Statistical and deterministic properties of median filters are briefly discussed and their inherent advantages as a prospective tool in scintigraphic data processing are pointed out. The ability of median filters of suppressing impulse noise while the edge-like features of an image are preserved, is demonstrated on phantom data. The residual high-frequency noise remaining after median filtering can be subsequently reduced by standard smoothing procedures. A simple algorithm, made up of the superposition of a median and an averaging filter, is presented and shown to be a promising candidate in the quest for fast and easy-to-implement processing routine.
简要讨论了中值滤波器的统计特性和确定性特性，并指出了其作为闪烁扫描数据处理中一种潜在工具的固有优势。在体模数据上展示了中值滤波器在保留图像边缘特征的同时抑制脉冲噪声的能力。中值滤波后残留的高频噪声随后可通过标准平滑程序降低。提出了一种由中值滤波器和平均滤波器叠加组成的简单算法，结果表明，在寻求快速且易于实现的处理程序方面，该算法是一个有前景的选择。
