6.6 CONFIGURATION
The ModalityWorklist feature is configured by GEHC Field Service engineers. The DICOM
configuration items below are configurable or re-configurable by a Field Service Engineer and
are not accessible by users through the LightSpeed user interface.
6.6.1 AE Title/Presentation Address Mapping
ModalityWorklist allows for the configuration of the following parameters that pertain to the
remote AE.
• Remote AE (HIS/RIS) IP address – IP address used to contact the remote AE
• Remote AE (HIS/RIS) IP port – IP port used to contact the remote AE
These parameters define where worklist queries will be directed. Configuration of these
parameters is performed by GEHC Field Service engineers using the ModalityWorklist
installation facilities.
6.6.2 Configurable Parameters
The following parameters are configurable for the DICOM Worklist Server AE:
• Local (Worklist Server) AE Title (automatically set to host name of scanner)
• Local IP address
• Local IP netmask
• Local IP gateway
The following parameters are configurable by changing their values in the configuration file
/usr/g/config/WLdcm.cfg. Note that these parameters typically need not be changed.
Furthermore, no support is provided for retaining changed settings: the values will require
changing again after a system software upgrade.
• Implementation UID
• PDU size
• Association time-out period
• Session time-out period
• C-FIND time-out period
6.7 Support of Extended Character Sets
ModalityWorklist will support only the ISO_IR 100 (ISO 8859-1:1987 Latin alphabet N 1.
supplementary set) as extended character sets.
