<p>An x-ray bone densitometry system (30) includes a table (50) having a movable support surface configured to support a patient, an x-ray source (52) and an x-ray detector (54) positioned on opposite sides of said support surface so that a patient positioned on the support surface is between the x-ray source (52) and the x-ray detector (54), the x-ray source (52) and the x-ray detector (54) being aligned in a fixed relationship relative to each other such that x-rays emitted from the source (52) impinge the x-ray detector (54), the x-rays that impinge the detector (54) producing dual energy scan data, a processor (38) coupled to the x-ray source (52), the x-ray detector (54) and the table (50) and configured to actuate movement of said support surface, to receive the dual energy scan data, to extract from the dual energy scan data, dual energy image data and single energy image data, and to store the dual energy and the single energy image data in respective data records for selective display, and at least one display (44) connected to the processor (38) for displaying the dual energy and/or the single energy image data. Methods for display single energy and dual energy images on the display (44), and for determining the best scan parametric values for the patient are also provided.</p> |
