摘要

固有噪声和量子噪声构成了医学X光影像系统的干扰噪声。它们在统计规律上分别是依从高斯分布和泊松分布的随机空间波动。本文从理论上推导出了基于小波变换原理的医学X光影像的固有噪声抑制和消除处理中的最优滤波阈值选择。通过对实际CT影像的消噪处理应用

实现了基于最小均方误差原理的医学X光影像的滤波处理。

Abstract

Disturbance noises in medical X-ray imaging systems consist of inherent and quantum noises

which obey random Gauss and Polsson distributions

respectively. This paper theoretically provided an optimum threshold selection method for medical X-ray images filter. Through practical process of CT images

medical X-ray images filter based on minimum even-square error has been accomplished in this work.
