Abstract: A digital radiography system for imaging a subject. A support structure, coupled to an X-ray source and an X-ray imaging detector, is rotatable about a first axis and is linearly moveable. The X-ray source and the X-ray imaging detector are also rotatable about second and third axes, respectively, to provide an operator with a number of degrees of freedom to move the X-ray source and the X-ray imaging detector to different positions relative to a subject. Further, the system has means for coupling an operator control interface and a display to the X-ray source for permitting an operator to rotate them about a fourth axis so that the operator control interface and display are accessible to the operator such that the position of the operator does not have to change when the positions of the X-ray source and the X-ray detector are changed.
