  • Patent number: 8199995
    Abstract: A method for mapping radiological image data from a source imaging system to a target imaging system obtains sensitometric response data for both the source and the target imaging systems and identifies an anchor point that relates a specified source signal value to a specified target signal value. A transform is applied to map a range of source signal values to a corresponding range of target signal values, wherein the transform is defined according to the sensitometric response data obtained for both the source and the target imaging systems and according to the identified anchor point.

  • Patent number: 7632016
    Abstract: A method for calibrating a digital X-ray detector executed at least in part by a control logic processor. A radiation sensor is disposed along the optical path that extends between a radiation emitter and the digital X-ray detector. A set of radiation beam conditions for X-ray generation is selected and digital image values from the digital X-ray detector are obtained in one or more iterations of providing a threshold signal to radiation control logic, the threshold signal corresponding to a predetermined exposure level, exposing both the digital X-ray detector and the radiation sensor to radiation and terminating the exposure according to a comparison of the threshold signal with a signal from the radiation sensor that indicates an accumulated radiation level, then obtaining the digital image values from the digital X-ray detector. One or more sets of calibration values are generated according to the obtained digital image values.
