Arc-shaped multi-focal point fixed anode gate controlled ray source

An arc-shaped multi-focal point fixed anode gate controlled x-ray source, comprising an arc-shaped x-ray source housing, an x-ray tube bracket, a plurality of fixed anode reflected x-ray tubes and a plurality of gate controlled switches;

• wherein two ends of the respective fixed anode reflected x-ray tube are an anode end and a cathode end respectively, the anode end of the respective fixed anode reflected x-ray tube generates an x-ray beam by using a reflected fixed anode target, and a gate is arranged close to the cathode in the respective fixed anode reflected x-ray tube;
• the plurality of fixed anode reflected x-ray tubes are fixed on the arc-shaped x-ray source housing through the x-ray tube bracket, and focal points of the plurality of fixed anode reflected x-ray tubes are distributed on a distribution circle;
• and the plurality of gate controlled switches and the plurality of fixed anode reflected x-ray tubes are connected correspondingly.
