves to the body through the skin, and then rebound from the blood vessels, tissue and organ, and detect the waves of bounce back by the same element in the patch. At present, this kind of patch must also be connected to the instrument to make the rebound wave into images, but researchers are developing wireless patch to match the software on the mobile phone.

Zhao Xuan congratulated: "We are working hard to develop wireless versions. Now hand -held unlimited B -ultrasound equipment has been popular. We believe that the viscous ultrasonic patch will also achieve wireless versions in the next few years."

Hospitals are very common in ultrasonic scanning examinations, but this technical limitations are large. It not only needs to be equipped with a large professional ultrasonic instrument, but also placed and positioned probe on the patients to obtain high -quality images. Therefore, the ultrasonic examination time in the hospital is very short. In addition, patients need to remain static when shooting images.

Researchers said that wireless ultrasonic patch can be worn stably on people and shooting images for several hours or even days. In addition to the signs of the early diseases of the organ, the bladder function, tumor change, and the development of the fetus in the uterus can also be monitored.

Dr. Nanshu Lu, a biomedicine engineer at the University of Texas University, said that the patch was "a major breakthrough in the field of mobile and flow ultrasound imaging."

The specific details of the patch are published in the magazine of Science.
