Referring to Fig. 1, one embodiment of the invention provides a kind of rotatable support structure 100.The rotatable support structure 100 is applied to
In CT (computed tomography, computed tomography) equipment, it is supported for the electronic component to CT equipment.
Optionally, electronic component includes at least bulb 200 and detector 300.CT equipment can carry out the region to be captured of target
Imaging, selectively, target can be patient, and region to be captured can be the lesions position of patient.Rotation support of the invention
The intensity with higher of structure 100 and rigidity can reliably support bulb 200 and detector 300, avoid rotatable support structure
Bulb 200 caused by deforming when 100 high-speed rotation and the position of detector 300 change, so that bulb 200 and detection
Device 300 is opposite always, in this way, the ray that bulb 200 issues can accurately be projeced into detector 300, guarantees imaging results
Accurately, it is diagnosed convenient for medical staff.
Referring to Fig. 1 to Fig. 6, in one embodiment, rotatable support structure 100 includes inner cylinder 110, outer cylinder 120 and more
Reinforcing rib 130.Inner cylinder 110 has opposite the first evacuation window 111 and the second evacuation window 112.Outer cylinder 120 is sheathed on inner cylinder
110 outside, for installing the bulb 200 and corresponding second of corresponding first evacuation window 111 between outer cylinder 120 and inner cylinder 110
Avoid the detector 300 of window 112.More reinforcing ribs 130 are arranged at intervals between inner cylinder 110 and outer cylinder 120, and connect inner cylinder
110 with outer cylinder 120.
It should be understood that inner cylinder 110 and outer cylinder 120 are hollow structure, and outer cylinder 120 is sheathed on the outside of inner cylinder 110,
To form double-layer structure.Space between the space, that is, inner cylinder 110 and outer cylinder 120 of double-layer structure, for installing bulb 200, visiting
Survey the electronic components such as device 300, high tension apparatus 500, collimator 400.Selectively, bulb 200, detector 300, high tension apparatus
500, collimator 400 etc. is mountable to the inner wall of outer cylinder 120, can also be installed on the outer wall of inner cylinder 110, certainly, can also pass through
Mounting plate is installed on inner cylinder 110 and/or outer cylinder 120.Illustratively, bulb 200, detector 300, high tension apparatus 500 are installed on outer
The inner wall of cylinder 120, also, detector 300 is installed on outer cylinder 120 by mounting plate.
Outer cylinder 120 and inner cylinder 110 in axial direction all have certain length, to increase the strong of inner cylinder 110 and outer cylinder 120
Degree and rigidity, bulb 200 and detector 300 easy to support etc. guarantee that support can so that inner cylinder 110 is unlikely to deform with outer cylinder 120
It leans on.It should be understood that the axial extending direction for referring to 110 central axis of inner cylinder.Moreover, by more between inner cylinder 110 and outer cylinder 120
Root reinforcing rib 130 connects, and reinforcing rib 130 can guarantee the synchronous rotation between inner cylinder 110 and outer cylinder 120 so that bulb 200 with
Detector 300 is opposite always.Meanwhile reinforcing rib 130 can also support inner cylinder 110 and outer cylinder 120, further increase inner cylinder 110
With the intensity and rigidity of outer cylinder 120.In this way, outer cylinder 120 is not easy to send out with inner cylinder 110 when 100 high speed rotation of rotatable support structure
Change shape, and to support bulb 200 and detector 300 etc. well, bulb 200 caused by avoiding because of deformation and detector 300 are wrong
Position, so that bulb 200 and detector 300 are opposite always.In this way, the ray that bulb 200 issues can accurately be projeced into detection
Device 300 guarantees the accurate of imaging results, diagnoses convenient for medical staff.
Since bulb 200 and detector 300 are mounted between inner cylinder 110 and outer cylinder 120, in order to not influence the hair of X-ray
It penetrates and receives, need to have on inner cylinder 110 and keep away bit space accordingly, so that X-ray can pass through, guarantee detector
300 Effect on Detecting.Specifically, inner cylinder 110 has opposite the first evacuation window 111 and the second evacuation window 112.First keeps away
Allow window 111 for avoiding the X-ray of the transmitting of bulb 200, so that the X-ray emitted for bulb 200 passes through, the second evacuation window
112 for the received X-ray of detector 300 for passing through, so that the X-ray for passing through target region to be captured projects detector
300。
Also, bulb 200 corresponds to the first evacuation window 111 and is arranged, and detector 300 corresponds to the second evacuation window 112
Setting.In this way, the X-ray that bulb 200 emits can be projected accurately by the first evacuation window 111, to guarantee that X-ray can be with
The region to be captured of target is completely covered, so that region to be captured can carry out complete imaging.Detector 300 can be accurate
The ray by the second evacuation window 112 is received, detector can not be projected to avoid the X-ray passed through behind region to be captured
300, detector 300 can receive the X-ray of completion, guarantee the imaging effect for treating shooting area.
In this way, 100 high-speed rotation of rotatable support structure, the X-ray that bulb 200 emits passes through first when CT equipment works
After avoiding window 111, across the region to be captured of target.It then passes through the X-ray in region to be captured can pass through the second evacuation
Window 112 projects on detector 300, and detector 300 handles the information of X-ray, with the region to be captured to target
Image imaging is carried out, diagnosis is facilitated.
Rotatable support structure 100 of the invention supports bulb 200 by the inner cylinder 110 and outer cylinder 120 for forming double-layer structure
With detector 300, also, inner cylinder 110 and outer cylinder 120 in axial direction have certain length, so that rotatable support structure 100
Intensity and rigidity with higher.In this way, when rotatable support structure 100 drives bulb 200 and 300 high-speed rotation of detector,
Inner cylinder 110 is not susceptible to deform with outer cylinder 120, and effective solution current rotatable support structure 100 deforms when rotating to be caused
Detecting structure inaccuracy problem so that bulb 200 and detector 300 are opposite always, the ray for guaranteeing that bulb 200 issues can
To be accurately projeced into detector 300, guarantee the accurate of imaging results, is diagnosed convenient for medical staff.
Optionally, the junction rounding off of reinforcing rib 130 and inner cylinder 110, the junction of reinforcing rib 130 and outer cylinder 120
Also rounding off.It in this way can be in order to processing and forming, simultaneously, additionally it is possible to improve reinforcing rib 130 and be connect with inner cylinder 110, outer cylinder 120
The intensity at place.
Referring to Fig. 1 to Fig. 3, it is possible to understand that, the first evacuation window 111 is a radial through-hole of inner cylinder 110.Certainly,
In other embodiments of the invention, the first evacuation window 111 penetrates through inner cylinder 110 at least along the axial direction of inner cylinder 110
One end.That is, the first evacuation window 111 can be the open slot not penetrated through in axial direction, or along axial side
To the through slot of perforation.It can guarantee that the first evacuation window 111 has sufficiently large space in this way, avoid stopping bulb 200X ray
Transmitting.
It should be understood that the second evacuation window 112 is a radial through-hole of inner cylinder 110.Certainly, in of the invention other
