Module Description

This module can be used in order to compute bone morphometry features of an input image. The computation of the bone morphometry features is based on a binary segmentation of the whole image and it based on the itk remote module: itkBoneMorphometry itkBoneMorphometry.
The following Bone Morphompetry Features are computed:

• percent bone volume [BVTV]
• trabecular thickness [TbTh]
• trabecular separation [TbSp]
• trabecular number [TbN]
• Bone Surface to Bone Volume ratio [BSBV]

Use Cases

Inputs: Input volume [index: 0] : Input Volume Input mask [-s --inputMask] (None) : A mask defining the region over which texture features will be calculated Inside Mask Value [-i --inputMask] (1) : The pixel value that defines the ”inside” of the mask Threshold [-i --inputMask] (0) : The threshold value that will be used for the binary segmentation of the image Neighborhood radius [-n --neighborhoodRadius] (4) : The size of the neighborhood radius Outputs: BVTV [output] : percent bone volume feature value TbTh [output] : trabecular thickness feature value TbSp [output] : trabecular separation feature value TbN [output] :trabecular number feature value BSBV [output] : Bone Surface to Bone Volume ratio feature value Advanced: Output Vector [output] : Output vector containing all the feature value stored in the same order than previously
