Block diagram of the compact quasimonochromatic flash x-ray generator with a cold-cathode monochromatic diode.
Circuit diagram of the two-stage surge Marx generator. The generator produces twice the potential of the condenser charging voltage.
Schematic drawing of the flash x-ray tube with a rod-shaped molybdenum target and a disk graphite cathode.
Irradiation of rays using a monochromatic zirconium filter. Bremsstrahlung rays are not emitted in the opposite direction to that of electron acceleration, and molybdenum rays are left using a zirconium filter.
Variations in the tube voltage and current with a charging voltage of (a) −50 kV, (b) −60 kV, and (c) −70 kV.
X-ray outputs detected using a combination of a plastic scintillator, a photomultiplier, and the zirconium filter.
Images of the x-ray source of lines obtained using a pinhole camera with changes in the charging voltage.
X-ray spectra from the molybdenum target with the filter. The spectra were measured using a transmission type spectrometer with a lithium fluoride curved crystal.
Radiograms of tungsten wires of 50 and 100 μm in diameter coiled around a pipe made of polymethyl methacrylate. A 50 μm-diameter wire could be observed.
Radiogram of a vertebra. Fine structure of the vertebra were visible.
Radiogram of water falling into a polypropylene beaker from a glass test tube. The stop-motion image of water was obtained by monochromatic flash radiography.
Angiograms of a rabbit heart. Fine blood vessels of approximately 100 μm were visible.
