MESI mCONNECT v1.2 has passed the U.S. Department of Veterans Affairs’ DICOM validation testing. The tested configuration (model MTABSYS, the MESI mTABLET system) is listed in the July 2026 VistA Imaging Approved DICOM Modality Interfaces report as an Evidence Creator (Encapsulated PDF) interface.
For VA facilities evaluating point-of-care diagnostics, that matters more than a typical vendor integration claim. The interface was not tested by MESI and reported to the VA; it was tested by the VA, against the VA’s own specification, and published by name, model, and software version.
Key facts

What VA DICOM validation testing involves
The VA operates a remote conformance test suite. A vendor’s device connects to a VA test system over the internet, and the DICOM objects it produces are checked against the requirements published in the Joint VA/DoD DICOM Modality Conformance Requirements.
Conformance testing is unusually unambiguous. Either the objects a device produces meet the specification or they do not. There is no partial credit and little room for interpretation. That is precisely what makes third-party conformance results useful as evidence, and also why they are narrow. The suite examines DICOM behaviour. It is not a regulatory clearance, and it says nothing about clinical performance.
What an Evidence Creator (Encapsulated PDF) interface does
In DICOM, an Evidence Creator is a device that generates evidence objects: results, reports, measurements, rather than acquiring images the way a CT or X-ray unit does. Encapsulated PDF describes how the report travels: the PDF is carried inside the DICOM object, intact.
In practice, that is the difference between a MESI mTABLET ABI or ECG report arriving in the receiving system as a real, text-bearing document filed against the correct patient and study, and arriving as a flattened picture of a report or, worse, as a printout somebody has to scan back in. The text stays selectable and searchable. The patient and study identifiers travel with it. Nobody retypes anything.
“This milestone reflects our continued focus on scalable, reliable and standards-based connectivity. Healthcare organisations need diagnostic solutions that can fit into their existing digital environments and make relevant information available where it is needed. The successful validation of MESI mCONNECT v1.2 provides additionalconfidence in the technical foundation we are building for connected diagnostic workflows.” Jan Kruljac, MESI mCONNECT Project Manager at MESI
What this means for VA facilities
The listing clears a prerequisite rather than opening a door but clearing it removes a real unknown. For a VA medical center weighing a new point-of-care diagnostic device, DICOM conformance is normally an open question until somebody tests it. Here it has already been tested centrally, against the specification the VA itself publishes, and the result is on the record.
What remains is local. Facilities are still required to complete their own quality review of the images a device produces, and to file the results with the National VistA Imaging Project Office, before it can be placed into clinical use. The listing does not shorten that process or substitute for it. It means the facility is reviewing a device whose interface behavior is already documented rather than assumed.
Facilities evaluating the MESI mTABLET should start with their imaging service and biomedical engineering teams, who own the local quality review. Reference the July 2026 listing by manufacturer, model, and software version.
Beyond the VA
The behavior the VA tested is the behavior every receiving system sees. Any PACS, imaging archive, or EHR that accepts DICOM applies broadly similar expectations to the objects it is sent, so the VA’s published result is a documented reference point for IT teams outside the VA as well.
Scope and limitations
Inclusion in the VA report does not constitute endorsement by the U.S. Department of Veterans Affairs. The VA states that its list indicates only whether a product has passed internet-based validation testing, and that the process does not indicate how well a product will work operationally, either within the VA or elsewhere.
The listing applies to this specific product configuration, software version, and tested functionality. It should not be read as validation of every function within the broader MESI mTABLET system.
The report is reissued periodically and its contents change over time. The VA may revise its testing requirements at any point, and future MESI software revisions may require re-validation. The details above reflect the July 2026 edition.
