Abstract

The utility model provides a three-dimensional X-ray imaging device for rapid shooting, which comprises a base, a main bracket, an upper bracket, a lower bracket, a side bracket, a bulb tube, a diagnostic bed and a polyhedral detector, wherein the main bracket is installed on the base; the upper bracket, the lower bracket and the side bracket are installed on the main bracket; the main bracket do plus 90 to minus 20 degree rotation motion along the base, so as to ensure that the diagnostic bed has a standing body position and a lying body position; the bulb tube is fixed in an arc rail of the main bracket; the detector is fixed in an arc rail of the lower bracket; the bulb tube and the polyhedral detector do symmetrical motion around a detected object during exposure; and simultaneously the polyhedral detector performs rotation along a longitudinal axis.

Description

A kind of three-dimensional X line imaging device of quick shooting

Technical field

This utility model relates to medical instruments field, is specifically related to the three-dimensional X line imaging field in the medical image.

Background technology

Two dimension X line imaging is that diagnosis provides good analysis foundation; Along with development of science and technology; The doctor that appears as of computer x-ray layer radiography device provides better three-dimensional basis; Three-dimensional reconstruction image has also appeared at the medical image field, like the 3D image reconstruction of CT, MR, and the and for example imaging of the 3D in the ultrasonic examination.

As everyone knows, can rebuild the 3-D view of stereo display from the two-dimensional projection image data set that different directions is taken, therefore; From essential meaning; As long as keep the examinee position motionless relatively,, can obtain 3-D view through the poster processing soft even common X line photographic apparatus also can photograph the two dimensional image of different angles; But because human body such as is breathed at effects limit; The two dimensional image that will obtain a large amount of different angles in the short time is very difficult, and relevant in the past research worker C arm machine mode once on probation also once realized three-dimensional X line imaging with the mode that adds second detector; But be difficult in the practical application realize that topmost factor just is to take apace and obtains a large amount of two-dimensional projection image.

Summary of the invention

This utility model provides a kind of three-dimensional X line imaging device of quick shooting, can take the two-dimentional X line image of a large amount of different angles apace, thereby obtain three-dimensional X line image through post processing.

The technical problem that solves: the rapid data that shooting speed was taken and can be caught up with to the X line of making different angles apace reads.

The technical scheme that this utility model solves its technical problem is: this utility model proposes a kind of three-dimensional X line imaging device of quick shooting; Device is made up of base, main support, upper bracket, lower carriage, side stand, bulb, diagnostic bed and polyhedron detector; Main support is installed on the base; Upper bracket, lower carriage, side stand are installed on the main support, and main support is made+90 degree～-20 degree along base and is rotatablely moved, and makes diagnostic bed have two positions upright, for sleeping in concurrently; Bulb is fixed in the upper bracket arc track; Detector is fixed in the lower carriage arc track, and bulb and polyhedron detector are done the symmetry motion around subject during exposure, and the polyhedron detector is along the longitudinal axis rotation simultaneously.

The beneficial effect of this utility model is: obtain the two-dimensional projection image of a large amount of different angles fast, thereby obtain three-dimensional more clearly X line image, for doctor's diagnosis provides better analysis foundation.

Description of drawings

Below in conjunction with accompanying drawing this utility model is further specified.

Fig. 1 is the X line machine basic structure schematic diagram of this utility model.

Among the figure: 1. base, 2. main support, 3. upper bracket, 4. lower carriage, 5. side stand, 6. bulb, 7 diagnostic bedes, 8 detectors.

The specific embodiment

Fig. 1 is the X line machine basic structure schematic diagram of this utility model, and device is made up of base, support, bulb, diagnostic bed, detector and control circuit etc.Base is installed on the machine room ground; Main support can do along base+and 90 degree～-20 degree rotatablely move; Can make upright, two positions that crouch of diagnostic bed dual-purpose like this, the upper bracket major function is for supporting bulb and bulb being moved to foot end or head end, and the lower carriage major function is for supporting detector; The same upper bracket of motion mode, the side stand major function is for supporting diagnostic bed.

Bulb is fixed in the upper bracket arc track, and bulb can human body be that axis is done rotatablely moving of certain angle, and detector is fixed in the lower carriage arc track; With the human body is axis and bulb symmetry and the motion of work symmetry, and detector is the regular polygon structure, and polyhedron is done self to rotatablely move by longitudinal axis; The detecting plate flexible fastening is on polyhedral; Resiliently mounted purpose is done moment for exposure the time can make the exposure detecting plate rotatablely move and is paused, and every block of detecting plate back side stereotype covers, in order to avoid disturb other detecting plate during exposure; The quantity of detecting plate is how much indefinite polyhedral quantity is; Can not receive afterglow effect and reach detection data to read minimizing as far as possible on the basis that influences to satisfy, in reducing cost according to detecting plate materials used and reprocessing rate adjustment.

Three-dimensional X line image needs several different angles two dimensions X line image to rebuild to form, so during the single inspection, bulb and detector rotate around people's body axis and accomplish the several times exposure, the end exposure detector promptly rotates to next test surface at every turn.

Claims

1. three-dimensional X line imaging device of taking fast; Form by base, main support, upper bracket, lower carriage, side stand, bulb, diagnostic bed and polyhedron detector, it is characterized in that main support is installed on the base, upper bracket, lower carriage, side stand are installed on the main support; Main support is made+90 degree～-20 degree along base and is rotatablely moved; Make diagnostic bed have upright, two positions that crouch concurrently, bulb is fixed in the upper bracket arc track, and detector is fixed in the lower carriage arc track; Bulb and polyhedron detector are done the symmetry motion around subject during exposure, and the polyhedron detector is along the longitudinal axis rotation simultaneously.
