For several decades, X-ray test results have always shown black and white images. Now, a new method is bringing colors in X-ray results to improve medical diagnosis.

The method has been developed by scientists in New Zealand. According to the European Organization for Nuclear Research, CERN which contributed to the project, the new X-ray imaging device was based on the standard X-ray technology but incorporated with particle-tracking tech. The final product has been dubbed Medipix that works like a camera in detecting and tracking every sub-atomic particle that collides with the pixels.

"This color X-ray imaging technique could produce clearer and more accurate pictures and help doctors give their patients more accurate diagnoses," stated CERN, quoted Phys.org.

Medipix is a family of chips designed to detect particles. It can capture images with high resolution and high contrast and is free of noises -- factors needed by many imaging applications. There are several chips that have been produced since 1997.

1. Medipix1 was developed in 1997 that directly charges the conversion of photons to reduce image blurring.

2. Medipix2 was created in 1999 with high spatial and high contrast imaging results.

3. Medipix3 was formed in 2005 that has a size of 130 nanometers. Similar with Medipix2, the third generation captures images based on the number of particles that hit the pixels, but Medipix3 can overcome the adverse effects of fluorescence and charge diffusion.

4. Medipix4 was built in 2006 and has two different chipsets. One of these chips is compatible with X-ray imaging and medical CT scans.

The colored X-ray device has been tested to view anatomical parts of the body. So far, the scans displayed differences among bones, muscles, and cartilages, and were able to bring the position and sizes of malignant tumors.
