Automatic segmentation technique for acetabulum and femoral head in CT images

作者:

Highlights:

• Classify the hip joints into four groups based on anatomical and imaging criteria.

• Divide the image set into bone and non-bone classes for the initial segmentation.

• Present a Bayes decision rule for segmenting the femoral head and acetabulum.

• Refine the bone boundaries based on normal direction of vertices of bone surface.

• Evaluate our method based on clinical application criteria (good, moderate and poor).
