title: Serial cerebral angiography in stereoscopic magnification.
abstract: A ceiling x-ray tube support with synchronous up and down movements is described for obtaining two parallel x-ray beams with a short focal-film distance. Stereoscopic cerebral angiography is performed with direct serial magnification using a heavy-duty anode tube with a 0.1 mm focus. This technique combines the advantages of magnification and stereoscopic angiography. Small arterial and venous changes can be observed clearly in three dimensions. The usefulness and limitations of this method are discussed using clinical and experimental data.
