A new 3D gamma radiation imaging system could improve the diagnosis of lung disease and aid research into its effect on the body. A team of doctors, scientists and engineers at Southampton University has developed the system, which produces 3D computer images of the lungs, and has begun using it to study different conditions. The system combines a model of the lungs created using X-ray computed tomography (CAT scanning), with a 3D map of how a radioactive aerosol spreads through the lungs once it is inhaled, which is built using two gamma radiation detectors.
