A computer program product for generating a density calibration curve from a digital x-ray image of an anatomic structure, the x-ray image including a wedge-shaped calibration phantom having length (L) and varying thickness (T) along the length, the computer program product comprising a computer usable medium having computer readable program code thereon, the computer readable program code comprising:
- (a) program code for generating an expected calibration curve for the wedge-shaped calibration phantom;
- (b) program code for measuring attenuation at a multitude of points in the x-ray image including the calibration phantom;
- and
- (c) program code for aligning the points measured in step (b) with the expected calibration curve generated in step (a), thereby generating a calibration curve for the image.
A system for generating a density calibration curve, the system comprising:
- (a) means for generating a digital x-ray image of an anatomic structure that includes a wedge-shaped calibration phantom having length (L) and varying thickness (T) along the length;
- (b) means for generating an expected calibration curve for the wedge-shaped calibration phantom;
- and
- (c) means for measuring attenuation at a multitude of points in the x-ray image including the calibration phantom;
- and
- (d) means for aligning the points measured in step (c) with the expected calibration curve generated in step (b), thereby generating a calibration curve for the image.
