Abstract:
A technique for establishing texture metrics and bone mineral density (BMD) within an anatomical region of interest. A digital imaging system is used to acquire a standard digital X-ray image with a wide field of view. The standard digital X-ray image is used to guide the imaging system to obtain an image of a region of interest. The standard digital X-ray image is used to calculate various texture metrics, such as a length of a fracture. A dual-energy digital X-ray image of the region of interest is acquired. The dual-energy digital X-ray image is corrected for scatter. The BMD of the region of interest may be established from the scatter-corrected dual-energy digital X-ray image. The BMD, the texture metrics, and/or the scatter-corrected dual-energy X-ray image may be displayed on the standard digital X-ray image.
