Visualization of components of a mixed COM/HA stone. A. Digital photograph of stone, on 1 mm grid. B. Micro CT slice through middle portion of stone; arrow indicates ring of high attenuation (hydroxyapatite). Gray material outside this ring had attenuation value in the range for COM. C. 3-D surface rendering from micro CT displaying surface topology. D. 3-D surface rendering with transparent shell to show 3-D localization of hydroxyapatite within stone.
