For practitioners deploying store-and-forward telepathology systems, optimization methods such as image compression need to be studied.
To determine if Joint Photographic Expert Group (JPG or JPEG) compression, a glossy image compression algorithm, negatively affects the accuracy of diagnosis in telepathology.
Double-blind, randomized, controlled trial.

Compression of raw images using the JPEG algorithm.
Image acceptability, accuracy of diagnosis, confidence level of pathologist, image quality.
There was no statistically significant difference in the diagnostic accuracy between noncompressed (bit map) and compressed (JPG) images. There were also no differences in the acceptability, confidence level, and perception of image quality. Additionally, rater experience did not significantly correlate with degree of accuracy.
For providers practicing telepathology, JPG image compression does not negatively affect the accuracy and confidence level of diagnosis. The acceptability and quality of images were also not affected.
对于部署存储转发式远程病理学系统的从业者而言，需要研究诸如图像压缩等优化方法。
确定联合图像专家组（JPG或JPEG）压缩这种有损图像压缩算法是否会对远程病理学诊断的准确性产生负面影响。

使用JPEG算法对原始图像进行压缩。
图像可接受性、诊断准确性、病理学家的置信水平、图像质量。
未压缩（位图）图像和压缩（JPG）图像之间的诊断准确性无统计学显著差异。在可接受性、置信水平以及图像质量感知方面也没有差异。此外，评分者的经验与准确性程度无显著相关性。
对于从事远程病理学的人员来说，JPG图像压缩不会对诊断的准确性和置信水平产生负面影响。图像的可接受性和质量也未受影响。
