<p>Method for digital calibration of an X-ray installation, comprising a table (1), an arch (3) supporting, at its two ends, means (4) for emitting an X-ray beam and means (5) for receiving the said beam, means (7, 8) for storing, processing and displaying the images, and means (9) for controlling the movements in the said installation. A calibrated grid (10) is used to evaluate the parameters relating to the coefficients of enlargement and of distortion of the image produced. The said parameters are transferred to a computer (8) for image analysis and to a computer (9) controlling the positioning of the installation. <IMAGE></p> |
