Claim:
1. A method for evaluating dose performance of a radiographic imaging system with respect to image quality using a phantom, a channelized hotelling observer module as a model observer, and a printer, a plaque, or an electronic display, said method comprising: scanning and producing images for a plurality of sections of the phantom using the radiographic imaging system, wherein the plurality of sections represents a range of patient sizes and doses and wherein the plurality of sections of the phantom contain objects of measurable detectability; analyzing the images to determine detectability results for one or more of the objects within the images of the plurality of sections of the phantom, wherein said analyzing comprises using a channelized hotelling observer (CHO) module as a model observer; and displaying, via the printer, the plaque, or the electronic display, a continuous detectability performance measurement function using the determined detectability results.
