Q: Why does it take longer to scroll through the images the first time I load them?

A: The first time you scroll through the images, they are being retrieved from the database, pushed through the PACS web server, and sent over the internet before they finally arrive at your workstation. Once all of this happens, the images should be stored (depends on your local workstation settings) in the internet cache on your hard drive or in the memory. From here the images are accessed much more quickly.

Q: I’m looking for outside films that have been sent to PACS. Why can’t I see them from MINDscape?
