Noise Reduction for Computed Tomography using Multi-Resolution Total Variation Minimization
碩士 === 中臺科技大學 === 放射科學研究所 === 98 === Computed tomography (CT) produces high-resolution images, and had been widely used in clinical examination. However, quantum mottle will decreased the image contrast and resolution, when the tube current (mAs) is insufficient. In this study, a multi-resolution to...
