Detailed description of the invention
Below with reference to accompanying drawing, described in detail the specific embodiment of the present invention and embodiment, described specific embodiment only in order to explain the present invention, is not intended to limit the specific embodiment of the present invention.
Mobile CT scanning means of the present invention is a kind of new scan mode, which can make sick bed transfixion in scanning process, allow CT self just can complete whole scanning processes, without the need to controlling sick bed, and this scan mode should be able to realize the tomography, the helical scanning that meet each position of whole body.Be move horizontally with the scan ring in frame the advance and retrogressing that replace sick bed on the whole, realize scanning in particular circumstances.
As shown in Figure 1, Fig. 1 is that Mobile CT scanning means of the present invention moves horizontally schematic diagram, this Mobile CT scanning means comprises frame 110 and scan ring 120, the axial line horizontally set of described scan ring 120, the left and right sides of described frame 110 is respectively arranged with horizontal translational components 130, described horizontal translational components 130 is connected with the left and right sides of described scan ring 120, described scan ring 120 is moved forward and backward for the relatively described frame 110 of axial direction along described scan ring 120, label a is the state of described scan ring 120 when moving to described frame 110 front end, label b be described scan ring 120 be in described frame 110 middle time state, label c is the state of described scan ring 120 when moving to described frame 110 rear end, the bottom of described frame 110 is also provided with wheel 140, so that mobile described support 110.
In the preferred implementation of Mobile CT scanning means of the present invention, shown in composition graphs 2 and 3, Fig. 2 is the top view of Mobile CT scanning means of the present invention, Fig. 3 is the axonometric chart of Mobile CT scanning means of the present invention horizontal translational components used, described horizontal translational components 130 comprises motor 131, ball-screw 132 and nut 133 thereof, Connection Block 134 and load-bearing bearing 135, described load-bearing bearing 135 be arranged in parallel with described ball-screw 132, described scan ring 120 can be connected on described Connection Block 134, described Connection Block 134 is arranged on described nut 133, described motor 131 is connected to one end of described ball-screw 132, described nut 133 is engaged on described ball-screw 132, for drive described ball-screw 132 to rotate at described motor 131 process in, drive described Connection Block 134 along the axial direction movable described scan ring 120 back and forth of described load-bearing bearing 135 by described nut 133.
