To import files, press the "Import Data" button in the Medical Imaging section in the Library. Choose the Cloud tab and find the 6-digit access code on the right side of the window, you’ll need it to connect your VR headset to Medicalholodeck Link.
Visit medicalholodeck.com/link in your browser and enter the 6-digit access code in the window that appears. It will close and your headset will be listed as online.
Select 'Upload' from the menu. An upload box will appear, ready to receive your files. Medicalholodeck supports various file formats, including DICOM, STL, OBJ, PDF, JPG, and MP4. Drag and drop your files into the upload box or click choose directory and use file explorer to find desired data. Then wait for the upload to complete.
Put on your VR headset again. Select the files you want to import and click the 'Import datasets' button at the bottom of the screen. They will now be available in the Medical Imaging section, ready for use.

To import files, press the "Import Data" button in the Medical Imaging section in the Library. Stay in the local disk tab and use the file explorer to navigate to your data. Medicalholodeck supports multiple file formats, including DICOM, STL, OBJ, PDF, JPG, and MP4 files. Select a single file or an entire folder, then click the “Select” button at the bottom.
Medicalholodeck will analyze the contents and display all compatible files for review. Select all the files you want to import and click the 'Import' button at the bottom of the screen. Your data will be added to the Library and will be ready for use.
To display a DICOM dataset from the library, press its icon with the trigger. The data will load in front of you. You can display multiple DICOM datasets side by side, and load the same one multiple times for detailed comparison. Each dataset has an object marker on the floor - blue for active, gray for inactive datasets. Only the active dataset can be edited. To activate another dataset, grab it with your hands or select it using the laser.

You can edit any DICOM data using functions from the Medical Imaging panel, which appears when a DICOM dataset is loaded.
The Transfer Function at the top allows you to adjust transparency and assign colors to specific Hounsfield Units, using color Pins. Hounsfield Units, or HU, allow you to filter DICOM data based on radiodensity.
To add a new pin, click anywhere within the section. Move the pins vertically – to adjust transparency, or horizontally to assign colors to specific HU values. Click at a pin to open the additional panel on the right, where you can change the pin's color or remove it.
In the Tissue Filter section, use the arrow buttons or drag the pins along the slider to set the visible HU range. In the Relative mode, colors are mapped relative to the currently selected HU window. When you adjust the HU range, the entire color spectrum is redistributed across the new range. In the Absolute mode colors are fixed to specific Hounsfield Units. Narrowing the HU range limits the visibility of the colors associated with values outside that range.
To save the transfer function, press the 'Add' button below. Switch between the saved functions by clicking on their icons. You can also export them to your desktop or delete them.
Use AI Segmentation to detect specific parts in a dataset. Choose a suitable model from the list and press 'Start'. Once the process is complete, the visibility and transfer function of each detected part can be edited separately using the Segmentation panel.
To convert the dataset into an STL format, press the 'Generate mesh' button. Use the Tissue slider to set the ISO Value that controls which tissues appear in the mesh. The Mesh Quality balances mesh detail and STL file size. Press the 'Smooth' button to smooth out the created mesh. Click 'Export STL' to save the file to your desktop. Press 'Done' to add the mesh to the library.
Toggle the visibility of the Multiplanar and display the DICOM data in axial, sagittal and coronal planes. Use the sliders to choose specific planes to display and interact with the 'Zoom in' and 'Zoom out' icons to adjust their scales. Modify the window for adjusting the range of grayscale values displayed and threshold for changing the displayed HU range.
The Edge Filter improves the clarity of tissue boundaries in the DICOM data. Use the arrow icons or drag the pins along the slider to adjust the filter. Move it to the left to display smooth areas or to the right to highlight tissue transitions.
Transfer function, AI segmentation and edge filter settings can be saved as option presets by selecting the 'Add' option located on the left side of the panel. To load a different preset, click its section. You can also rename presets, save them to your desktop or remove them.
The slider in the Quality section controls how many slices are used for rendering, balancing performance and visual quality.
The data resolution controls how sharp each slice appears and can be set to Low, Medium or Full.

Use functions from the Object Pad to interact with DICOM data.
Masking is used to selectively control the visibility of specific regions within a dataset. When the tool is activated, a red ball appears at your controller's fingertip, allowing you to 'paint' in 3D space. Pressing the mask button opens an additional panel.
Use the slider to adjust the diameter of the red ball.
Switch between three masking modes. Isolate keeps only the selected area visible, Hide makes it invisible, and Highlight visually emphasizes selected areas.
To remove masking, select the Eraser tool. Point at the affected area and hold the trigger.
Mask Channels allow you to control multiple masked areas within your dataset. Switch channels to apply and manage independent masking effects.
At the bottom of the panel, the volume of the currently masked area is displayed.
To measure surface area, select the Area Measuring tool from the Object Pad. A black cone will appear at the controller's fingertip. While in the Area Connecting mode, use the additional panel to switch between area types.
In the Circular mode use the trigger to place the center point. Each new point will connect to both the center and the previously placed point, forming a shape around the center. Select one of the points to close the shape. The surface area will be displayed in square millimeters. The new shape can be adjusted. Aim at a point and hold the trigger to reposition it.
In the Continuous mode, there is no fixed anchor point. Each new point connects to the two most recently placed points.
To measure cylindrical shapes, switch to the Cylinder Connecting mode. First set the diameter of the base, then the height of the figure.
To measure linear distance, select the Distance Measuring tool. Set the start and end points with the trigger.
Select the Delete tool to remove objects such as measurements, shapes, or drawings from the workspace. A red X will appear at the controller's tip. Aim at the object and press the trigger to delete it.
To measure an angle in 3D space, start by selecting the angle measuring tool from the pad. Then press the trigger to set the vertex and place the two arms of the angle by setting each endpoint. The angle will appear in degrees as soon as both lines are placed.
To place a visual marker, select the Marker tool. A colored arrow will appear at your controller's fingertip. Move it into place and press the trigger to drop the marker.
