No more mismatched studies
When the modality takes the accession number from the worklist, the study, the order and the report link automatically. Manual entry is where wrong-patient and unmatched studies come from.
DICOM MODALITY WORKLIST · BANGLADESH
DICOM Modality Worklist (MWL) for Radiology
Modality Worklist is the DICOM service that sends the day's scheduled examinations to the modality. The technologist picks the patient from a list instead of typing a name and ID at the console, so every study arrives in the PACS with the correct demographics and accession number and matches its order and report automatically. EMSL's MWL server is part of its PACS and RIS, and it runs with the modalities of hospitals and diagnostic centres across Bangladesh.

CAPABILITIES
What the MWL platform does
Explore the core capabilities, then see how they fit into everyday work.
- ✓MWL SCP (C-FIND on the Modality Worklist information model) for any DICOM-conformant modality
- ✓Scheduled procedure steps generated from RIS or HIS orders and appointments in real time
- ✓Patient name, ID, date of birth, sex, accession number, requested procedure and scheduled station in every entry
- ✓Per-modality filtering by station AE title, modality type and date, so each unit sees only its own list
- ✓Walk-in and emergency patients appear on the worklist the moment they are registered
- ✓Works with a third-party RIS or HIS through HL7 orders when EMSL supplies only the imaging side
- ✓Log of every worklist query per modality for troubleshooting
Built around your daily work
Any modality, any vendor
Modality Worklist is a standard DICOM service. CT, MRI, CR, DR, ultrasound and mammography units from any manufacturer query the same server.
Faster patient throughput
Technologists select instead of type, so examinations start sooner and the console shows the right procedure for each patient.
Configured with your modality vendor
EMSL's engineers register AE titles, addresses and ports on both sides with the vendor's service team and verify the worklist on the console before go-live.
IN DEPTH
MWL in detail
How Modality Worklist works
The RIS or HIS creates an order and an appointment. EMSL's MWL server turns it into a scheduled procedure step: patient identity, accession number, requested procedure, modality type and the station that should perform it. When the technologist presses the worklist button on the console, the modality sends a DICOM C-FIND query to the server, typically filtered to its own AE title and today's date, and receives the matching entries. The technologist selects the patient, the modality copies the demographics and accession number into the study, and the images later sent to the PACS carry them. The RIS sees the study arrive, matches it to the order by accession number, and moves it to the reading worklist.
Configuring a modality for MWL
On the server, the modality is registered with its AE title, IP address and port. On the modality, the worklist server is registered the same way, usually under a service menu, and the query filter is set — most sites filter on the modality's own station AE title and the current date. A test query from the console confirms the connection. EMSL's engineers do this together with the modality vendor's service team during installation.
Common problems and how they are fixed
An empty worklist almost always means a filter mismatch: the station AE title configured on the modality differs from the one in the order, or the modality's clock is on the wrong date. A wrong patient chosen at the console is corrected in the RIS, which re-links the study to the right order without re-scanning. A modality that cannot reach the server at all is a network or firewall question, and the server's query log shows whether the request arrived.
PLAN YOUR PROJECT
Start with your workflow.
A useful evaluation starts with the people, systems and handoffs in your organisation. Use these points to shape the conversation.
YOUR MWL DISCUSSION CHECKLIST
Bring the details that matter.
- Confirm which modalities support DICOM Modality Worklist.
- Prepare AE titles, network details and vendor contacts.
- Review patient identifiers, accession numbers and procedure mapping.
Walk through a real scenario
Choose a typical day in your department. Follow each handoff in the demo and check what each team needs to see or do.
Confirm the fit
Review existing systems, required interfaces, access roles and reporting needs. Agree what needs configuration or further validation.
Define the rollout
Discuss deployment, data migration, staff training and support. Agree the scope and acceptance checks before setting a go-live plan.
FAQ
A few things you may want to know.
Common questions about MWL, integration and day-to-day use.
Have a different question?Do we need Modality Worklist if we already have a PACS?
If technologists type patient details at the console, yes. MWL removes that typing and is the single biggest fix for mismatched and unmatched studies in a PACS.
Which modalities support MWL?
Nearly all CT, MRI, CR, DR, ultrasound and mammography units sold in the last fifteen years. The modality's DICOM conformance statement lists it as Modality Worklist SCU.
Can MWL work with our existing HIS?
Yes. Orders from a third-party HIS or RIS reach the EMSL MWL server through HL7, and the worklist entries are generated from them.
What about walk-in patients?
They are registered in the RIS or HIS in the normal way and appear on the modality's worklist immediately.
