Can I load multiple datasets simultaneously in Vesalius3D?

Yes you can. Select multiple datasets in the Library and choose the “open” functionality (CRTL+O) or use the “add”, “add recent” or “add from Library” functionality.

Can I load directly into Vesalius3D or do I need to use the Library?

Yes, data can be loaded directly into Vesalius3D. Browse to the folder storing the data, select the desired data file, and click “Open”. Note that this dialog only supports data formats that store a volumetric dataset in a single data file. When a set consisting of multiple separate images should be opened, the data first has to be imported using the Vesalius3D Data Library.


How can I easily fly through the data in Vesalius3D?

The “near plane” is a special plane for the 3D window. It allows users to traverse (fly through) the dataset. It is a cropping plane between the user and the 3D dataset. The plane is fixed and the user can drag the data through the plane creating a first world perspective. “Window – Add Near Plane” or clicking the “right mouse button” in the 3D view and selecting the “Add Near Plane” functionality.

How do I orientate a dataset using the mouse and keyboard in Vesalius3D?

What is the difference between a orthogonal and an oblique cropping plane?

Ortogonal planes move along the 3 axis of the data. The planes that share an axis have similar colors. The left and right cropping planes are red, the anterior-posterior planes green and the inferior superior planes are blue.

Oblique planes can be positioned and oriented freely in the 3D view. Oblique planes are shown in a brown-ochre color. When additional oblique planes are added, these planes get a different color.

How is the near plane different from an oblique plane?

The near plane is a cropping plane between the user and the 3D dataset. The plane is fixed and the user can drag the data through the plane creating a first world perspective. (Fly through experience). There is only one near plane.

An oblique plane is not fixed and can be oriented freely though the data and the 3D space.  There can be multiple oblique planes.


What happened to the high resolution visualization functionality?

Starting Vesalius3D 2.7.0 high resolution visualization is always on. Our tech wizzards were able to improve the visualization without using additional processing power.

Users always have the high resolution visualization and the on/of feature is no longer needed.

Can I optimize Vesalius3D for performance and for visualization?

Vesalius3D has several options to optimize your PC for Vesalius3D. See the tutorial video – Optimizing for your PC.

  • The Quality Slider is used when we’re able to open the dataset but interaction is slow using this dataset.
  • The setting Maximum Dataset Dimensions is used when the 3D view does not appear and/or your PC consistently runs slow (PC memory issue).
  • The setting Data Import Resolution can be used to render 16 Bit datasets at 8 Bit.

The “Quality” slider (next to each visualization in the datasets panel) allows the user to alter the ratio between the quality of the volume rendering versus the speed of the rendering. The higher the quality is set (slider to the right), the more the rendering speed is impacted. This depends on the quality of the system on which Vesalius3D was installed.

A third optimization is a result of selecting the “render resolution”. This setting allows you to toggle between 8-bit and 16-bit resolution. Enabling 16-bit resolution does impact rendering performance, and degradation in interaction speed may be noticeable. Activating 16 bit rendering is done in the settings menu (“File – Settings – 3D rendering”). The effect is less then choosing the Maximum Dataset Dimensions).

Unexpected results

Vesalius3D crashed what should I do?

It is very unfortunate that Vesalius3D crashed and it should of course not happen. Please try again and see if the problem reoccurs. If this is the case, please contact with a description of your workflow before the crash and we will help you the best we can.

After loading a dataset, my 3D-View remains black and I do not see my data. My 2D-Views however do show the data. What is happening?

This means that the graphical computing power on your computer is not sufficient.

Scale back the Maximum Dataset Dimensions. This limits the memory usage of Vesalius3D. For instance a limit of 512 compared to 1024 reduces the maximum datasize 8 times (2x2x2 as it is a volume). Any dataset that is within the limits is not scaled. Changing the Maximum Dataset Dimensions is done in the settings menu (“File – Settings – 3D rendering”).

If this does not resolve the issue, Vesalius3D can not run with your graphics card. In order to use Vesalius3D please upgrade your graphics card.


Is there a limit to the Vesalius3D Library?

It is limited to the size of the hardware you installed the Library on.

I uploaded new data into the Library, where is it?

The Vesalius3D Library has many search functionalities to locate your data. An easy way is to type the patient name or the current data into the search field.

Where is the Library on my computer?

Under “File – Settings – Application” , the database location is shown.


When I save my work in Vesalius3D how can I find it?

States can be found in the Library and after opening a dataset (combination of datasets)

From an open dataset  states can be found under “Presets – Open Presets – Presentation States”. Thumbnail(s) of the state(s) of the dataset or combination of datasets are now shown.

In the “Library” datasets with a state or mulitple states have a checkmark in the column State. Thumbnail(s) of the state(s) will be shown in the Presentation States window when the corresponding dataset is selected.

I seem to be missing some presentation states. Where did they go?

Vesalius3D displays presentation states of datasets in the Library. If you feel that all associated datasets are in the Library, then press the “Reload States” button in the “Application Settings” tab of the “Settings” menu.

What is the difference between a state and a protocol?

Protocols are not related to datasets. They apply to all data that matches the set of rules in the protocol. States are related to only a specific dataset or combination of datasets.

Where are the protocols?

Starting Vesalius3D 2.7.0 starting visualizations are used in stead of protocols to open a dataset. This was done to streamline the workprocess. However Protocols are still available and can be found after opening a dataset under “Presets – Open Preset – Protocol”

System requirements

What hardware do you recommend for Vesalius3D?

For optimal performance we recommend these (or higher) system specifications:

Operating SystemWindows 10
Video CardNVIDIA GTX 950 or AMD R7 370
ProcessorIntel Core i5

Can I use Vesalius3D on systems not meeting the hardware recommendation?

Vesalius3D will work on many Windows-based PC’s and laptops (Windows 7 and 10). Depending the size of the data more resources of your computer are allocated. The most important feature is your Graphical Processing. The better the Graphical card the better the performance. A gaming laptop or a pc with a decent video card will normally be sufficient.

Furthermore Vesalius3D has settings to optimize Vesalius3D for a users computer.
See the tutorial video – Optimizing for your PC.

Can I use Vesalius3D on MAC OS or Linux?

Sadly, this is not yet possible. Vesalius3D is optimized to work with Windows and no MAC OS or Linux support has been implemented yet.
