Module Description
This module performs the segmentation of the left atrium from MR images. It is an implementation of a region-growing-based method with a shape prior. The module starts from a manually generated seed region inside the left atrium. Then, the growing process gradually captures the whole left atrium region.
Use Cases
This module is specifically designed for the segmentation of the left atrium from MR images.
Tutorials
- Load source image
- Select Editor module
- Choose Master Volume and Merge Volume (label map to be used for the left atrium seed region)
- Select PaintEffect and adjust Radius (in mm) so that the painted seed region (a circle) is completely inside the left atrium
- Go to the Axial view, choose a slice that is approximately to the center of the left atrium. Then, draw a circle that lies to the center of the left atrium on the slice
- Go to Segmentation->Left Atrium Segmentation module
- Select Original Image, Seed Label Image (the one obtained from the Editor module), and select/create Segmentation Results
- Adjust parameters if needed
- Press Apply button and it takes several minutes to process one volume
