Notification about Worklist Availability

• We proposed a push model of MWL at the last meeting of DSC in Munich. But, it was rejected.

• We still need a mechanism that can trigger a modality to pull a specific worklist.– Poling is one of the solutions, but it may cause the

network congestion.– An RIS terminal is usually put closely by the moda
