  • Distortion correction method for linear scanning X-ray system
    Patent number: 7873142
    Abstract: Imaging apparatus comprises a radiation source arranged to generate a divergent imaging beam and an associated radiation detector mounted on a C-arm which can rotate. A first drive is arranged to move the radiation source and the detector relative to a subject in a scanning direction to generate output signals from the detector, thereby performing a scan generating image data containing distortion in a direction transverse to the scanning direction. A second drive is arranged to rotate the C-arm, to change the orientation of the radiation source in a direction transverse to the scanning direction incrementally between repeated scans, thereby to generate a plurality of sets of image data.
    Type: Grant
