OnePacs Workstation can display images encoded using all standard DICOM compression techniques.  In cases where the compression is lossless, there is no loss of quality.  Lossless Reversible, or lossless, compression is 100% reversible, meaning that when the image is uncompressed for display, the resulting image is exactly imaging data is bit-for-bit the same as the original (prior to compression).   Lossy compression doesn't guarantee this.  As the name implies, lossy compression is not reversible, and involves some loss in quality.  Generally, the amount of quality lost is proportional to the amount of compression appliedImages compressed with Diagnostically acceptable irreversible compression (DAIC) do not have any human-perceivable differences in image characteristics compared to images compressed with reversible/lossless algorithms. The American College of Radiology and other similar bodies in other jurisdictions have issued guidelines indicating that DAIC may be used. It is the responsibility of radiologists using such images to ensure the images are diagnostically acceptable.
