FIELD: radiology.
SUBSTANCE: system for control X-ray scanning comprises a plurality of emitters and at least one receiver located opposite each other. Each X-ray emitter comprises an anode (A) connected to one power supply (Aps), as well as a grid (G) and a cathode (K). Each cathode is connected to at least one controller (CLR1), which controls anode current (IA), and contains a comparator (COMP), which has the required anode current (DIA) as a reference value. This allows avoiding calibration of required value of cathode current, maintaining accurate state of all X-ray emitters and reducing time of transition between switching on and off.
EFFECT: faster scanning and higher accuracy of scanning.
