3-9-4-5 How to Setup and Use a DICOM Worklist Service (cont'd)
"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 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 . 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.
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 3-18
Local filtering DOES NOT generate any DICOM traffic between the and the service. It acts only upon
the list already on the . This local list does not constitute actual patients and exams on the . 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.
