At the hospital all images are viewed as uncompressed. However when you’re accessing PACS remotely using compression helps speed up retrieval of images over slower home DSL and Cable connections.

JPG COMPRESSION
The manner in which images are effectively stored reduces the use of storage
space as well as reducing the traffic on the network.
The compression of the images to be stored can be performed in
three ways:

1. Compressed: Using JPG compression, the user can decide
   how much loss to introduce and make a trade-off between file
   size and image quality.

2. Lossless Compression: With lossless compression, every
   single bit of data that was originally in the file remains after the
   file is uncompressed. All of the information is completely
   restored.

3. Lossy Compression: Lossy compression reduces a file by
   permanently eliminating certain information, especially
   redundant information. When the file is uncompressed, only a
   part of the original information is still there (although the user
   may not notice the difference).
