    摘要： A timer circuit for an X-ray imaging system having an X-ray generator used to generate images of a patient. The circuit includes a current sensor connected between a main power system and a circuit interrupter, wherein the circuit interrupter is also connected to the X-ray generator. The circuit also includes a timing device coupled between the current sensor and a control computer. The timing device is triggered when a current level detected by the current sensor exceeds an idle current level wherein X-rays are not generated by the X-ray generator. The timing device then measures a time period that the idle current level is exceeded. When the measured time period exceeds a predetermined time period by 10%, the circuit interrupter is activated to turn off current flow to the X-ray generator.

    摘要： In a method for estimating the remaining life span of an X-ray radiator that has been installed in an X-ray apparatus and is operational, under specified test conditions and at time intervals, a measurement value that is indicative for the remaining life span of the X-ray radiator is determined and stored in a memory. A forecasted progression of future measurement values is then forecasted from the instantaneous measurement value and previous measurement values that were determined under identical test conditions, which also are stored in the memory. The forecasted remaining life span of the X-ray radiator is then determined based on the forecasted progression and a limit value that is associated with the individual X-ray radiator, which is stored in the memory.

    摘要： A neural network prediction has been provided for predicting radiation exposure and/or Air-Kerma at a predefined arbitrary distance during an x-ray exposure; and for predicting radiation exposure and/or Air-Kerma area product for a radiographic x-ray exposure. The Air-Kerma levels are predicted directly from the x-ray exposure parameters. The method or model is provided to predict the radiation exposure or Air-Kerma for an arbitrary radiographic x-ray exposure by providing input variables to identify the spectral characteristics of the x-ray beam, providing a neural net which has been trained to calculate the exposure or Air-Kerma value, and by scaling the neural net output by the calibrated tube efficiency, and the actual current through the x-ray tube and the duration of the exposure. The prediction for exposure/Air-Kerma further applies the actual source-to-object distance, and the prediction for exposure/Air-Kerma area product further applies the actual imaged field area at a source-to-image distance.

    摘要： Method and instrument for measuring X-ray radiation, for generating a value representative of the radiation in the form of an electric signal, such that the radiation at the measurement instance is caught by two photo-electric units each receiving the radiation after its passage through filters having mutually different degrees of absorption. The radiation value is computed on the basis of a ratio between the two generated electric signals. Adaptation of the signal intensity to a processing range is made, which constitutes a lesser part of the total intensity range of the signals generated by the radiation, by means of an amplifier device with a variable degree of amplification, by sensing the signal intensity after the amplifier device. The amplifier device is designed as a pre-amplifier which is maintained at a fixed degree of amplification and is in series therewith, terminal amplifiers, which are adjusted in their degrees of amplification in order to give the signals said intensity adapted to the operational range. By varying the signal processing, the method/instrument may be adapted for generation of measurement values correlated to parameters including kVp, X-ray dose, exposure time and curve-shape.
