Ultrasound sticker, which can image body parts for several hours
Boston: A team of scientists has miniaturized ultrasound into a sticker that can be attached outside the body to image the heart, kidneys and other organs for at least 48 hours to make better medical decisions.
The initial ultrasound sticker is the size of a postage stamp and can be applied to the abdomen and chest for continuous imaging of the stomach and lungs. Some medical conditions, exercise and other issues require a physical ultrasound for several hours. Similarly, doctors can make a better decision about the disease by observing the condition of the heart during exercise.
The research was carried out by Xuan Hai Zhao of the Massachusetts Institute of Technology (MIT) and his colleagues in what they call ‘wearable imaging’. The ultrasound sticker is made of flexible material because on the one hand it is designed to stick to the moving body and on the other hand it has to maintain the ultrasound capabilities. Thus, ultrasound implants began to provide high-quality images.
To prepare this, the scientists embedded the hard transducer in a soft adhesive. The patch also contains a hydrogel that helps absorb ultrasound waves. The hydrogel is placed between two flexible elastomers so that the entire system does not dry out.
In the experiment, 15 people were given chest, arm, neck and back prostheses and given fruit juice in a room, lifted weights, ran and cycled. During this time the sticker was continuously emitting ultrasound and the doctors noted a remarkable decrease in the dilation of the lungs, stomach, heart and central arteries.
But all the stickers were connected to a wire that sent the data to the computer that was creating the ultrasound images. This is why more research is needed to eliminate the need for wires.
Despite this, experts have welcomed this technology. Interestingly, this process eliminates the need for a certified sonographer and eliminates the need for bulky ultrasounds. In this way, it will be possible to take continuous care of the lungs of Covid-19 patients and thus revolutionize medical care.
