Distortion corrector for digital radiograph |
摘要 |
A dental X-ray image sensor provided with a cross mark that is opaque to radio waves on the corner of a digital radiography sensor surface renders a computer program to recognize true dimension and to rescale any distortion due to angulational position error in a conventional X-ray digital radiograph system.
