摘要： A multiple x-ray energy level imaging system includes a scanning x-ray beam and two detector design having a first low x-ray energy sensitive detector and a second high x-ray energy sensitive detector. The low x-ray energy detector is placed next to or in front of the high x-ray energy detector. The low energy sensitive detector has small stopping power for x-rays. The lower energy x-rays are absorbed and converted into electrical signals while the majority of the higher energy x-rays pass through undetected. The high energy sensitive detector has a large stopping power for x-rays as well as it having a filter placed between it and the object to absorb the lower energy x-rays. In a second embodiment; a single energy sensitive detector is provided which provides an output signal proportional to the amount of energy in each individual x-ray it absorbed. It can then have an electronic threshold or thresholds set to select two or more energy ranges for the images. By having multiple detectors located at different positions, a dual energy laminography system is possible.

摘要： A readout circuit for an imaging detector that improves resolution and increases field of view in a display compared to traditional readout circuits. The readout circuit comprises two or more amplifiers that receive a row or column of outputs from the imaging detector. Subtraction circuitry, included in the readout circuit, receives the signals from the amplifiers, determines a fractional value of the sum of the signals, and subtracts the fractional value from each signal thereby producing both positive and negative signals. A rail to rail amplifier operating from a signale voltage supply eliminates one polarity of the signals making the signals unipolar. A combining circuit receives the unipolar signals and combines them to produce two readout circuit outputs that are transmitted to a computer to be displayed.
