Further discussion users would site can have one or multiple Departmental PACSs (e.g. Radiology, Cardiology) and each Departmental PACS can have one or multiple nodes.

query process

At CHB, BWH and BIDMC there is a single gateway for query. At MGH, it is a multi-node PACS.

Policies and Procedures for PACS access at each institution

• Continued discussion about position the C-moves in a friendly way with the Radiology PACS. For each AE address it is "sufficient' to pull images between X time and X time on X day of the week at a rate of XX images/10 minutes per thread with a limit of X threads. Jesse suggests having some sort of dynamic parameter that will regulate the pulls by a factor that is responsive to the busy-ness of the PACS such as a ratio of 5x the pull return time before the next pull could be sent. Shawn points out that the limit to the number of threads in fact may accomplish this goal. This plan is simple and will be easier to test, build trust in and adjust as needed both increasing and decreasing parameters per site. Shawn expressed concern about complex algorithms as they are highly prone to fail.
