ABSTRACT:
Best scan parametric values of a x-ray bone densitometry scanning system for a particular patient is selected according to a thickness of the patient. An operator initially selects scan parametric values of a fast mode scan which is the recommended default, and then commences the fast mode scan. At the initial portion of the scan, the x-ray thickness of the patient is measured. If the measured x-ray thickness is not greater than a predetermined limit of the fast mode scan, the fast mode scan is continued. If the measured x-ray thickness is greater than the predetermined limit of the fast mode scan, the x-rays are turned off, and the operator is given a choice of continuing with the fast mode scan or restarting with a slower mode scan. If the operator selection is to continue, the fast mode scan is continued. If the operator selects restarting, a slower mode scan is commenced.
