X-RAY COMPUTED TOMOGRAPHY APPARATUS |
摘要 |
PROBLEM TO BE SOLVED: To provide an X-ray computed tomography apparatus capable of separately providing intended some in multiple energy bands of X-rays.SOLUTION: An X-ray tube generates X-rays to be emitted to a test object. A high voltage generation part generates multiple tube voltages to be applied to the X-ray tube so that the X-ray tube generates the X-ray. A first control part controls the high voltage generation part to switch multiple X-rays whose each band having different energy that are generated from the X-ray tube in response to the tube voltages. A filter part is arranged between the X-ray tube and the test object, and includes filters respectively corresponding to the X-rays. A second control part controls the filter part in synchronization with switching of the X-rays to switch the filters respectively corresponding to the X-rays so that the X-ray generated from the X-ray tube is filtered by the filter corresponding to the X-ray. |
