DVTk tools in service environment DVT Tools Overview Problem Faced by IO Engineers Possible Solution


RIS Emulator

This tool can be set-up to emulate basic functionality of a RIS & MPPS system.

Sending MWL responses based on the input DCM files.

Handling MPPS messages. It provides clear detail validation results. It displays the Information model created on the

fly as per input DCM files.


RIS Emulator


DICOM Network Sniffer and Analyzer Sniff the live DICOM network stream. Save DICOM stream to a capture (.cap) file by

filtering DICOM communication only between two IP addresses.

Read & analyze cap files (saved network stream).

System B0101010

1110001

System ADICOM via TCP/IP


DICOM Network Sniffer and Analyzer Evaluate/validate DICOM

communication in single/multiple DICOM association and display the overview and detail report in HTML format.

Display Service element list and Association details per association.

Saving the Service element (DICOM object) as DICOM (DCM) file.

DICOM Network Sniffer and Analyzer


DCM EditorThis tool is used for editing DICOM part-10 files and generating test data. It has the capability to: Display all DICOM attributes in tabular format with

indicating beginning & ending of sequence items. Add/delete DICOM attributes. Add/delete DICOM sequence attributes and sequence

items. Modify existing attribute values. Create a text file of the DICOM Header. Save modified dataset as DICOM part-10 file.


DCM Editor


DCM AnonymizerThis application anonymize patient characteristics and clinical information from DICOM image.


Modality Emulator• This tool can be set-up to emulate basic

functionality of all modalities: MWL Query Sending MPPS messages Send Data for Storage Handling storage commitment

• It provides you clear results (logging), with the possibility to view details results.


Modality Emulator


Storage SCP Emulator


Storage SCU Emulator


Typical scenarios in field

Problem between Modality and a RIS System The Modality sets up an association with the

RIS System and performs a RIS WLM query. The Modality received responses without any error but no patient displayed on screen.

Basic DICOM association handling seems to be OK: AE-titles, Port-Numbers, IP-addresses……


How to handle the problem Make Network capture by DICOM Sniffer. Analyze Capture in DICOM Sniffer to

investigate DICOM Communication. Check C-FIND RSP(s) saved into DCM file(s)

by DICOM Sniffer. Check validation result of C-FIND RSP and

correct DCM file Using DCM Editor. Supply correct DCM file in RIS emulator to

reproduce and investigate the problem.


Make a Network Capture


Analyze capture and save C-FIND RSP to DCM file


Check the validation result of C-FIND RSP in DICOM Sniffer


Use the result of the DICOM Sniffer and correct the problem using DCM Editor


Supply edited DCM file in RIS Emulator to reproduce and investigate the problem

When solution is verified it can be reported to RIS vendor for a bug-fix.


DCM Anonymizer Anonymization can be

performed on a CD/Directory or on a single DICOM object.

FSE can view the difference between original and anonymized dicom object.

FSE can generate the DICOMDIR of all anonymized DICOM objects.
