Swedish researchers develop digital color x-rays

May 23, 2007 The advantages of color x-rays may not be immediately obvious but the developments in this field led by researchers at Mid Sweden University promise some exciting new possibilities for medical diagnoses much smaller x-rays doses for patients, much higher resolution and the ability to detect tumors at a much earlier stage. Digital color x-rays are based on the same advanced technology that is used when nuclear physicists look for new elementary particles. The greatest scientific challenge in constructing a color x-ray camera is to be able to shrink the large-scale detection equipment used by nuclear physicists to the microscopic format. The readout electronics for each pixel in the camera’s picture sensor must be squeezed into an area of 55 x 55 µm, and what’s more be x-ray safe.

Mid Sweden University researchers have solved these aforementioned design problems and will be presenting three dissertations in the field of digital color x-rays later this year.

Furthermore, they have shown that Medipix2 can be used to reduce the radiation dosage in dental x-rays. Industry also expects to be able to use Medipix2 technology to see the consistency of materials.

“With our digital color x-rays it will be possible to cut the radiation risk in half for x-ray examinations,” says Börje Norlin.

Using advanced computer simulations of the next generation of x-ray cameras, Mid Sweden University has also developed ways to enhance the quality of color x-rays. The cameras will have higher resolution and be able to show more colors of higher quality.

Mike Hanlon Mike grew up thinking he would become a mathematician, accidentally started motorcycle racing, got a job writing road tests for a motorcycle magazine while at university, and became a writer. As a travelling photojournalist during his early career, his work was published in a dozen languages across 20+ countries. He went on to edit or manage over 50 print publications, with target audiences ranging from pensioners to plumbers, many different sports, many car and motorcycle magazines, with many more in the fields of communication - narrow subject magazines on topics such as advertising, marketing, visual communications, design, presentation and direct marketing. Then came the internet and Mike managed internet projects for Australia's largest multimedia company, Telstra.com.au (Australia's largest Telco), Seek.com.au (Australia's largest employment site), top100.com.au, hitwise.com, and a dozen other internet start-ups before founding Gizmag in 2002. Now he writes and thinks. All articles by Mike Hanlon
