| Abstract: | Because ICT can truly tell us much information about the shape or size of the internal blemish and its physics,it is widely applied to industry inspection.The homogeneity of the X-ray irradiation field has an important influence on the photo quality.So it is necessary to probe into the offect of the target angle,the tube-voltage,the distance and filter-material upon the homogeneity of the X-ray irradiation field. |

| Keywords: | irradiation field target angle tube-voltage distance filter-material industrial computerized tomography |
