The invention relates to a single-target-surface multi-focus-point X-
ray bulb tube. The single-target-surface multi-focus-point X-
ray bulb tube comprises a
bulb tube housing consisting of a bulb tube head and a straight bulb tube, wherein a plurality of berylium windows uniformly arranged in a round shape by taking the center of a closed end surface as a center are arranged on the closed end surface of the bulb tube head; a positive
electrode consisting of a positive
electrode bulb tube and a positive
electrode straight tube is arranged in the bulb tube housing; the positive electrode bulb tube is positioned in the bulb tube head, and the positive electrode
straight tube is positioned in the straight bulb tube; and a bearing, a positive electrode seat, a rotor and a
copper bush are arranged between the positive electrode
straight tube and the straight bulb tube in sequence, the outer wall of the positive electrode straight tube is closely connected with an inner ring of the bearing, an outer ring of the bearing is closely connected with the inner wall of the positive electrode seat, the rotor is embedded into the inner wall of the
copper bush, and one end, close to the positive electrode bulb tube, of the
copper bush is connected with the positive electrode straight tube through an outer iron cover. The single-target-surface multi-focus-point X-
ray bulb tube further comprises two negative electrodes arranged in different positions. According to the single-target-surface multi-focus-point X-ray bulb tube, multiple pairs of X-rays in different positions can be exposed within a short time. The single-target-surface multi-focus-point X-ray bulb tube is comprehensive and accurate in imaging, simple in structure and wide in application range.
