4D CT Heart Tool for Left Heart Chamber Segmentation: Quantitative Validation

Discover how automation enables you to increase accuracy and efficiency.

The accurate segmentation of heart chambers is crucial to characterize cardiac defects, obtain detailed anatomical information, plan therapeutic procedures, and design or validate medical devices. Manual segmentation of 4D CT images is, however, a time-consuming, tedious, and error-prone task due to poorly visualized valves and the often weak image contrast with neighboring tissues. Automation is therefore highly desirable.

What you will learn

  • How to achieve high-quality semi-automatic segmentations of the left heart chamber and its corresponding vessels
  • How to reduce the time required for a full cardiac segmentation by factor 4 (compared to the separate application of the CT Heart Tool in each phase)
  • How to automatically propagate the segmentation process to other phases of the cardiac cycle
  • How the increase efficiency while significantly reducing the need for manual editing
