This is where the images (and the report) are displayed.
When a series contains multiple images, you can scroll through the images using the scroll wheel, the arrow keys or, after selecting scrolling in the menu, by holding the left mouse button and moving the mouse up and down.

In case you have activated the setting "Right click for function switch" in 4.4 User settings > 4.4.1 My account, you can switch between the following functionalities with short clicks on the right mouse button:

  • Window Level
  • Scrolling
  • Stepless zoom
  • Pan

If you hold down the right mouse button for 1 second or longer, the extended context menu will be displayed.

Image editing tools:

Using the image editing tools (see 5.3 Werkbalk) you can zoom in on/zoom out of the image, rotate the image, perform measurements, change contrast, etc.

You can also right-click the mouse for a menu with the most-often used commands:

  • : Display the DICOM tags of the selected image

  • : Display the original DICOM tags of the selected image (only available to administrators of the study)
  • : Print the selected image
  • : Download the selected image in PNG format

You can view an image in full-screen mode by double-clicking on the image. Double-clicking the image again will take it back to its original size.

Within the study page, the following short cuts can be used:

CTRL + left mouse button clicked + dragging image to another view port: duplication of image in second view port

SHIFT + left mouse button clicked + dragging image to another view port: switching images between view ports

SHIFT + scroll forward: zoom in

SHIFT + scroll backward: zoom out

CTRL + scroll: tiling within the selected view port

Left mouse button clicked + scroll: fast select between the following functionalities:

    • Window Level
    • Stepless Zoom
    • Pan

ONLY for series containing multiple images:

Hold down the mouse wheel + move the mouse up and down: scroll through the series.

Attention: the speed for scrolling is adaptive. Depending on the velocity used when moving the mouse back and forth, the scrolling will be faster or slower (non linear).
The same remark holds when scrolling through a series on a mobile device (tablet or smartphone)


In case an anomaly was registered for an exam with respect to the exam on the local PACS system a notification is displayed on top of the page.
When hoovering over the notification, a label with a more detailed explanation on the anomaly is displayed.
If you are logged on as a user with administrative rights on the study, it is possible to click the label to navigate directly to the section "Anomalies" of the administration page (X Anomalies). 

Image retention:

When placing the cursor over the clock icon, a pop-up is shown, displaying the retention time for the different series.

Linking series:

In case two viewports display image series with the same table position, the series are linked automatically.
In case two series are linked, it can be seen as the shackle icons of both series on the bottom left and scrolling through both series occurs simultaneously.
You can unlink the series by clicking the shackle icons to scroll through the series separately.

Automatic or manual linking of series is not possible in case one of the series is an MPR.

Key image:

Administrators of a study on PACSonWEB have the possibility to create a new series with ‘key images’.
You can add an image to this series, by make it visible in the viewer and clicking the star icon in the bottom right corner of the image which will make it turn yellow.

When reloading or reopening the study, the newly created series on key images will be available in the series picker for everyone who has access to the study.

You can remove images that have been marked as key images from the series by de-selecting the star icon. Images on which publicly available annotations have been made, are automatically marked as key image.

You can open an image from the key image series in the original series by clicking  at the bottom of the image.
