    摘要: A system and method for radiographic inspection of airfoil structure on aircraft includes a radiation source located on one side of the airfoil structure and an X-Y scanning device located on an opposing side of the airfoil structure. The X-Y scanning device is positioned to receive radiation from the radiation source. A radiation detector is mounted on the X-Y scanning device so as to be moveable relative to the airfoil structure along t two mutually orthogonal axes. In operation, the radiation detector is moved in a predetermined raster pattern while the radiation source is emitting radiation. This allows a large area to be inspected with single positioning of the X-Y scanning device, thereby improving throughput. The radiation detector converts impinging radiation into electrical signals, and a computer system processes the signals to generate radiographic images of the airfoil structure.

    摘要: A method of radiographic inspection of an object includes the steps of: providing a radiation source and a radiation detector located on opposite sides of the object; positioning the radiation detector to receive radiation transmitted through the object from the radiation source; radiographically imaging an region of interest of the object with the radiation source and the radiation detector, using an set of initial imaging parameters, to produce a test image; obtaining at least one quality measurement of the test image; comparing the quality measurement to predetermined image quality limits; and in response to the quality measurement exceeding the predetermined image quality limits, changing at least one of the initial imaging parameters to generate a new set of image parameters. The process may be repeated iteratively until a final set of imaging parameters is obtained.
