6.1 Introduction

This section of the DICOM Conformance Statement specifies the compliance to DICOM

conformance requirements for the relevant Networking features on this GEHC product. Note

that the format of this section strictly follows the format defined in DICOM Standard PS 3.2

(Conformance). Please refer to that part of the standard while reading this section.

The ModalityWorklist option for LightSpeed allows a user to query for and display DICOM

modality worklist information from a remote hospital or radiology department information system

computer. For example, a user may wish to query for all procedures scheduled to be performed

on the scanner. In this situation, ModalityWorklist is providing the DICOM C-FIND service as a

service class user (SCU).

6.2 Implementation Model

All DICOM functionality provided by the ModalityWorklist feature is logically provided by the

Worklist Server DICOM AE. The Worklist Server DICOM AE is commanded to perform DICOM

modality worklist query services through the use of the LightSpeed user interface.
