How To Use Medical Imaging XR Panel
-
Introduction
- Load your DICOM dataset from the Library.
- The Medical Imaging XR Panel will automatically appear.
-
Color Section
- Located at the top of the Panel.
- Adjust transparency levels ranging from 0% to 100%.
- Assign colors to specific Hounsfield Units (HU) using Color Pins. Modify these values by moving the Color Pins vertically for transparency and horizontally for HU values.
- Utilize the Color and Hue Pickers on the right side to alter the color of each pin.
-
Preset Section
- Found on the left side of the Panel.
- Medicalholodeck offers various built-in color presets.
- Customize a preset by adjusting or adding color pins.
- Save your settings by clicking the '+' Button, creating a new custom preset.
-
Tissue Filter Section
- Includes the Lower and Upper Hounsfield Unit (HU) Buttons to window DICOM data and visualize specific body tissues.
-
Toggle Between Relative and Absolute Color Values:
- Absolute Mode: Colors are strictly tied to specific Hounsfield Units (HU). Each color corresponds to a defined HU value, ensuring consistent visualization across different datasets. Adjusting the HU range will display only the colors associated with the selected HU values.
- Relative Mode: Colors adapt dynamically based on the current HU window. The entire color spectrum adjusts and remains visible within the selected HU range, emphasizing variations without being constrained by fixed color assignments.
-
Mesh Generator Section
- Generate a 3D mesh from DICOM data for 3D printing or further analysis.
-
Edge Filter Section
- Enhance visibility of transitions between different tissue densities.
- Adjust the filter to focus on homogeneous tissue or highlight rapid changes in tissue density:
- Homogeneous Tissue Focus: By sliding the filter to the left, users can emphasize regions of uniform tissue.
- Rapid Density Change Highlight: Shifting the filter to the right will spotlight areas showcasing swift transitions in tissue density, such as the interfaces between muscle and bone.
-
Quality Section
- Fine-tune the balance between visual quality and application performance.
- Optimize data display based on your computer's capabilities.

How To Make a Screenshot
To capture an image of your experience use the Screenshot Button located in the Main Control Pad. Point your laser at the button and click the trigger to take a screenshot, the image will be automatically saved to your Desktop.Note: Before capturing a screenshot, ensure that you have sufficient free space on your hard drive. Insufficient storage may prevent the image from being saved successfully. Regularly check and manage your storage to avoid any disruptions.
How To Create a Video
To record a video of your experience, use the 'Record' Button located in the Main Control Pad. Point your laser at the button and click the trigger to start recording. To stop recording, click the same button again. The recorded video will be automatically saved to your Desktop.Note: Before starting a video recording, ensure that you have sufficient free space on your hard drive. Videos can occupy a significant amount of storage, and insufficient space may prevent the video from being saved successfully. Regularly check and manage your storage to avoid any disruptions.
How To Create and Use Saved Scene
Saved Scenes allows you to save and store scenes for future use, providing a convenient way to arrange your data. You can load multiple datasets from each Medicalholodeck application: Medical Imaging XR, Dissection Master XR, and Anatomy Master XR. This allows you to combine and compare different datasets within the same scene. Once your datasets are loaded, you can manipulate them in various ways. You can cut DICOM datasets, draw on them, place markers, and adjust their size. When your scene is prepared, save it for future use by clicking on the 'Save Scene' Button on the right side of the Library Panel. A thumbnail with a scene number will appear, indicating that your scene has been saved successfully. The next time you open Medicalholodeck, you can load your saved scene by clicking its thumbnail in the Library Panel. All the datasets, objects, and modifications you’ve prepared will be loaded, allowing you to resume your work or start giving a lecture immediately.How To Create STL File From the DICOM Dataset
- Load your desired DICOM dataset from the Library Panel into the environment.
- Once loaded, the Medical Imaging XR Panel will appear.
- Adjust the window levels using the Lower and Upper Hounsfield Unit (HU) Buttons to make the desired body tissue visible.
- Navigate to the Mesh Generator Section below the Tissue Filter Section.
- Click 'Generate Mesh'. A mesh dataset will appear alongside the original dataset, and additional options will be displayed.
- Use the ISO value Button on the tissue slider to set the Hounsfield Unit (HU) value from which the mesh is generated, adjusting the visibility of specific tissues.
- Opt for the 'Smooth' Button if you wish to refine the mesh's appearance.
- Balance detail and file size with the 'Mesh Quality' slider:
- Move left for fewer vertices, resulting in a smaller, less detailed file.
- Move right for more vertices, yielding a larger, more detailed file. The predicted file size is displayed for reference.
- Once content with the mesh preview, click 'Export STL' to save the 3D mesh as an STL file on your desktop.
- Click 'DONE' to add the generated mesh to the Library.
