A method for transforming the spatial coordinates of an instrument into its corresponding X-ray projection image is provided. The method is based on the registration of the coordinates system of an X-ray beam imaging system with a location device by simultaneously recording the spatial coordinates and the X- ray projection images of a calibration tool. The data are then used to establish a transform that will be used to convert the spatial coordinates of an instrument into its corresponding X-ray image projection with the X-ray beam turned off. Furthermore, the image of the instrument can be simultaneously displayed with that of an object to be operated on to enable an operator to guide the instrument within the object.
