Abstract: A method for image quality assessment of a digital radiography system extracts and isolates one or more individual targets from a phantom image, then obtains operator responses by displaying each isolated individual target and recording a corresponding operator response related to image appearance for each isolated individual target. The accumulated operator responses are stored to obtain the image quality assessment.

Abstract: A phantom for use in measuring characteristics of a digital radiography imaging system has at least one substrate having a patterned foil layer. The pattern in the foil layer being defined by a plurality of apertures within which the substrate is exposed.

Abstract: An apparatus for aligning a radiation source with an image receiver. The apparatus includes first and second light sources. The first light source is coupled to the image receiver and actuable to direct a first pattern of light toward the radiation source. The second light source is coupled to the image receiver and actuable to direct a second pattern of light toward the radiation source. The spatial relationship of the two patterns on or near the radiation source indicates a predetermined alignment position for the radiation source.
