Biological Imaging with X-rays and Medipix detectors. The single quantum counting pixel device Medipix2 serves as imaging area. Detectors Medipix2 do not suffer from so called dark current (noise) and work in non-limited dynamic range. These features of detectors confer high quality and high contrast of final images.The radiographic imaging with detectors Medipix2 represents non-invasive and non-destructive method of investigation.
