- 摘要：
PROBLEM TO BE SOLVED: To provide an X-ray imaging device, and an X-ray imaging method, capable of improving visibility of an object used in inspection.
SOLUTION: The device includes: an X-ray tube 3 an X-ray tube control part 6 to control tube voltage to be provided to the X-ray tube 3 a flat panel detector 4 to detect an X-ray radiated from the X-ray tube 3, and transmitted through a subject 1 a subtraction part 17 to obtain a subtraction image by conducting a subtraction process to measurement values of the X-ray by the flat panel detector 4 when a high voltage value is imparted to the X-ray tube 3, and measurement values of the X-ray by the flat panel detector 4 when a low voltage value is imparted to the X-ray tube 3 and an optimum voltage determining part 19 to determine a voltage value with which brightness difference between an image of a guide wire and an image of a bone part of the subject 1 on the substraction image gets maximum when the high voltage value imparted to the X-ray tube 3 is varied as the optimum voltage value.
