Function: thresholdVolumeByRange()

thresholdVolumeByRange(segmentationVolume, thresholdVolumeInformation, options): Types.IImageVolume

It thresholds a segmentation volume based on a set of threshold values with respect to a list of volumes and respective threshold ranges.

Parameters

• segmentationVolume: ImageVolume

the segmentation volume to be modified

• thresholdVolumeInformation: ThresholdInformation[]

array of objects containing volume data and a range (lower and upper values) to threshold

• options: ThresholdRangeOptions

the options for thresholding As there is a chance the volumes might have different dimensions and spacing, could be the case of no 1 to 1 mapping. So we need to work with the idea of voxel overlaps (1 to many mappings). We consider all intersections valid, to avoid the complexity to calculate a minimum voxel intersection percentage. This function, given a voxel center and spacing, calculates the overlap of the voxel with another volume and range check the voxels in the overlap. Three situations can occur: all voxels pass the range check, some voxels pass or none voxels pass. The overlapType parameter indicates if the user requires all voxels pass (overlapType = 1) or any voxel pass (overlapType = 0)

Returns

Types.IImageVolume

segmented volume
