Abstract: PURPOSE: An X-ray generator and an operation method thereof are provided to implement high quality X-ray image even in case of low radiation by controlling an exposure time and a focusing electrode. CONSTITUTION: An X-ray generator comprises an X-ray tube(2), a high voltage generator(1), an X-ray detector(3), and a sequence controller(4). The high voltage generator passes a current to the filament of the X-ray tube to heat it. The heated filament radiates electrons to form an electron cloud around the filament. The electron cloud is moved to a target and is collided with it by high electric filed which is generated from high voltage difference. The collision of between the electron cloud and the target radiates X-ray.
