Abstract: A system and method are provided for obtaining an improved visualization of bone objects comprised in a projection X-ray image. The projection X-ray image comprises bone objects which at least in part overlap. According to the system and method, a number of the bone objects are delineated by a contour, thereby obtaining a number of delineated bone objects. For each of the number of delineated bone object, a bone suppression technique is applied to the image to obtain respective bone image data individually showing the respective delineated bone object while suppressing shadows of obstructing objects. The bone image data generated for each of the number of delineated bone objects is used to generate an output image in which the bone objects do not overlap. An advantage of the system and method is that a non-overlapping, shadow-suppressed, presentation of the bone objects may be created from an X-ray image which was obtained by projectional radiography.
