Tag Filters
NOTE: If you delete a tag, tag filters rules that reference this tag may
also be deleted. Please exercise caution when deleting tags.
A tag filter is a set of rules used to apply processing selectively to some, but not all incoming
DICOM data. The filter divides the data into two bins - those that pass the filter, and those
that do not. Only the data that passes through the filter will be processed.
Tag filters are used in five AquariusNET features: auto series assignment, auto filming, auto
prefetch, auto routing, and advanced processing. To use tag filters with these functions, first
create tag filters from the "Tags" page, and then go to the relevant sub-sections under
Manage Workflow in the navigation panel.
A tag filter rule consists of a DICOM tag, a comparator, and a tag value. There are four
comparators: “is”, “is not”, “contains”, and “doesn’t contain”. The tag input value is case
insensitive. The Logical operator AND will be applied between any and all pairs of rules
within the filter.
The steps required for setting up tag filter include creating tag filters and associating filters
with user groups. Filtering is accomplished by comparing the values of certain DICOM tags in
the incoming data with expected values as specified in the tag filter.
Default Tag Filters
The AquariusNET Server provides a number of default tag filters related to Advanced
Processing. These can be used to send studies to different DICOM servers based on the body
part, modality, or Clinical Protocol.
The Tag Filter Manager
To manage filters, click on the Manage Workflow link in the navigation panel, and then click
on the Tag Filter link to display the "Tag Filters" page, as shown in Figure 8.3.
