摘　　要：为了优化PET图像,需要根据PET图像的成像特点和临床工作的实际需要设计去噪算法。本文通过对于正电子图像后处理去噪方法的回顾,分析其具有的局限性并提出相应的对策,特别针对多尺度分析法,提出如何在提升PET图像处理品质的基础上减少人工干预,简化算法结构,缩短处理时间。For PET images, it is necessary to design a good multiscale analysis denoising method, the actual needs and the characteristics of positron emission tomography image should be taken into consideration. This paper given a brief review of positron emission tomography image post-processing denoising methods, the limitations of the methods were analyzed, then countermeasure strategies were addressed. Especially for multiscale analysis, it is very important to lower the human intervention, to streamline the algorithm structure and to reduce processing time.
