Threshold Segmentation Options
Threshold is a contouring tool that allows you to segment objects based on a fixed range of intensity values.
The tool can be used on MR, CT, PET images and images generated with Brainlab Elements Contrast Clearance Analysis to extract contrast enhanced structures, such as:
Burned-in objects (e.g., BOLD fMRI, TMS)
ROI for Threshold to be applied. Can be set to:
Sphere: Uses all voxels inside a user-defined sphere.
Full Volume: Uses the complete image set.
Any segmented object that is available.
Threshold intensity slider: Adjust the intensity range to be used for segmentation.
Can be used to set the number of independent components or voxel islands that the segmentation results in.
Set to 1 to use only the biggest voxel island.
Set to All to use all voxel islands.
Select Apply to segment the object based on the values in the controls.
