Based on the principle that magnets can attract

The consortium has developed a technique called intelligent magnetic manipulation.An artificial intelligence system (AI) ensures the smooth capsule can position itself correctly against the gut wall to get the best quality micro-ultrasound images.According to the study published in the Journal of Science Robotics, it is technically possible to guide a tiny robotic capsule inside the colon, part of the large intestine, to take micro-ultrasound images. Previous studies showed that micro-ultrasound was able to capture high-resolution images and visualise small lesions in the superficial layers of the gut, providing valuable information about the early signs of disease.The magnetic forces used are harmless and can pass through human tissue, doing away with the need for a physical connection between the robotic arm and the capsule. This discovery has the potential to enable painless diagnosis via a micro-ultrasound pill in the entire gastrointestinal tract," he added. The capsule houses a micro ultrasound transducer, an LED light, a camera, and a magnet..The Sonopill is a small capsule with a diameter of 21mm and length of 39mm, which the engineers say can be scaled down. The feasibility study also showed should the capsule get dislodged, the AI system can navigate it back to the required location.The feasibility tests were conducted on laboratory models and in animal studies involving pigs.Professor Pietro Valdastri, the senior author of the paper, said, "The technology has the potential to change the way doctors conduct examinations of the gastrointestinal tract.

Based on the principle that magnets can attract and repel one another, a series of magnets on a robotic arm that passes over the patient interacts with a magnet inside the capsule, gently manoeuvring it through the colon.""With this study, we show that intelligent magnetic manipulation is an effective technique to guide a micro-ultrasound capsule to perform targeted imaging deep inside the human body.Micro-ultrasound images also have the advantage of being better able to identify some types of cell change associated with cancer.Engineers have discovered a device which could replace the need for patients to undergo an endoscopic examination, a nonsurgical procedure used to examine China Vacant capsule Manufacturers a persons digestive tract.A very small flexible cable is tethered to the capsule which also passes into the body via the rectum and sends ultrasound images back to a computer in the examination room.Diseases of the gastrointestinal tract account for approximately 8 million deaths a year across the world, including some bowel cancers which are linked with high mortality.In the place of a semi-rigid scope which was used to be passed into the bowel, leading to an invasive procedure that was painful will now be replaced by a device called Sonopill. The platform is able to localise the position of the Sonopill at any time and adjust the external driving magnet to perform a diagnostic scan while maintaining a high-quality ultrasound signal
