title: [Magnification radiography with Circlex 0.1 mm ultra-microfocus].
abstract: 929 magnification radiographies of different rates of magnification were taken in 719 patients and 39 animals with the Japanese Circlex 0.1 mm ultra-microfocus tube. According to IEC 336/1982 documentation, tests on focus size, resolution, filtration effect of penumbra, filtration effect of contrast, background dispersion and space effect were done. The results showed that 0.1 mm ultra-microfocus could produce images of high quality.
