"Remote" versus "Local" Filtering
The search criteria you set up in the Utility -> Connectivity -> Service page are used in "remote"
filtering. When you press the Query button on the Worklist screen, the criteria becomes part of the
DICOM message exchange between the LOGIQ E9 and the Worklist service. The service returns only
those entries that match all of the search criteria.
In contrast, "local" filtering occurs "on the fly" on the patient data already queried, listed and stored on
the LOGIQ E9. Local filtering occurs every time you enter a value in one of the fields above the list on
the Worklist screen, such as Patient ID. The displayed list gets filtered progressively for each selection
you make or character you enter.
example: For a Worklist with dozens of entries, select Accession Number as the Search Key and enter
"1." The list is filtered to display only those entries whose Accession Number starts with "1." Now enter
"2" after the "1." The list is filtered again to display only those entries whose Accession Number starts
with "12."
Table 3-20
Local filtering DOES NOT generate any DICOM traffic between the LOGIQ E9 and the service. It acts
only upon the list already on the LOGIQ E9. This local list does not constitute actual patients and
exams on the LOGIQ E9. Creation of patients and exams does not occur until you select one or more
entries on the list and press Transfer. But, there is a twist; if you enter a value in one of the fields
above the list on the Worklist screen, and then press Query, you are doing "remote" filtering again.
The filter comprises the search criteria you set up in the Utility -> Connectivity -> Service page, plus
whatever you entered in the field(s) above the list on the Worklist screen.
Continuing the Accession Number example: Enter "12" and press Query. The query returns only
exact matches.
