Abstract:
An X-ray generator, a measuring device using the same, and a method for obtaining an X-ray image are provided to obtain quantitative information of a blood inside a body by irradiating two X-rays through one X-ray tube. A window is formed in one side of a housing(10). Two anodes(20a,20b) are arranged in the center of the housing. Two cathodes(30a,30b) are arranged to face two anodes. Two high voltage generators(40a,40b) supply the high voltage to two anodes and two cathodes. Two X-rays are periodically irradiated to the measurement area through the window of the housing. Each high voltage generator has a signal generator.
