Abstract: A method of calibrating a frontal 2D image of a pelvis of a patient is disclosed. Frontal and lateral 2D images are received, where a fiducial marker is positioned on the patient's suprapubic region during image capture. A first distance of the fiducial marker from the imaging detector is determined based on the fiducial marker's measured diameter in the frontal image. A second distance of the fiducial marker from a coronal plane of the pelvis is determined based on the fiducial marker's measured diameter in the lateral image. The second distance is corrected based on a rotational offset of the patient in the lateral image. A third distance of the coronal plane from the imaging detector in the frontal image is determined from the first distance and corrected second distance. A calibration factor for the frontal image is calculated from the third distance and used to scale the frontal image.
