A complex system for acquisition and generation of the image contains the detection unit, the memory unit, the units for measuring the period of idle run of the compensating frame and X-ray frame, the unit of the charge accumulation of compensating frame and X-ray frame, the unit for image processing, the control unit, X-ray source, the unit of cathode heating, the unit for controlling anode voltage, time commuter, the unit for controlling parameters of X-ray source, the unit for X-ray exposure meter, the detector of X-ray exposure meter, radiographic set, photoelectric converter, switching element, read-out circuit. analog-to-digital converter, excitation circuit, display, operator, console unit, radiographic control unit, memory of then characteristic of the dark current. The radiographic set is located between detecting unit and X-ray exposure meter connected to the unit of X-ray exposure meter. The latter in turn is connected to the mutually interconnected radiographic control unit and unit controlling the parameters of X-ray source connected to the unit of cathode heating, time commuter, and unit for controlling the voltage of anode and cathode. The control unit is connected to the units for controlling the voltage, time commuter unit of anode, and the unit of cathode heating. |
