Abstract:
A fluoroscopy method for obtaining an image of an object (11) together with radiopaque intervention means (30), the method using a rotating X-ray source (8) and a corresponding detector (6) with the object and the intervention means positioned between the X-ray source and the detector, the method further using processing means, said method comprisingsubjecting the object to the X-rays (9) originating from the X-ray source: positioning the intervention means (30) within the object (11), such that they intercept at least a part of said X-rays (9); using the processing means (40) to present a spatial position of the intervention means (30) with respect to the object; characterized by a cone beam (9) being used as the X-ray source, a two-dimensional detector (6) being used as the detector and further comprising: generating a light beam propagating substantially in a plane adjacent to an edge of the cone-beam, spatially delineating the cone-beam it its exterior.
