This paper proposes an extraction method of vertebrae in abdominal X-ray CT images. Bone regions are extracted using binarization and morphological operators, and then spinal columns and ribs are obtained from the bone regions. The positions of intervertebral disks are estimated, and the spinal columns are divided into vertebra columns based on the estimated positions. The vertebral columns are identified on the basis of their relative positions and connectivity. This paper focuses on the extraction of the 12th thoracic vertebra (T12) observed in different areas of abdominal CT images. The proposed method was applied to 15 cases. The experimental results demonstrated that the proposed method was effective. |
