02 / THE CHALLENGE
Cardiac anatomy is complex to isolate across volumetric imaging data.
Cardiac CT data contains complex anatomical boundaries across hundreds of image slices, making consistent segmentation a challenging and time-intensive task.
Manual delineation requires structures to be identified across multiple views while maintaining anatomical consistency throughout the volume. This becomes particularly demanding when the segmented data must later support accurate three-dimensional reconstruction and structural analysis.
The challenge was to develop an automated approach capable of identifying cardiac structures across volumetric imaging data and producing segmentation outputs suitable for detailed 3D visualization.
NeuralFlex developed a deep-learning segmentation pipeline that processes volumetric cardiac imaging and identifies anatomical regions across individual scan slices.
The predicted segmentation masks are combined across the imaging volume to reconstruct the segmented cardiac structures in three dimensions. This creates a continuous representation of the anatomy that can be inspected from different perspectives and used for further structural analysis.
The workflow connects medical image processing, automated segmentation, and 3D reconstruction within a unified cardiac imaging pipeline.
