5-22 Section 5-4 - Software Theory
5-4-2 Services
(cont’d)
The Database and Connection Services are integral parts of a LOGIQworks installation.
In addition to the Storage SOP Class support for networking, LOGIQworks also supports the Media
Storage Service Class for the Interchange of images as a File Set Reader (FSR) and File Set Creator
(FSC). FSR is a standard feature and FSC is an optional feature.
5-4-3 Functional Definitions of Application Entities
The Application Entity of the LOGIQworks Connection Service acts as an SCU for the verification,
storage, and storage commitment SOP classes and as an SCP for verification, storage, query, retrieve,
and storage commitment SOP classes.
The Application Entity of the LOGIQworks front-end application acts as an SCU for the query and
retrieve SOP classes.
The Application Entity of the LOGIQworks Print Service acts as an SCU for the basic gray scale and
color print management meta SOP classes, and optionally the Print Job and Basic Annotation Box SOP
classes.
5-4-4 Number of associations
The LOGIQworks Connection Service supports multiple associations both as an SCU and SCP. By
default the maximum number of simultaneous associations that the Connection Service will support as
an SCP is 4.
Please refer to RadWorks 6.0 Installation Guide, page 54 , Configuring teleradiology section, Setting up
the Connection Service.
When receiving images or processing query and retrieve requests as an SCP the Connection Service
will start a new thread for each association that is being handled. As an SCU the Connection Service
also supports multiple associations, for instance to verify a remote destination and simultaneously send
images to a storage SCP.
The LOGIQworks front-end application supports multiple associations as an SCU for query and retrieve
to different SCPs. Multiple queries and/or retrieves to the same SCP will be performed sequentially.
The LOGIQworks Print Service will queue multiple print jobs such that it only establishes one
association as an SCU at a time when it manages multiple laser imagers via DICOM.
The LOGIQworks DICOM services do not support asynchronous operations and will not perform
asynchronous window negotiation.
5-4-5 Auto-routing
LOGIQworks allows image transfers to be scheduled for specific times and has mechanisms for retrying
a transfer in case that a transfer failed at an earlier time. After a configured number of unsuccessful
attempts LOGIQworks will mark the transfer as failed. The LOGIQworks system keeps a log of transfers
that is viewable by the user. The log indicates the status of transfers.
LOGIQworks provides full (level 2) conformance as SCP of the Storage SOP class. This means that
upon sending an image received via DICOM on to another DICOM compliant system it will send out all
attributes that it received (this includes private attributes from other vendors).
Please refer to RadWorks 6.0 Installation Guide, page 54 , Configuring teleradiology section, Setting up
auto-routing.
