摘要：
The invention relates to a device for X-ray diagnostics test object by scanning a beam of X-radiation and recording of digital scan results, obtaining a composite image and visualizing it on a monitor screen and can be used in mammography, to locate the different density of small non-palpable breast lesions. In digital scanning mammography comprising a source of X-radiation on the basis of X-ray tube, the compression unit, position-sensitive receiver of X-ray radiation transmitted through the breast tissue, comprising a multi-matrix solid state X-ray sensors and multichannel electrical signal readout chip with sensitive sensor elements, X-ray collimating optics system is disposed between the radiation source and the tissue gland, which input landmark IAOD actual focal spot x-ray tube and the output is directed to the entrance window of the position-sensitive X-ray receiver and has a profile corresponding to the profile of the sensitive area of the position-sensitive X-ray receiver, a scanning unit connected to the radiation source, the system of the collimating optics and the position-sensitive radiation detector , prostate digital image layout system, one input of which is connected to the output of the position-sensitive radiation detector, and the other - with a synchronization output of the scanning unit and the system processing and visualization of the composite image gland, whose input is connected to the input digital composite image composition system, a position-sensitive X-ray receiver comprises a quantum-sensitive solid-state X-ray sensors with a direct conversion, and each channel structure multichannel chipset It comprises a charge sensitive readout amplifier circuit with compensation of the dark current sensor, whose input is connected to a Exit corresponding sensitive element of the sensor, a comparator, one input of which is connected to the output charge sensitive amplifier and a second input connected to the block formation of the threshold pote
