Referring to Fig. 1, be provided with micrometer head 60 in the position of boss 46 1 sides, be used for adjusting the position of detector assembly 30 and being locked.Micrometer head 60 is fixed on ring rotation platform or the disk 10 by bearing 82.In a kind of optimal way, be subjected to displacement when rotating in order to prevent detector assembly 30 with ring rotation platform or disk 10, be respectively arranged with a micrometer head 60 in the position of boss 46 symmetrical both sides.Thus, when rotating with ring rotation platform or disk 10, two micrometer heads 60 can produce auto-lock function, can effectively avoid displacement to take place at detector assembly 30.In addition, on boss 46, also be provided with trip bolt 81, after detector assembly 30 location are regulated, trip bolt 81 is screwed in the arc bolt hole 48, thereby detector assembly 30 further be fastened on ring rotation platform or the disk 10.
Describe referring to Fig. 5-7 pair of structure according to the detector module 50 of one embodiment of the present invention.As shown in Figure 5 and Figure 6, in one embodiment, detector module 50 comprises base plate 51; As the circuit board that has the high energy crystal 52 of high energy detector array, it is arranged at the front of described base plate 51, promptly towards the one side of radiation source; The circuit board that has the low energy crystal 54 as the low energy detector array; And dividing plate 53, it is arranged between the circuit board 54 of high energy crystal circuit board 52 and low energy crystal.By adopting the circuit board 54 of above-mentioned high energy crystal circuit board 52 and low energy crystal, thereby form the dual-energy detector array structure.
In addition, as shown in Figure 5, the further integrated collimating apparatus that is provided with in the front of detector array architecture is used for the ray that emits from radiation source is collimated and proofreaies and correct.As shown in Fig. 6 and 7, collimating apparatus comprises the pedestal 55 with upper and lower relative broach shape structure; The dividing plate 56 that anti-ray penetrates, the dividing plate 56 that described a plurality of anti-rays penetrate are separately positioned in a plurality of upper and lower relative broach on the pedestal 55, are each detector crystal between two adjacent broach.Thus, by adopting said structure, formed a kind of collimating apparatus with lattice structure.In addition, as shown in Figure 5, this collimating apparatus also comprises the plate 58 that the anti-ray in the face of radiation source one side penetrates is set, and between plate 58 that described anti-ray penetrates and described pedestal 55 cushion block 57 can also be set, and is used to increase and be adjusted in plate 58 that anti-ray penetrates and the distance between the described pedestal 55.
In said structure, owing to collimating apparatus directly is integrated in the detector module 50, thereby make the structure of detector assembly 30 compact more, removed the collimation device simultaneously from respect to the complexity of detector module, loaded down with trivial details adjusting position fixing process.The component parts of above-mentioned detector module 50 is fitted together by screw 59, constitutes a detector module 50 thus.
Need to prove that in the above-described embodiments, detector module 50 adopts circuit board 52 that has the high energy crystal and the dual intensity detector that has the circuit board 54 of low energy crystal.But the present invention is not limited to this, and can adopt monoenergetic detector or multipotency detector.
Referring to Fig. 2, the detector module 50 of above-mentioned formation is installed in the horizontal full-length groove 44 of the arc vertical panel 41 of regulating positioning pedestal 40, thereby constitutes detector assembly 30.As shown in Figure 2, in one embodiment, in adjusting positioning pedestal 40 outer setting radome 92 is arranged, it is used for covering adjusting positioning pedestal 40 and described detector module 50, to prevent and to eliminate external environmental factor, for example electromagnetic wave and temperature, humidity etc. are to the influence of positioning pedestal 40 and described detector module 50.Radome 92 and detector crystal 93 relative one sides have elongated window 94 and enter into detector module 50 to allow radiation ray.Because radome 92 is detector module 50 sealing, so detector module 50 can not be subjected to the interference of electromagnetic wave and temperature, humidity, thereby guarantees detector assembly 30 working stabilities.In order to control and regulate the energy level that incides the radiation ray on the detector module, 94 places are provided with metal forming at window, and for example aluminium foil 95 is connected on the window 94 with its covering.
1-3 is described further the position fixing process of detector assembly 30 according to the present invention with reference to the accompanying drawings.
As previously mentioned, detector module 50 is installed in the horizontal full-length groove 44 of the arc vertical panel 41 of regulating positioning pedestal 40, thereby constitutes detector assembly 30.Compare with the technical scheme that detector array of the prior art is arranged on the positioning support, because detector module 50 is with the step part 44A of horizontal full-length groove 44 positioning reference as detector module 50, thereby is convenient to fast and easily detector module 50 positioned.Simultaneously, realized location, and exempted in the prior art loaded down with trivial details adjusting and location detector array to detector module 50 owing to adopt to regulate positioning pedestal 40.
Next, detector assembly 30 is installed on the ring rotation platform or disk 10 of CT examination system 1.At this moment, unclamp whole trip bolts 81, any one micrometer head 60 of initial rotation retreats it, and then rotates another micrometer head 60, makes it push away boss 46 and advances.Under the guiding of the spacing leading block 70 of detector assembly 30 this moment in the arc guide groove 47 of boss 46, the track that limits along arc guide groove 47 rotates around the target spot A of radiation source 20, thereby realizes the accurate location to detector assembly 30.After the adjusting and location that realize detector assembly 30, trip bolt 81 is screwed in the arc bolt hole 48, thereby detector assembly 30 further is fastened on ring rotation platform or the disk 10.Thus, finish the adjusting of detector assembly 30 and accurate location.
Though some embodiment of this present general inventive concept are shown and illustrate, those skilled in the art will appreciate that, under the situation of principle that does not deviate from this present general inventive concept and spirit, can make a change these embodiment, scope of the present invention limits with claim and their equivalent.
