摘要: 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 image quality low dose images. modified strategy designed according subtle texture a tumor. Filtering experiments are based on phantom different levels and clinical ones certain level. Radiologists’ visual evaluation voxel value profiles show that x-ray can be reduced 60% at least without compromising diagnostic
