  • Method and device for X-ray exposure control
    Patent number: 6977989
    Abstract: The radiation applied to an object (input dose rate) during irradiation of the object by a radiation source (1) is limited during X-ray exposures. Pairs of values of a control curve which give rise to an input dose rate on the object to be examined which exceeds a predetermined maximum input dose rate are corrected by an arithmetic unit (76). This results in a corrected control curve whose entire length can be used for adjusting the desired tube parameters (tube voltage, tube current or load) without giving rise to the risk of exceeding the maximum input dose rate.

  • Method and device for X-ray exposure control
    Publication number: 20030133534
    Abstract: The invention relates to a method and a device for limiting radiation applied to an object (input dose rate) during irradiation of the object by means of a radiation source (1), notably during X-ray exposures. Pairs of values of a control curve which give rise to an input dose rate on the object to be examined which exceeds a predetermined maximum input dose rate are corrected by means of a calculated factor. This results in a corrected control curve whose entire length can be used for adjusting the desired tube parameters (tube voltage, tube current or load) without giving rise to the risk of exceeding the maximum input dose rate.
