One DICOM viewer
for your whole lab.

Half your machines run macOS. Your viewer probably doesn't. OmniDICOM opens, reviews, measures and exports studies with one set of tools built for both platforms — and every pixel stays on the machine in front of you.

OmniDICOM volume-rendering one abdominal CT with its anterior half cut away by the scalpel, so the ribs, spine and kidneys are seen from the front.
The scalpel takes an area you draw on the view and extrudes it through the volume, so the front of the patient comes off and you look straight in — then the cut goes back and the same volume is shown as a maximum-intensity projection. Nothing is a turntable render: every frame is the CPU raycaster, on a laptop, with no discrete GPU.Every frame a real raycastLow-dose abdominal CT (L131), The Cancer Imaging Archive

What it does

Everything the study needs, on either machine.

One feature set, built once and shipped to both platforms — so the Mac in the lab is not the machine that can't open the study.

Open

Anything on the disc

DICOMDIR, CD/DVD, plain folders, multi-frame instances and the compressed transfer syntaxes that usually stop a viewer at the door. Point it at a whole drive and what it finds goes into a local archive you can search.

Review

2D reading tools

Named window presets — abdomen, angio, bone, brain, chest, lungs — and your own on the number keys, applied per panel, so two studies can sit side by side under two different windows. Zoom, pan, and cine at each run's declared rate.

Reconstruct

MPR, MIP and volume rendering

Reslice along any plane, or take a maximum-intensity projection. The scalpel extrudes an area you draw straight through the volume, so you can cut away what blocks the view — and put it back. Raycast on the CPU: no discrete GPU required.

Measure

Calibrated measurements

Length, angle, and region statistics in real units, with manual calibration for series that arrive without pixel spacing.

Transfer

PACS and DICOMweb

Query and retrieve over C-FIND / C-MOVE / C-GET, send with C-STORE, or talk QIDO-RS and WADO-RS. It also listens: point a node at it and pushed studies arrive in the viewer.

Export

Out in the format you need

Original DICOM files, PNG, JPEG and BMP stills, MP4 and WMV movies of a run or a turning volume — the image in front of you, the whole series, or every series you have open.

Process PRO

An image processing bench

Sharpen, edge-preserving smoothing, background subtraction, contrast stretch and more, stacked in the order you choose. Saving writes a new series with new instance UIDs, marked as processed — the original is never touched. The chain itself is kept against the series, so the study you reopen next month still carries the filters you left on it. Image enhancement for research and review.

Analyze PRO

Numbers out of pixels

Histograms, intensity profiles, region statistics and time-intensity curves, exportable as CSV for whatever you write next.

The actual application

Every one of those, running.

Every picture below was captured from OmniDICOM running against publicly available de-identified studies. Nothing is staged, retouched or drawn by hand.

The OmniDICOM local archive listing fifteen de-identified studies with patient code, study date, modality, series and image counts and size, and the series of the selected study in the pane below.
A folder, a DICOMDIR, a CD or a whole drive goes in; studies, series and instances come out indexed and searchable. This archive is the fifteen open-access studies used everywhere on this page — 366 instances, 588.9 MB — read and counted by the build.Local archive, built from the open-access sample set
Four panels showing three different de-identified CT studies at once: two panels of one study at a soft-tissue window, one at the CT Angio preset reading WL 300 WW 600, and one at the CT Bone preset reading WL 300 WW 1500, with all three studies listed in the rail on the left.
Three studies open at once, four panels, and a window per panel rather than per window. Two of these carry a named preset — CT Angio (WL 300 / WW 600) and CT Bone (WL 300 / WW 1500) — and each panel's readout says which one it is wearing. The other two are on the studies' own soft-tissue window.Three low-dose abdominal CT studies (L056, L114, L131), The Cancer Imaging Archive
A 57-frame coronary run playing at the 15 fps the file declares, with every other run in the study one click away in the rail.
Runs at the declared rate — each series keeps its own, so a 2x interpolated copy does not play in slow motion beside its source.Playing in real time · 57 frames · 15 fpsCoronary angiography, de-identified sample study
Biplane cerebral angiography playing with digital subtraction live on both planes: the mask frame is chosen automatically and the readout says which one it used.
Mask 3/20, subtraction on both planes, pixel-shift correction tracking every frame.Both planes, subtracted, playingCerebral DSA, de-identified sample study
A volume rendering of an abdominal CT with an area cut away from the front, looking in at the ribs, spine and kidneys.
What is in front gets in the way, so cut it off. The green outline is the lasso the operator drew; the volume behind it is removed along the view axis, and turning back looks straight in at ribs, spine and kidneys. Undo puts it back. The last beat is the same volume as a maximum-intensity projection.Every frame a real raycast · CPU onlyLow-dose abdominal CT (L131), The Cancer Imaging Archive
An abdominal CT slice with an elliptical region over the liver reading mean 67.38 and SD 31.66, a length across the vertebral body reading 53.44 mm, an angle of 43.36 degrees across the vertebra, and the calibration dialog open.
Length, angle and region statistics in the units the study calibrates to. The region over the liver reads mean 67.38, SD 31.66, area 8.4 cm²; the vertebral body measures 53.44 mm. When a series arrives with no pixel spacing, the calibration dialog takes the true length of one segment and rescales every measurement in the series.Low-dose abdominal CT (L131), The Cancer Imaging Archive
The OmniDICOM PACS search window listing fifteen studies returned by a query, with patient code, study date, description, modality, series and image counts, and the source node named in the last column.
A real query against a real node. Fifteen studies came back over C-FIND from a DICOM server and are listed with the node they came from; selected studies retrieve over C-MOVE or C-GET, and send back with C-STORE. DICOMweb nodes sit in the same list and answer QIDO-RS and WADO-RS instead.C-FIND against a DICOM server holding the open-access sample studies
The OmniDICOM export window open over an angiographic run, offering current image, current series or all opened series, and the formats JPEG, BMP, PNG, DICOM, MP4 and WMV, with the destination folder, filename prefix, image size, annotation and frame-rate settings below.
The current image, the current series or everything open — out as original DICOM files, as PNG, JPEG or BMP stills, or as an MP4 or WMV movie. The frame rate offered is the run's own: 15 fps, the same rate the transport bar behind the dialog is playing at.Coronary angiography, de-identified sample study
The chain being built on a live angiogram: edge-preserving smoothing dialled from 0.5 to 3.0, then a gentle unsharp mask, with the original held beside it the whole time.

The name is the plan

Omni means everything DICOM can do — eventually all of it.

The viewer is not a finished box. Tools land one after another, and the order they land in is decided by the people paying for it. Tell us what you are missing and why, and it gets built.

Where the pixels go

Nowhere.

Studies are decoded, rendered and processed on the machine in front of you. There is no upload step, no cloud account to view an image, and no processing queue somewhere else.

  • Uploaddoes not happen

Image processing stays local; transfers are your choice. Images leave your machine only when you send them to PACS or DICOMweb nodes you configure. Licence requests carry your key or signed token, a hashed machine id, a device label and the app version — never images, file names or patient details.

No automatic crash-report uploads. The app does not send crash reports to us. If you contact support, share only the technical details needed and remove patient information or private file paths.

Originals are never overwritten. Processed images are written out as a new series with new instance UIDs and a description that says it is processed, so a result can never be mistaken for the source it came from.

It works offline. Reading, measuring and processing need no connection at all. The licence checks in once a day when you are online, and keeps working for five days without. A machine that never reaches the internet needs a hand, so talk to us if yours is one.

The honest question

Free viewers exist. Here is what you are paying for.

No comparison table: we have not measured anyone else's software and will not pretend we have. Five things you are buying, each of them either in the build or written into the licence.

01

One feature set, not one and a substitute

The reslicing, the scalpel, the measurements, the PACS client and the export dialog are one codebase, not a Mac port of a Windows app. Everything on this page is the macOS build; the Windows build comes from the same source and is in validation now. The lab stops running one tool on the Windows box and a different, thinner one on the Mac — and stops having two sets of habits.

02

A processing bench that stays putPRO

Filters stack in the order you choose and apply to the view, so nothing is written until you say so. What you do write is a new series with new instance UIDs, and the chain is remembered against the series — the study reopens next month the way you left it, which is the difference between a filter and a method.

03

PACS and DICOMweb in the same window

Query and retrieve over C-FIND, C-MOVE and C-GET, send with C-STORE, and take pushes from a node that has been pointed at you. DICOMweb servers sit in the same node list and answer QIDO-RS and WADO-RS. No gateway to stand up, no separate retrieve tool, no exporting a study just to open it somewhere else.

04

A licence that moves with you

One machine at a time — and when the machine changes, Deactivate this computer is a button inside the app. Moving to a new laptop is two minutes on a Sunday, not a support ticket that waits for someone in another time zone to wake up.

05

Someone at the other end of the address

Tell us the tool you are missing and why, and it goes on the list; Professional subscribers go to the front of it. This is small enough that the person reading your mail is the person who writes the code — which is worth something, and is also the honest limit of what we can promise.
