New Zealand scientists have performed the first-ever 3-D, color X-ray on a human, using technology that could improve medical diagnostics in oncology, cardiology, neurology and orthopedics.
Based on traditional black-and-white X-ray technology, the scanner incorporates the Medipix3RX detector chip, a particle-tracking technology developed for the CERN Large Hadron Collider. It was developed by the Medipix3 Collaboration, which comprises CERN in Geneva and 18 research institutions worldwide.
The scanner records the energy of each photon as it collides with pixels while the shutter is open, allowing for high-resolution, high-contrast pictures. It then uses computer algorithms to reveal the density of different materials, such as the percentages of water, calcium and fat in human tissue, explained Anthony Butler, a medical radiologist who worked on developing the scanner with his father, Phil Butler, a physics professor at the University of Canterbury in Christchurch, N.Z.
