Fundamental study on ultra-high-speed tomography system utilizing intense flash x-ray generators

A high-speed x-ray tomography system is useful for observing high-speed phenomena. The experimental setup for tomography consists of a tungsten-target x-ray generator, a tungsten collimator, and a computed radiography system. An object was exposed by a 2-mm-thick fun beam from the x-ray generator, and scattering x-rays from the slice plane were detected using an imaging plate through a tungsten collimator with hole diameters of 0.8 mm. Because the exposed dose for tomography was almost equal to those obtained using two intense flash x-ray generators, ultra-high-speed tomography could be performed.
