FIELD: medicine. ^ SUBSTANCE: invention refers to medical equipment, namely to X-ray image forming systems. An image forming apparatus comprises a detector, a memory unit for storing a dark current characteristic of the detector, a first time sensor for measuring the first period from applying a shift voltage to a converter element to the beginning of converter element accumulation for image acquisition, a second time sensor for measuring the second period from the beginning of accumulation before termination thereof, an arithmetic element for accumulation quantity and an image processing unit for equilibrium correction of the image acquired from the accumulation quantity of dark current. The image forming system contains the image forming device and a radiation generator for generation of the radiation. The method of controlling the image forming device consists in measuring the first period applying a shift voltage to the converter element to the beginning of the converter element accumulation for image acquisition, measuring the second period from the beginning of accumulation to termination thereof, calculating accumulation quantity of dark current included in accumulation. The dark current characteristic and the first and second periods are used to carry out equilibrium correction of the image acquired by the calculated accumulation quantity of dark current. The invention also refers to a data carrier that stores the program for controlling the image forming device. ^ EFFECT: application of the invention allows for high-quality X-ray image without increase in cost and dimensions of the device. ^ 9 cl, 11 dwg |
