Launch Weasis

Demo: Multiple DICOM Samples

This page collects a curated set of DICOM samples designed to exercise the rendering pipeline, the input formats, and the headline features of the Weasis DICOM viewer. Each sample loads in one click and is annotated with the test it is meant to demonstrate, along with the expected viewer behavior.

The datasets are sourced mainly from the DICOM standard repository and the publication DICOM Image Display Consistency: A Test Environment.

Tip

Sample naming conventions

  • Patient Name — begins with TEST^, followed by the general test purpose. A TEST-i18n- prefix indicates an internationalization test.
  • Study Description — describes the overall test focus.
  • Series Description — details the specific test purpose of that series.

How to launch Weasis

To view a DICOM sample, make sure you have installed the latest version of Weasis.

Tip

Clicking a Launch button opens Weasis and displays the sample. If Weasis is already running, the dataset loads in a new tab.

DICOM testing categories and samples

The samples below exercise specific parts of the DICOM standard and the Weasis rendering pipeline. Click Launch to load a dataset.

Internationalized Characters

Test international character sets in patient and study identifiers.

Launch
Info

Expected output: charset samples charset samples

Pixel Depth (9-bit to 16-bit)

Verify that images render identically regardless of the underlying pixel depth (signed or unsigned, 9 to 16 bits per sample).

Info

Expected output: images render identically regardless of the pixel depth.

Compression Tests

Exercise the decoder against the main DICOM transfer syntaxes and fragmentation scenarios.

  • Different compression syntaxes (JPEG, JPEG-Lossless, JPEG-LS, J2K, RLE) Launch
  • Compression with fragments (the encoded pixel-data stream is split into several fragments, see DICOM Part 5) Launch
  • Compression + multi-frame + fragments combined Launch

Photometric Interpretation

Test multiple photometric interpretations (color models, monochrome, and palette color).

Launch

Pixel Spacing

Test the pixel spacing on different modalities by measuring the distance between known landmarks. See also Spatial Calibration.

Launch
Info

Select the view and press D (default — see Keyboard Shortcuts to customize) to draw a line and measure the distance. Follow the on-image procedure that lists the acceptable pixel-spacing range.

Pixel Padding Value

Test the pixel padding value and its effect on the image.

Launch
Info

Toggle padding from the Display right-side panel. When padding is enabled, the marked pixel values are excluded from rendering.

Non-Square Pixels

Test images with non-square pixels to verify correct stretching.

Launch
Info

The viewer should stretch or shrink the image according to the Pixel Spacing or Pixel Aspect Ratio tag.

Overlay

Test the rendering of DICOM overlays on top of the image.

Launch
Info

Show or hide overlays from the Display right-side panel.

Modality LUT

Test the Modality LUT and its effect on image rendering. See also Lookup Tables (LUT).

Launch
Info

Expected output: every variant should render the same image.

VOI LUT

Test the VOI LUT and its effect on image rendering. See also Lookup Tables (LUT).

Launch
Info

VOI LUT settings can be adjusted in the Image Tools right-side panel.

Combined LUT

Test the combined effect of Modality LUT, VOI LUT, and Presentation LUT on image rendering. See Lookup Tables (LUT).

Launch
Info

Expected output: identical rendering regardless of which LUT combination is applied.

DICOM Shutter

Test DICOM shutters and their effect on image rendering.

Launch
Info

Show or hide shutters from the Display right-side panel.

DICOM PDF

Test the handling of DICOM-encapsulated PDF files.

Launch
Info

Opens with the default PDF viewer of the operating system.

DICOM Video

Test the rendering of DICOM video files with different transfer syntaxes.

Launch
Info

Opens with the default viewer associated with the video MIME type. On Windows, this is Windows Media Player, which does not ship with an MPEG-2 codec by default — install VLC or another video player if playback fails.

DICOM Audio (AU)

Test the handling of DICOM audio files. See also DICOM Audio Player.

Launch
Info

Plays audio with the embedded Java Audio Player.

DICOM Floating-Point Pixel Data

Test DICOM pixel data carrying float or double values (used by parametric maps, AI probability maps, perfusion / diffusion maps).

Launch
Info

Expected output: the float / double pixel values are supported by the Window / Level tools.

DICOM Structured Report (SR)

Test the rendering of DICOM Structured Reports. See also DICOM SR Viewer.

Launch
Info

Structured reports are formatted hierarchically following the SR tag order. Links to images and associated graphics are clickable.

DICOM Presentation State (PR, GSPS)

Test the rendering of various DICOM Presentation States.

Info

Click the icon at the top-right of the image to select a Presentation State to apply. See How to build DICOM PR.

    Note

    This sample is produced by a GE workstation and contains some proprietary items, so not every PR can be applied.

DICOM Key Object Selection (KO)

Test the rendering of DICOM Key Object Selections.

Launch
Info

Click the icon at the right of the image to select a Key Object Selection. See How to build and export DICOM KO.
