New diagnostic techniques offer better view of the inside

Researchers made a computer-monitored capsule that can travel through the body searching for signs of illness, and state-of-the-art computer science to help surgeons pinpoint the exact position of a diseased cell.

Researchers created of a new form of IT-based surgery that can make the inside of a patient's body transparent on a screen during an operation. The surgery uses technology that transforms X-rays and ultrasound into three-dimensional (3D) maps displayed on a screen that surgeons can use to navigate within the body when performing keyhole surgery.

The technique will allow surgeons to use keyhole surgery more often in preference to traditional surgery, as it will be far less stressful for patients and will mean less time in hospital.

In another revolutionary medical technique, a capsule , when swallowed, moves through the digestive system detecting illness and diseased cells. Such capsules already exist, but the version being developed by SINTEF offers an improvement because it can be monitored and controlled by a computer system that allows the capsule to stop or go into reverse when something in the body needs closer attention.

The capsule will have sensors that are based on ultrasound, spectroscopy and possibly biosensors. It will also be able to collect tissue samples. Moving through the digestive system, the capsule will have the capacity to pick up early warnings of serious diseases such as colorectal cancer, thus possibly saving many more lives than with the existing methods of diagnosis.
