| Abstract: | Because of its advantages such as painless,highly efficiency and so on,XCT is applied extensively to the medical treatment.The homogeneous of the X-ray irradiation field makes an important influence on the photo's quality.The C language is used to establish computer procedure,whose parameters come from the technique parameters to the medical X-ray computerized tomography,in order to inquiry how target angle,tubevoltage,distance and filter-material make an influence on the homogeneous of the X-ray irradiation field from reflect target. |
