Matching Sequence Protocols

To automatically lay out studies in the viewports, sequence protocols contain matching rules that define the criteria used by InteleViewer to determine whether the sequence protocol should be applied to the study.

For each sequence protocol that you create, you can add as many matching rules as required. This is useful in an InteleOne XE or multi-site IntelePACS environment where studies from site A, for example, have procedure codes and studies from site B have no procedure codes. In this case, you may want to add a Uniform Study Descriptor matching rule that defines studies from site B with a specific modality and body part to be matched, but may also want to match a specific procedure code that defines studies from site A.

When InteleViewer tries to determine whether the sequence protocol should be applied to the study, it uses several matching methods to compare the attributes of the study with the criteria in the matching rule. If InteleViewer does not find a match, it continues through the matching rules until a match is found or until it no longer finds any rules, in which case it moves on to the next sequence protocol in the Protocol Library. If a specific sequence protocol cannot be found for the study, then InteleViewer does not apply a sequence protocol to the study.

As a general rule, the more specific a sequence protocol, the more likely it is to be selected. Once InteleViewer applies the most relevant sequence protocol, reading steps are realized based on the available views.

If your workflow uses grouped procedures, and you open an order with multiple procedures from the worklist, InteleViewer matches a sequence protocol to the most recent procedure in the group. For example, if you open an order comprised of three procedures, chest, abdomen, and pelvis, where the chest procedure is the most recent procedure in the group, InteleViewer matches a CT sequence protocol.
