The X-ray exposure of hepatic MDCT (Multidetector-Row Computed Tomography) images threatens human health. In this paper, the 3D adaptive median filter with local averaging is optimized to improve the image quality of low dose hepatic MDCT images. The modified strategy is designed according to the subtle texture of a hepatic tumor. Filtering experiments are(More)
The risk of X-ray exposure will increase when applying the 3D-CT methods such as MDCT. To decrease this risk it is better to lower the dose-level of X-ray, but it reduces the resolution of obtained image and causes negative effect on imaging diagnosis. We think that 3D-filtering methods will recover the reduction. In order to obtain a better filtered(More)
