<p>An image quality test phantom tool is provided for use in the calibration and standardization of digital x-ray fluoroscopy and radiography systems. A composite phantom (10) has a base (12) for providing mechanical stability, a mesh (14) with a central cut-out overlaid on the base, inserts (15,16,20,22) positioned in the cut-out, and a carrier (24) for housing the composite phantom. A digital image of the phantom is processed to compute x-ray system image quality measurements. <IMAGE></p> |
