Abstract

The invention relates to a system (100) and method (200) for generating an MR-based-virtual X-Ray, hereafter MRXR, image, said method (200) comprising: - acquiring (201) an initial set of one or several MRI images, wherein the MRI images comprised within said initial set are configured for enabling one or several 3D representations of a biological object; - processing (202) said one or several MRI images for increasing, notably for each of said one or several images, a visibility of each image region, if any, that represents a bone of the biological object - called hereafter "bone-region" - with respect to a visibility of another region that represents tissue of the biological object that is free of bone - called hereafter "non-bone region", and creating an image input set comprising the processed one or several images; - feeding (203) an improved bone visibility - hereafter IBV - 3D image into a cone-beam projection algorithm configured for performing an X-Ray-like projection, wherein the IBV 3D image is obtained from the processed one or several images of said input set, and wherein the cone-beam projection algorithm is configured for outputting said MRXR image; - providing (204) the outputted MRXR image via an interface.
