Abstract: A rotary anode unit includes a target formed of a first metal material and a target support body formed of a second metal material, formed in a flat plate shape, and having first and second surfaces. A thermal conductivity of the second metal material is higher than a thermal conductivity of the first metal material. A first recessed portion is formed in the first surface at the outer part of the target support body. The target is disposed in the first recessed portion. A second recessed portion configured to define a flow path for allowing a coolant to flow is formed in the second surface at the inner part of the target support body. A thickness of a first region where the first recessed portion is formed is larger than a thickness of a second region where the second recessed portion is formed.

Abstract: A method for generating an x-ray image in color includes selecting three-sets of x-ray images in gray scale acquired with x-rays having different energy spectra, assigning basic colors RGB to the three-sets, and displaying the x-ray image in color with RGB signals generated. A system for generating an x-ray image in color includes an x-ray generator configured to generate at least three sets of x-rays with different energy spectra, an x-ray detector, a controller, a computer, and a color display. The computer is configured to generate three sets of x-ray images from output data of the x-ray detector acquired for x-rays with different energy spectra, assign RGB and display an x-ray image in color. A non-transitory computer readable medium stores an instruction, when the instruction is executed by a processor, cause the processor to perform the method for generating an x-ray image in color.
