Challenge
Study volumes crush naive retrieval
Agnotic approach
Progressive and frame-level WADO-RS retrieval, tiled loading, and caching so viewers stay responsive at production scale.
DICOM / PACS
DICOM / PACS Integration
We build real medical imaging interoperability — DICOMweb (WADO-RS, QIDO-RS, STOW-RS), classic DIMSE (C-STORE, C-FIND, C-MOVE), and PACS/VNA connectivity — not just a viewer bolted onto a demo.

What DICOM / PACS integration actually involves
DICOM is the standard for medical imaging — both the file format and the network protocols. Modern imaging interop uses DICOMweb (WADO-RS to retrieve, QIDO-RS to query, STOW-RS to store) over HTTP, while established PACS still speak classic DIMSE services (C-STORE, C-FIND, C-MOVE, C-GET). Around the pixels sits an ordering and reporting flow driven by HL7 v2 ORM and ORU messages and the modality worklist.
The hard part is scale and fidelity. Studies are large, metadata is dense, and clinical safety depends on getting patient/study/series/instance identity and orientation right. We build pipelines that route studies between modalities, PACS, VNAs, and cloud storage, expose them through DICOMweb to zero-footprint viewers, and keep the HL7 order-result loop intact.

Common failure modes
DICOM / PACS pitfalls — and how we handle them
Challenge
SOP Class or transfer-syntax mismatch fails transfers
Agnotic approach
We read each conformance statement and negotiate presentation contexts explicitly, with transcoding where needed.
Challenge
Patient/study identity drifts across systems
Agnotic approach
Strict identity reconciliation on patient, study, series, and instance UIDs with an exception queue for mismatches.
Challenge
De-identification leaks PHI in private tags
Agnotic approach
Profile-based de-identification that scrubs private and burned-in tags, validated before data leaves the trust boundary.
Imaging Standards We Work With
The exact DICOM and DICOMweb surface behind production imaging interoperability.
DICOMweb (RESTful)
WADO-RS retrieval, QIDO-RS query, and STOW-RS storage over HTTP for zero-footprint viewers and cloud-native imaging apps.
Classic DIMSE
C-STORE, C-FIND, C-MOVE, and C-GET services with correct SOP Class and Transfer Syntax negotiation for legacy PACS.
Worklist & routing
DICOM Modality Worklist (MWL), study routing rules, and de-identification for research and teaching archives.
HL7 order-result loop
ORM order and ORU result messaging tied to imaging so reports and studies stay linked across RIS, PACS, and the EHR.
Where it runs
DICOM / PACS workflows we build
Cloud imaging archive
Migrate studies to DICOMweb-backed cloud storage with a VNA layer.
Web-based reading
Zero-footprint viewers for radiologists and referring clinicians.
Teleradiology
Route studies to remote readers with secure retrieval and reporting.
Imaging AI
Feed studies to AI models and write structured results back to PACS.
Patient image sharing
Give patients access to their own imaging through portals and apps.
Imaging pipelines built for real study volumes
Imaging integration breaks on scale and identity, not on opening a single DICOM file. We plan for both.

Our Process
How we deliver DICOM / PACS integration
Modality identity, study scale, and viewer performance treated as the real engineering.
1.
Discovery & modality survey
We inventory modalities, PACS/VNA, and viewers, and map the SOP Classes and transfer syntaxes actually in use.
Modality-aware
2.
Connectivity & DICOM conformance
We stand up DICOMweb endpoints or DIMSE associations and validate against each system's conformance statement.
Conformance-checked
3.
Build & test
Study routing, retrieval, and viewer integration validated against real and synthetic studies at production sizes.
Load-tested
4.
Go-live & monitoring
Production rollout with transfer monitoring, storage-commitment tracking, and failed-study alerting.

DICOM interop — protocol & when we use it
How we choose between DICOMweb and classic DIMSE.
| Service | Protocol | Use | Notes |
|---|---|---|---|
| WADO-RS | DICOMweb / HTTP | Retrieve studies | Preferred for web viewers and cloud apps. |
| QIDO-RS | DICOMweb / HTTP | Query metadata | Search studies/series/instances by attributes. |
| STOW-RS | DICOMweb / HTTP | Store studies | HTTP-native ingest from apps and devices. |
| C-STORE / C-MOVE | DIMSE / TCP | Push / pull studies | Still the backbone of established PACS. |
| MWL | DIMSE / TCP | Modality worklist | Feeds patient and order context to modalities. |
We negotiate SOP Classes and transfer syntaxes against each system's DICOM conformance statement.

We get patient/study/series identity and orientation right, because imaging errors are clinical errors.
Frequently Asked Questions
A DICOMweb-to-viewer integration can land in weeks, while a full PACS/VNA connectivity and routing program typically runs 2–4 months. The timeline depends on how many modalities and legacy systems are involved and how quickly we can validate against each conformance statement.
