ABSTRACT

Objective:

To investigate the potential of gradient vector flow(GVF) Snake model as a method of image segment in radiographic absorptiometry method (RA) which is used to qualify bone mineral density.

Methods:

The Gradient Vector Flow model and the Region Growing method were applied in the segmentation of the middle phalanges image and aluminum wedge image separately in this paper. Then, the results can be compared.

Results:

The experiments shows that GVF Snake model is not only robust and practicable, but also segmentation results are in line with the actual border.

Conclusions:

GVF Snake model is very useful, and can be widely used in qualifying bone mineral density.
