1. A method for radiographic and nuclear imaging an object, wherein use is made of a device for radiographic and nuclear imaging of an object by means of x-ray imaging and gamma emission imaging, said device comprising: a support installation with opposed first and second support members, an x-ray source mounted on said first support member and adapted to emit an x-ray beam in an x-ray beam direction, an x-ray detector mounted on said second support member and adapted to image onto said x-ray detector the x-ray beam emitted by said x-ray source in said beam direction, wherein the first support member of the support installation is additionally provided with at least two gamma cameras that are each located adjacent the x-ray source, wherein each of said at least two gamma cameras comprises a collimator with one or more collimator openings and each of said at least two gamma cameras further comprises a gamma radiation detector, wherein each of said at least two gamma cameras has an associated field of view, wherein the fields of view of said at least two gamma cameras overlap partly, said overlap defining a focus volume that is seen by said at least two gamma cameras, the focus volume being located between the x-ray source and the x-ray detector so that said x-ray beam passes through the focus volume and the focus volume is seen by the x-ray detector, wherein the device comprises a computerized image processing unit linked to the x-ray detector and linked to said at least two gamma cameras, the imaging processing unit being programmed to reconstruct a gamma camera image and being adapted to fuse said gamma camera image with an x-ray image obtained with the x-ray detector into a fused image, wherein the device comprises a display adapted to display an x-ray image, a gamma radiation image, and/or a fused x-ray and gamma radiation image, wherein the support installation is adapted to provide a stationary acquisition position of the x-ray source, x-ray detector, and gamma cameras, during x-ray and gamma image data acquisition of x-ray and gamma radiation images respectively, that are fused into a fused image, and wherein the x-ray source, x-ray detector, and gamma cameras are maintained in a stationary acquisition position during x-ray and gamma image data acquisition of x-ray and gamma radiation images respectively, which images are fused into a fused image.
