Abstract
A high resolution high-energy x-ray digital imager suitable for patient x-ray diagnosis and the location of bony landmarks in high energy radiation therapy. The imager employs an array of sensor chips which need not lie in a plane in order to provide overlap of non-active components and direct readout (non - CCD) signal processing electronics incorporating a switched capacitor per detector readout to sense a short x-ray pulse. The switching prevents dark current from discharging sensing capacitors and corrupting the data signal.
