Digital CR medicine radiation image is in doctor's favor and has became medicine imaging technology new hot spot because of its high gray contrast
powerful computer disposal function
little radiation dosage
non-film diagnosis
different area consultation. But degradation of digital X-ray medical image such as low contrast and blurring during radiographic imaging
caused by complexity of body tissue and effects of X-ray scattering and electrical noise etc.
can worsen the results of analysis and diagnosis. So it is usually needed that CR medicine image is enhanced to improve its vision quality
and easy to doctor's more accurate diagnosis. The general enhancement algorithms over enhancing the contrast and lose image details
aiming at the defects
an enhancement algorithm for CR image is proposed based on the ratio of deviation to mean of domain. The arithmetic enhance CR image edge details by adjusting factor K based on the ratio of deviation to mean of domain of CR image. Experiment results demonstrate that the algorithm enhances CR image detail and CR image enhanced has good visual effect
the adaptive enhancement method is fit for CR medicine image. (2012) Trans Tech Publications
