The CT apparatus irradiates a minute amount of X rays to capture body images. In order to capture high definition images and to control or shield unnecessary X rays from surroundings, tungsten or molybdenum thin sheets are used by making the best use of their high specific gravity and shielding property.
The CT apparatus irradiates a minute amount of X rays to capture body images. W wires and W thin sheets are used as filaments of electron beam generating sources to produce X rays by making the best use of their high heat resistance and high electric resistance.
Molybdenum rods are used inside the X-ray tube to generate X rays of the CT apparatus by making the best use of their high heat resistance and high strength.
