Abstract
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 has a base for providing mechanical stability, a mesh with a central cut-out overlaid on the base, inserts positioned in the cut-out, and a carrier for housing the composite phantom. A digital image of the phantom is processed to compute x-ray system image quality measurements.
