Robotic devices could end pain in search for signs of bowel cancer
The tiny robotic capsule known as a Sonopill is said to be the culmination of a decade of research by an international consortium of engineers and scientists.
A feasibility study has now shown that it is is technically possible to use an AI system to guide the tiny capsule inside the colon to take micro-ultrasound images.

It is hoped the technology could eventually reduce the need for painful examinations in which a semi-rigid scope is passed into the bowel.
Bowel cancer is the UK’s second biggest cancer killer and is on the rise among those under the age of 50.
The consortium has developed a technique called intelligent magnetic manipulation, which uses harmless magnetic forces to manoeuvre the device through the colon.
The AI system ensures the capsule, currently with a diameter of 21mm and length of 39mm, can position itself correctly against the gut wall to get the best quality micro-ultrasound images.
Lead researcher Sandy Cochran, professor of ultrasound materials and systems at the University of Glasgow, said: “We’re really excited by the results of this feasibility study.
“With an increasing demand for endoscopies, it is more important than ever to be able to deliver a precise, targeted, and cost-effective treatment that is comfortable for patients.
“Today, we are one step closer to delivering that through the unique combination of sensing light and sound.

Senior author on the paper, Professor Pietro Valdastri, who holds the chair in robotics and autonomous systems at the University of Leeds, said: “The technology has the potential to change the way doctors conduct examinations of the gastrointestinal tract. Previous studies showed that micro-ultrasound was able to capture high-resolution images and visualise small lesions in the superficial layers of the gut.”
