As an alternative they can also be explicitly saved to disk either as AVI, JPEG, RawDICOM or DICOM.
5-4-2 Services
The DICOM services consist of 3 different services: front end application, the connection service and
the print service. All three are implemented as separate Windows services that run as background
processes. All 3 services have dedicated user accounts they will use to log on.
All 3 users are belonging to the RW-Service Group.
They are all started automatically during system start-up and will remain active until shutdown. That
means, that requests for e.g. image storage can be accepted at all times when the system is up and
running, regardless of whether the LOGIQworks application is active or not.
The connection service is responsible for image reception and transmission in addition to accepting
requests for database queries and retrieves. It maintains logs of all studies that entered and left the
system. It can perform scheduled image transfers to remote Application Entities at all times. The
LOGIQworks front-end application issues queries to remote DICOM databases and initiates import
requests. Please note that the destination of imports is the LOGIQworks Connection Service.
The LOGIQworks Print Service is responsible for managing print job queues for one or more printers or
laser imagers. It supports several protocols of which the DICOM standard is one. Please note that the
print service is an optional component of the LOGIQworks installation.
