Weihua Wang · Chinese Medical Equipment Journal · 2010
Objctive To remove noise and improve the quality of images for digitized X-ray images.Methods A simple and effective filter was designed based on Wiener optimality criterion,and it is adopted to filter digitized X-ray images.Results The result of contrast to Median fiter indicates that Wiener filter can remain images in detail while remove added noise.Conclusion This filter is effective for all digitized X-ray images and detector including CR,DR and DSA imaging,and has high practicability.
