London scientists have created a robotic capsule that can take images inside the colon. This device known as Sonopill could eventually replace the invasive procedure of endoscopy to detect cancer.
The Sonopill is the culmination of a decade of research by an international consortium of engineers and scientist. Based on the principle that magnets can attract and repel one another, a robotic arm passes over the patient and interacts with a magnet inside the capsule, guiding it through the colon. An AI system makes sure the capsule is positioned correctly against the gut wall to get the best quality images. The advantage to this system is, it’s harmless to the patient and doesn’t require a physical connection between the robotic arm and the capsule. Read the full article to learn more.
