Abstract
Superimposed X-ray and video images can be obtained by acquiring the respective images from the optically equivalent points in space. One or more mirrors may be used to acquire the images and direct them towards the camera. The images can then be combined by warping one onto the other.
Claims7
A method of correlating an optical image with an X-ray image by superimposing one image on the other, said method comprising the steps of:
- directing a source of X-ray energy from a point in space through an object of interest onto a detector plane, creating an X-ray image on the detector plane;
- positioning the optical center of an optical camera at a point in space equivalent to the projection center of the X-ray source;
- obtaining an optical image of the object of interest from an optically equivalent point in space;
- superimposing the X-ray and optical images;
- and
- warping one of the images onto the other, such that said images coincide in magnification and such that said images have a common image plane with each other.
