Performance Issues

Understanding DICOM Data and Performance

DICOM datasets are essentially point clouds. The closer you zoom in or the larger you scale the dataset, the system needs to interpolate and display more points, exponentially increasing the performance demand. Every system has its limits based on how data is handled, scaled, and visualized.

Best Practices for Optimizing Performance

Limit the Number of DICOM Datasets Loaded in the Viewport:
  • Avoid loading too many datasets simultaneously into the active viewport. Datasets loaded but not actively displayed are fine and won’t impact performance significantly.

  • Avoid Excessive Scaling:
  • The original scanner resolution is typically 512x512 pixels per slice. Beyond this resolution, the data is interpolated, which adds no real value for surgeons but significantly increases computational load.

  • Avoid Zooming in Too Closely:
  • For example, scaling a heart to 4x4 meters and zooming in too much causes excessive interpolation and computational demands. This will challenge any system and may lead to crashes.

  • Adjust Quality Levels:
  • Experiment with quality settings:
  • Low, Medium, High: Try different levels based on your needs and system performance.
  • Quality Scale (0%–100%): In most cases, increasing the quality beyond 50% doesn’t yield significant visual improvement. Adjust this setting to balance performance and visualization.

  • Set Generic Quality Levels in Medicalholodeck Settings:
  • Predefine the quality level for all loaded DICOM datasets to optimize performance from the start.
  • By following these guidelines, you can achieve a smoother workflow while maximizing the utility of your advanced setup.

    Features and Functionality

    Medical Imaging XR is the DICOM viewer in virtual reality. Visualize, edit, and discuss medical imaging in collaborative teams in VR. The application is used around the globe for postoperative case reviews, surgical teaching, training, and medical education.
    Dissection Master XR is the leading human anatomy atlas and dissection lab in virtual reality. Based on dissections of real human bodies, the software visualizes the anatomy of the human body in a superb level of detail in a fully immersive holographic space. Dissection Master XR is used around the globe for anatomy and medical teaching.
    Anatomy Master XR is the three-dimensional human anatomy atlas in virtual reality. It brings Zygote's highly detailed male and female 3D anatomy models to VR. The app is used worldwide to teach basic anatomy in universities, medical and nurse schools, and K12 education.
    RecordXR is the recorder for the Metaverse. Record your content, create lessons, store, and share them with users and your students worldwide. All in virtual reality.
