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.
