GRID APPARATUS AND X-RAY DETECTOR

摘要

PURPOSE: A grid apparatus and an x-ray detector are provided to reduce a time and effort for removing the noise of a grid by simply implementing a noise removal algorithm. CONSTITUTION: In a grid apparatus and an x-ray detector, an X-rays is scattered from a subject. An X-ray absorbing material(204) absorbs the X-rays. A permeable material(202) is formed between the absorbing materials. The permeable material transmits the X-rays. The absorbing material and the permeable material form a line pattern. The line pattern forms a certain angle from the pixel line pattern of a detector.
