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.
