The fan-shaped x-ray beam that second end 40 emits is downward, and is located in two parallel faces.It should be understood that Fig. 4 is merely to diagram
Illustrate, the fan-shaped x-ray beam that anode first end 20 and anode second end 40 emit can simultaneously upwards, the face parallel positioned at two
It is interior.In addition, the collimator before the first target 23 and the second target 43 is omitted in Fig. 4.
In the embodiment as shown in fig.5, the fan-shaped x-ray beam that anode first end 20 emits is upward, anode second end 40
The fan-shaped x-ray beam of transmitting is downward.In the present embodiment, 40 end face of 20 end face of anode first end and anode second end towards phase
Instead, as shown in figure 5, left end end face is towards oblique upper, right end end face is obliquely downward.The first target 23 and are also omited in Fig. 5
Collimator before two targets 43.
In one embodiment, when looking up along anode lengths side, the first of 211 injection of first collimator outlet is fan-shaped
The coverage area for the second fan-shaped x-ray beam that the coverage area of X-ray beam and the second collimator port 411 project can not weigh

Subtended angle is α1, the subtended angle for the second fan-shaped x-ray beam that corresponding second collimator port 411 of the second target 43 projects is α2, two X
The angle of beam lap is α3, as shown in Figure 6 b.Then effective X-ray beam angle α in the specific embodiment is not less than α1
Or α2, corresponding relationship are as follows:
α=α1+α2-α3
The fan-shaped x-ray beam of biparting pencil of forms x ray generator both ends transmitting, which is not overlapped or misplaces, can expand X-ray sector
The field angle of beam, and intersection enhances X-ray output dose, also ensures while increasing scanning range tested
The picture quality of target.
In the case where the subtended angle met the requirements, the fan-shaped x-ray beam of biparting pencil of forms x ray generator both ends transmitting is overlapped
When can be enhanced X-ray output dose, enhancing detection signal improves detection accuracy.
In one embodiment, the subtended angle adjacent boundary of the fan-shaped x-ray beam of biparting pencil of forms x ray generator both ends transmitting
Just it being overlapped, then X-ray beam field angle is the sum of the subtended angle of both, thus the transmitting of biparting pencil of forms x ray generator
The subtended angle expanded of fan-shaped x-ray beam.
In the above embodiments, the subtended angle α for the first fan-shaped x-ray beam that first collimator outlet 211 is projected1With second
The subtended angle α for the second fan-shaped x-ray beam that collimator port 411 projects2It is identical.In another embodiment, first collimator goes out
Mouth 211 and the second collimator port 411 are different, the subtended angle α for the first fan-shaped x-ray beam that first collimator 21 projects1With second
The subtended angle α for the second fan-shaped x-ray beam that collimator port 411 projects2It is not identical.

Shell 6 is connected for the anode to be fixed on inside the shell 6.Anode handle 5 can also be arranged for connection high-voltage electricity
Source, that is, the anode of high voltage power supply can directly be electrically connected anode handle 5, particularly, can be directly grounded for negative high voltage power source.Sun
Pole handle 5 can be a part of anode, and in other words, anode is integral piece.In another embodiment, 5 company of can be of anode handle
It is connected to the component of anode.
The B-B sectional view of anode handle 5 is as shown in Fig. 2, can following with external fluid dielectric coolant by cooling joint 52
The mode of " insulating oil+oil pump+laminar flow radiator " combination can be selected in ring radiator.In addition, the outer end face of anode handle 5 can be with
Conduction-type radiator, preferably heat-pipe radiator or semiconductor chilling plate are installed.Both modes, which are used in combination, can be enhanced heat dissipation
Effect improves the stability and reliability of X-ray tube.
In one embodiment, anode handle 5 may include cooling duct 51, be configured to flow through cooling medium, such as Fig. 1
It is shown, it should be appreciated that cooling duct 51 can have other forms, and Fig. 1 is not illustrated in detail only for concise.Cooling duct 51
It flows through cooling medium to be advantageous, this can help the temperature for reducing anode handle 5 and anode.For example, use insulating oil as
Cooling medium recycles insulating oil using oil pump, and insulating oil flows the heat for taking away anode handle 5 in the channel inside anode handle 5,
