PROFESSIONAL · INCLUDED IN THE 14-DAY TRIAL

Go further with Professional.

Denoise for CT, MR and X-ray, plus filter chains and quantitative analysis, on your own computer.

01Denoise

Denoise for CT, MR and X-ray.

Click Denoise to reduce noise across a CT, MR or X-ray series, starting with the image on screen. Click again for the original. Your DICOM files are never changed.

Same slice, Denoise off and on

CT slice at W400/L40, whole slice, Denoise off
Denoise off
CT slice at W400/L40, whole slice, Denoise on
Denoise on

Two captures from OmniDICOM of the same CT slice at window 400 / level 40 (W400/L40): Denoise off and on. The slider is part of this web page, built from the two captures; in the app you click Denoise again or press and hold Hold to compare. Images are 8-bit display captures, not HU data.

In the 2D view, measurements, ROI statistics, histograms, profiles and exports use the denoised image, and Statistics, Histogram, the profiles and Particles label their results “denoised image”. MPR, 3D, time-intensity curves and slice projections use the original pixels.

For research and education only, not for diagnosis. This applies equally to denoised and processed images.

Sample: CT Colonography (ACRIN 6664), TCIA, CC BY 3.0 — credits

Denoise is noise reduction, not image generation: it estimates the noise in each slice or X-ray image and removes it.

  • CT and MR series and X-ray images (CR, DX, DR, RG); not mammography
  • Runs on your own computer; no image is uploaded
  • Mac: macOS 14 or later
  • Windows: the graphics card where available, otherwise the processor
  • Can be saved for the series on this computer, like other processing
  1. Click Denoise
  2. Click again: the original
  3. Click again: Denoise on
  4. Scroll denoised slices
Real app capture on a CT series: Denoise on, off and on again, then scrolling through denoised slices. The wait for the first run is cut from the clip.

02Process

Process: filters in your order.

Chain up to eight filters with typed values, save presets, apply them to selected series, and hold to compare without Denoise and filters.

  • Sharpen – unsharp mask with Threshold
  • Sharpen (3×3)
  • Local contrast (CLAHE)
  • Edge-preserving smoothing
  • Vessel and small-structure enhance, including dark structures
  • Subtract background, dark or light
  • Gamma and contrast stretch
  • Apply, or Save & Apply

Apply shows the result on screen; Save & Apply also saves it for the series on this computer. Filters change the displayed image, not the values you measure: measurements read the stored values, or the denoised values while Denoise is on.

  1. Tick Denoise, then Sharpen – unsharp mask
  2. Type Radius, Amount, Threshold
  3. Apply
  4. Press and hold Hold to compare
  5. Save & Apply
Real app capture: Denoise and Sharpen – unsharp mask (Radius 1.5, Amount 0.8, Threshold 6), Apply, Hold to compare, then Save & Apply. The processing wait is cut.

03Analyze

Analyze: numbers you can take with you.

ROI statistics, histograms, line and Z profiles, time-intensity curves, particles and the ROI manager. Copy the data or save CSV.

A time-intensity curve compares two or more series as timepoints. Within one run, Z profile follows a region across its frames.

Length, ellipse and polygon drawing tools are included in Basic.

  1. Ellipse on the liver
  2. Histogram
  3. Statistics
  4. Length and Plot profile
Real app capture on an abdominal CT, Denoise off: an ellipse on the liver, its histogram and statistics, then a line profile across the kidney.
Try Professional free for 14 days

Professional is $45 a month or $449 a year per computer after the trial.

NEW IN 1.1.6

Your images, saved as PowerPoint slides.

Save as PowerPoint (.pptx)… saves the current image, or every image of the layout, as slides with the series, image number, window and measurements beside each picture. It is in the File menu, the toolbar’s Export menu and the image panel’s right-click menu, the same on Mac and Windows.

01 Save as slides Basic

Save the image or the layout as PowerPoint slides.

Choose Save as PowerPoint (.pptx)… and where to save. One image on screen makes one slide; with several panels, the first slide holds the whole layout as one picture, then each image has its own slide, the active panel first.

  • 16:9 slides on black: the picture on the left; on the right the series, the image number, the window and a table of that image’s measurements, the first 12, then “+N more”.
  • The speaker notes repeat the series, image and window lines, with the plane and the calibration where they are known.
  • The pictures are the ones Copy Image and Copy Layout make, with your Copy Options. The slide text and the file properties carry no patient name, ID, date or DICOM UID.

Included in every plan. During the trial or without a licence each picture carries the watermark strip below it, as a copied picture does. More in the manual

02 Plans

Both plans, with their prices.

Basic and Professional are shown with their prices when a five-minute session ends, in the trial reminders, in Help ▸ Licence… and when your trial ends, with one Subscribe button for the plan and period you choose.

  • Monthly or yearly, per computer: Basic US$10 a month or US$99 a year, Professional US$45 a month or US$449 a year.
  • The first launch after your trial ends says once what has changed and what each plan restores.

03 Deselect Basic

Click empty image to deselect.

A click on an empty part of the image deselects the measurement with every tool, so Copy Image (Ctrl+C, or ⌘C on a Mac) copies the image again instead of the measurement.

  • Esc deselects as before. With Window, Pan or Zoom, a drag still windows, pans or zooms and keeps the selection.

04 Movies & JPEG Basic

MP4 in H.264, and more JPEG files open.

MP4 movies, 3D rotation movies included, are encoded with the H.264 encoder built into macOS and Windows.

  • Where the system encoder cannot run, MP4 falls back to MPEG-4; WMV is unchanged.
  • JPEG Lossless, JPEG Extended and JPEG-LS images are decoded with a new library, which also opens JPEG Extended files that failed before.

Also in 1.1.6

  • Help ▸ Licence… shows when your trial ends, and says “Licence activated.” after a successful activation.
  • Help ▸ Licence… is also in the toolbar’s Help menu, and Help ▸ Open-Source Licences… lists the open-source software OmniDICOM includes.

Also new since 1.1.5: copies for PowerPoint slides, Excel/CSV results, numbered marks, Match and Open With, just below. Release notes →

Try the new tools free for 14 days

Already using OmniDICOM? Choose Update now when the app offers 1.1.6. Microsoft Store copies update through the Store.

NEW IN 1.1.5

From the viewer to your slides.

Copy one image or a whole labelled layout into PowerPoint slides, save Analyze results as Excel workbooks, number your arrows and measurements, match panels at the same physical scale and open .dcm files straight from Finder or File Explorer. The same on Mac and Windows.

01 Copy for slides Basic

Copy a labelled layout into PowerPoint slides.

Copy Layout (Shift+C) copies every visible panel as one high-resolution picture with panel labels, ready to paste into PowerPoint slides; Copy Image (Ctrl+C, or ⌘C on a Mac) copies the active panel.

  • Each panel is drawn again at a fixed size instead of being captured from the screen, so a copy looks the same on a Mac or Windows laptop and on a large monitor.
  • Copy Options sets the corner text, the panel labels’ style, position, size and colour, the lines between panels and the picture size (2400 or 3600 pixels on the long side), with a preview of exactly what Shift+C copies.
  • By default a copy carries image information but no patient identifiers, and a status-bar badge tells you when a copy would include them.
  • The image is copied as shown, with its measurements, arrows, typed text, rulers and orientation letters; the cursor readout, crosshair, cross-reference lines and series comments are left out.

Copying is included in every plan; trial and unlicensed copies carry a watermark on a strip added below the picture, never over the image. In the MPR window Shift+C copies all viewports as shown, crosshair included, and in the 3D window Ctrl+C (⌘C) copies the rendering. More in the manual

How to put DICOM images into PowerPoint slides (PPT)

Top: the app with coronary angiography, abdominal CT and DSA side by side, each showing its whole field of view. Shift+C copies the layout; paste with Ctrl+V, or ⌘V on a Mac. Below: the picture Copy Layout put on the clipboard, placed on a PowerPoint slide. A composite of an app capture and that slide; the keys and their labels are drawn in. Sample: LDCT-and-Projection-data, TCIA, CC BY 4.0 — credits

02 Excel and CSV Pro

Save Analyze results as Excel workbooks or CSV.

Analyze tables in Professional, including the ROI manager, statistics, histograms, profiles, particles and time-intensity curves, save as Excel workbooks (.xlsx) or CSV files that record each value’s series, image, slice location, pixel source and calibration.

  • Saved tables leave out the patient’s name, ID, birth and study dates, time of day and DICOM UIDs.
  • CSV files are saved as UTF-8 with a byte-order mark, so Excel shows non-Latin series descriptions and units such as mm² correctly.

More in the manual

03 Numbers Basic

Number your arrows and measurements.

Number Marks numbers your arrows and measurements 1, 2, 3 for each patient, so a slide or table can refer to “Mark 2”, and the numbers carry into copied and exported pictures.

  • Recolour an arrow from its right-click menu, or use Restyle All Arrows… to give every arrow, or every arrow of one colour, the same colour, thickness and head size.

More in the manual

04 Match Basic

Match panels at the same scale.

Right-click a panel and choose Match Other Panels to This One to show the others at the same physical scale and centre, so the rulers match and the panels stay in sync.

  • Series of the same scan, MPR included, line up by patient position; Also Match Window copies the window too.

More in the manual

05 Open With Basic

Open .dcm files from Finder or File Explorer.

Open .dcm and .dicom files straight from Finder or File Explorer with Open With ▸ OmniDICOM DICOM Viewer; your current default viewer stays the default unless you choose OmniDICOM.

  • To make it the default, use Get Info ▸ Open with ▸ Change All… on a Mac, or Open with ▸ Choose another app ▸ Always on Windows.

More in the manual

Also in 1.1.5

  • The toolbar’s Export button opens the Export images dialog in one click, and its arrow holds Copy Image, Copy Layout and Copy Options.
  • DSA, cine, measurements and supported exports follow the selected series.
  • 3D copies wait for the final-quality render, and duplicated views keep their calibration.
  • When more than one OmniDICOM window is open, a licence change in one reaches the others.

Also new since 1.1.2: De-identify, NIfTI export, text on images and series comments, just below. 1.1.5 release notes →

NEW IN 1.1.2

Four new tools for your research.

Make a de-identified copy, save a series as a NIfTI volume, type text on the image and leave a comment on a series. All four work in Basic, Professional and the 14-day trial.

01 De-identify Basic

De-identify a copy.

Select studies or series in the Local archive and choose De-identify. OmniDICOM saves a copy under the DICOM PS3.15 Basic Application Level Confidentiality Profile, with new UIDs, in a new folder. Your original files are not changed.

Text burned into the images is not removed. Only the DICOM header is changed: names, dates or ID numbers drawn into the pixels, or stored inside compressed image data such as JPEG comments, stay in the copy. Faces can be rebuilt in 3D from head CT and MR. Faces are not removed. Open the copy and check every image before you share it.

  • Dates: shift by a random number of days (intervals kept), remove, or keep
  • The patient’s name and ID are replaced by the new ID; other names and IDs, birth dates and private (vendor) tags are always removed
  • Kept only if you choose: age, sex, height and weight; the institution’s name and address; the scanner’s identity; study and series descriptions, after you review them
  • A summary of what was done, deidentification.txt, is saved with the copy; no link between the old and new identifiers is kept

Basic, Professional and the trial. Series marked as having text in the image, ultrasound, screen captures and photos are left out unless you include them; structured reports (SR), PDFs and other documents, and video are not copied. Whether the copy counts as de-identified under the rules that apply to you is for you to decide. More in the manual

  1. Select the study
  2. De-identify: new ID, dates shifted
  3. Copying 91 files
  4. Done: check the copy for text
Real app capture on a copy of a public CT study staged under a demo identity (DOE^JOHN, Example Hospital): De-identify with a new ID and shifted dates. The warning about text burned into the images stays in the window from start to finish. The copying wait is cut. On small screens the clip shows the De-identify window up close.

02 NIfTI Basic

Save a series as NIfTI.

File ▸ Export as NIfTI… writes each series as one .nii.gz volume in its original values (HU for CT), with its position and orientation in patient coordinates, for research tools that read NIfTI.

  • Also in the Export dialog, as NIfTI (volume)
  • Window, filters, rotation, crop and measurements are not applied
  • Optional: resample to even spacing (linear interpolation)
  • Professional: save the denoised values once Denoise has finished the series

Basic, Professional and the trial. Needs an original series of 3 or more parallel slices; viewer reconstructions, colour images and tilted-gantry series are not saved. More in the manual

  1. A CT series
  2. File ▸ Export as NIfTI…
  3. NIfTI (volume), original values
  4. Exported 1 NIfTI volume
Real app capture on a public abdominal CT, patient data hidden: File ▸ Export as NIfTI…, original values (HU for CT), Export. On small screens the clip shows the menu and the Export window up close.

03 Text Basic

Type text on the image.

  1. Text tool
  2. Click and type
  3. Larger, yellow
  4. Enter, then a second label
Real app capture on a public abdominal CT, patient data hidden: two labels typed with the Text tool.

Press T, click where the text should start and type. Pick a size and a colour, add a background box, or show the text on every image of the series.

  • Kept with the original series on this computer, not written into the DICOM files; on reconstructions such as MPR, for the session only
  • Shows in exported pictures and movies, also with Annotations set to Basic (anonymous): don’t type patient details on an image you will share
  • Send images takes it along as a DICOM presentation state; the text is not drawn into the images

2D images only. As with every picture export, pictures exported during the trial or without a licence carry the watermark. More in the manual

04 Comments Basic

Comment on a series.

  1. A series in the viewer
  2. Click the bubble
  3. Write a note
  4. Save: shown on the image
Real app capture on a public abdominal CT staged under a demo identity: a comment added from the thumbnail’s bubble.

Press N, or click the bubble on a series thumbnail, and write a note. A cine run can have its own.

  • Shows on the thumbnail, in the Local archive and, on larger panels, in a corner of the image
  • Kept on this computer only, not written into the DICOM files
  • Never exported: left out of exports, Copy, Send and de-identified copies

Up to 1,000 characters. Hidden while patient data is hidden. More in the manual

Also in 1.1.2

  • The trial reminds you as OmniDICOM starts: once with three days left and once with one day left.
  • Help ▸ Request a Feature… starts an email to us in your own mail app; Help ▸ Ask for a Longer Trial… appears in the trial’s last three days and after it.
  • Korean text in files labelled Latin-1 now shows as Korean.
  • Editing metadata: a value the file’s character set cannot store is refused with a warning, instead of being saved as question marks.
  • Professional: while Hold to compare shows the image without processing, the Filter line in its corner is hidden too.

THE TOOLKIT

See what you can do.

The same toolkit on both platforms. Basic covers the viewer; Pro adds advanced processing and analysis.

Windows warning: “Windows protected your PC” or “isn't commonly downloaded”?

Edge and SmartScreen warn about any new installer that few people have downloaded yet, even a signed one. The OmniDICOM installer is Authenticode-signed by its publisher, Youngrak Choi.

  1. Keep the download: in the Edge Downloads list, choose … › Keep › Show more › Keep anyway.
  2. Check the signature before you run it: right-click the .exe › Properties › Digital Signatures, select Youngrak Choi and choose Details. It must say “This digital signature is OK.” The name alone proves nothing: a modified copy still lists it.
  3. If “Windows protected your PC” appears, choose More info. Choose Run anyway only if the publisher is Youngrak Choi, not “Unknown publisher”.

Get OmniDICOM only from the buttons on omnidicom.com, which deliver the file from our official GitHub release, or from the Microsoft Store. Microsoft signs the apps its Store installs, so the Store copy shows none of these warnings. If there is no Digital Signatures tab, the signature is not OK, or it names another publisher, do not run the file. Step-by-step Windows installation →

QUESTIONS

Before you download

What happens after 14 days?

OmniDICOM keeps opening studies, in five-minute sessions. Exports carry a watermark and STL export needs a paid licence. De-identified copies and NIfTI volumes, which work during the trial, need a paid licence after it. Basic ($10 a month) lifts those limits for the whole viewer; Professional ($45 a month) adds Denoise, Process and Analyze.

Does Denoise upload images or change my files?

No. Denoise runs on your own computer and no image is uploaded. Your DICOM files are never changed: Denoise can be saved for the series on this computer, like other processing, and you can turn it off at any time.

Which scans and computers work?

The viewer opens CT, MR, angiography, ultrasound and other supported DICOM studies on Apple silicon Macs with macOS 13 or later and on 64-bit Windows 10 and 11. Denoise works on CT and MR series and on X-ray images (CR, DX, DR and RG), not on mammography; on a Mac it needs macOS 14 or later, and on Windows it uses the graphics card where available, otherwise the processor.

Can I use it for diagnosis?

No. OmniDICOM is for research and education only. It is not a medical device and is not intended for diagnosis, primary interpretation or clinical decision-making. This applies equally to denoised and processed images.

Which modalities does Denoise work on?

CT and MR series and X-ray images (CR, DX, DR and RG). For any other modality, mammography included, the Denoise button is greyed out and says so. Labelling workflows are planned; they are not part of the current plans.

Is the app in Korean?

The application interface and its built-in manual are in English. This site has Korean pages for the homepage and the how-to guides.

GUIDES

Learn the workflows.
