Method and apparatus of segmenting an object in a data set and of determination of the volume of segmented object

摘要

The invention relates to a method of segmenting an object in a data set, wherein the object is initially segmented resulting in a first set (N0) of voxels. An erosion operation is performed on the first set (N0) of voxels resulting in an eroded set (N−) of voxels. A dilation operation is performed on the eroded set (N−) of voxels resulting in a dilated set (N+) of voxels. The erosion operation depends on a variable erosion threshold (Θ−), and the dilation operation depends on a variable dilation threshold (Θ+).
