Launch Weasis

Demo with multiple DICOM Samples

This page shows a list of DICOM samples for testing viewer capabilities.

Naming convention

  • Patient name starting with “TEST^” and then the general test purpose. “TEST-i18n-” prefix is for internationalization test.
  • In study description: general test description
  • In series description: test description

The demo server is on a free cloud system, so sometimes it requires to launch two times the viewer because the server has to wake up (is turned “idle” after a period of inactivity).

How to launch Weasis

To display the DICOM samples on this page, you need to install a recent version Weasis.

The version 3.5 and superior uses the weasis protocol instead of Java Web Start because which has been removed from Java 11 release.


Internationalized characters

Should display: charset samples


Pixel depth (from 9-bit to 16-bit)

Should always render the same image.

  • Unsigned data

  • Signed data


Compression

  • Different compression syntaxes (JPEG, JPEG-Lossless, JPEG-LS, J2K, RLE)

  • Compression and fragments (the file contains the encoded pixel data stream fragmented into several parts, see DICOM part5)

  • Compression, multi-frame and fragments


Photometric Interpretation


Pixel Spacing

Select the view and press ’d’ to draw a line.


Pixel Padding Value

Show or hide pixel padding from the “Display” right pane.


Non-square pixels

Stretch or shrink the image according to the “pixel spacing” or “pixel aspect ratio” field.


Overlay

Show or hide from the “Display” right panel.


Modality LUT

Should always render the same image.


VOI LUT

Can be changed in the “Image Tool” right panel.


Shutter

Show or hide from the “Display” right panel.


DICOM PDF

Open by the default PDF viewer of the operating system.


DICOM video

Open by the default viewer (associated to the video mime type) of the operating system.


DICOM Audio (AU)

Open by the embedded Java Audio Player.


DICOM floating point pixel data


DICOM Structured Report (SR)


DICOM Presentation State (PR, GSPS)

Click on the right icon over the image to select the Presentation State. Show or hide graphics layers from the “Display” right panel. See How to build DICOM PR.

  • Shutter Test

  • Text Annotation

  • Displayed Area

  • Modality LUT PState

  • VOI LUT PState

  • Presentation LUT PState

  • Combined LUT PState

  • Spatial Transformation

  • Overlay

  • Graphics Annotation

  • Complex Combination

  • GE RA600 Test of CPI GSPS

This sample is produced by a GE workstation and contains some proprietary items (so not all PRs can be applied)


DICOM Key Object Selection (KO)

Click on the right icon over the image to select the Key Object Selection. See How to build and export DICOM KO.
