| Research Abstract |
1. A segmentation method for vertebral bone regions was developed. In the method, five landmarks are detected on each vertebra and these landmark positions are used to initialize the following multi-atlas-based segmentation method which can segment regions of all vertebrae simultaneously.
2. A rough detection and displaying method for bone metastasis regions is developed. The method is based on the temporal subtraction between the recent CT images and the older CT images.
3. A database which includes 35 subjects with multiple bone metastases was established. In each subject, the metastasis regions were inputted manually in a 3-dimensional manner.
