Image of FIG. 1.
FIG. 1.

Block diagram of the compact quasimonochromatic flash x-ray generator with a cold-cathode monochromatic diode.

Image of FIG. 2.
FIG. 2.

Circuit diagram of the two-stage surge Marx generator. The generator produces twice the potential of the condenser charging voltage.

Image of FIG. 3.
FIG. 3.

Schematic drawing of the flash x-ray tube with a rod-shaped molybdenum target and a disk graphite cathode.

Image of FIG. 4.
FIG. 4.

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.

Image of FIG. 5.
FIG. 5.

Variations in the tube voltage and current with a charging voltage of (a) −50 kV, (b) −60 kV, and (c) −70 kV.

Image of FIG. 6.
FIG. 6.

X-ray outputs detected using a combination of a plastic scintillator, a photomultiplier, and the zirconium filter.

Image of FIG. 7.
FIG. 7.

Images of the x-ray source of lines obtained using a pinhole camera with changes in the charging voltage.

Image of FIG. 8.
FIG. 8.

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.

Image of FIG. 9.
FIG. 9.

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.

Image of FIG. 10.
FIG. 10.

Radiogram of a vertebra. Fine structure of the vertebra were visible.

Image of FIG. 11.
FIG. 11.

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.

Image of FIG. 12.
FIG. 12.

Angiograms of a rabbit heart. Fine blood vessels of approximately 100 μm were visible.
