Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Please refer to Fig. 1, an embodiment of the invention provide a kind of computed tomograph scanner system 100.The detector 140 that this computed tomograph scanner system 100 comprises scan track 120, sends the light source 130 of probing light and receive through the probing light of scanning object 110.Wherein, light source 130 and detector 140 are assemblied on this scan track 120.Scan track 120 is regular polygon scan track 120.When the limit number of regular polygon is even number, the limit number being equipped with power supply 130 is equal with the limit number being equipped with detector 140.When the limit number of regular polygon is odd number, the limit number being equipped with power supply 130 differs a limit with the limit number being equipped with detector 140.Corresponding with the limit being equipped with light source 130 limit that can receive through the probing light of scanning object 110 is equipped with detector 140.Light source 130 and detector 140 move on described regular polygon track 120.
Light source 130 and detector 140 move back and forth on the limit at its place, run into corner's stop motion or return movement.Light source 130 and detector 140 move with traditional along compared with circuit orbit or helical orbit on the limit at its place, and mechanical precision requires lower, and it is easier that machinery realizes.Light source 130 is assemblied on regular polygon scan track 120, and the light direction of light source 130 can carry out suitable adjustment according to the position of itself and scanning object 110 and detector 140.
In this embodiment, regular polygon scan track 120 is regular hexagon scan track 120.Now orthohexagonal limit number is even number, and the limit number being equipped with power supply 130 and the limit number being equipped with detector 140 are three limits.In other embodiments, according to concrete demand, regular polygon scan track 120 can be designed to regular pentagon, positive heptagon, octagon etc., not limit herein.
Light source 130 is assemblied on the adjacent limit of three of regular hexagon scan track 120, and detector 140 is assemblied on remaining three the adjacent limits of regular hexagon scan track 120.Light source 130 quantity be assemblied on regular hexagon scan track 120 is 0,1,2 etc., it is 0,1,2 etc. that detector 140 is assemblied in quantity on regular hexagon scan track 120, only needs to guarantee have corresponding detector 140 to receive through the probing light of scanning object 110.When an assembling light source 130, after light source 130 irradiates on a certain position, move to the next position and continue to irradiate, until arrive corner.When assembling multiple light source 130, each light source 130 moves and irradiates scanning object 110 in certain distance.Detector 140 moves to the corresponding position receiving probing light through scanning object 110 along with the change of light source 130 irradiation position.
Please refer to Fig. 2, it is the second embodiment of the present invention.Present embodiments provide for a kind of computed tomograph scanner system 200.The key distinction of this embodiment and the first embodiment is: light source 230 is assemblied on three of regular hexagon scan track 220 limit not adjacent to each other, and detector 240 is assemblied on remaining three limits not adjacent to each other of regular hexagon scan track 220.In other embodiments, light source 230 can also be assemblied on six limits of regular hexagon scan track 220, and detector 240 is assemblied on six limits of regular hexagon scan track 220, does not limit herein.
Please refer to Fig. 3, it is the 3rd embodiment of the present invention.Present embodiments provide for a kind of computed tomograph scanner system 300.The key distinction of this embodiment and the first embodiment is: regular polygon scan track 320 is regular pentagon scan track 320.Now, the limit number of regular pentagon is odd number, is equipped with a limit number limit more than the limit number being equipped with detector 340 of power supply 330.Adopt that light source 330 is assemblied on three adjacent edges, detector 340 is assemblied in assembling mode on residue two adjacent edges, and suitably the light direction of adjustment light source 330 to guarantee that corresponding detector 340 can receive its probing light through scanning object 110.
Please refer to Fig. 4, it is ground of the present invention four embodiments.Present embodiments provide for a kind of computed tomograph scanner system 400.The key distinction of this embodiment and the 3rd embodiment is: the limit number one article limit fewer than the limit number being equipped with detector 440 being equipped with power supply 430, adopts that light source 430 is assemblied on adjacent two adjacent edges, detector 440 is assemblied in assembling mode on residue three adjacent edges.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
