[0042] 参照图4、图7、图8、图9和图10所示,PET-CT机架安装对准的方法及步骤如下: [0042] Referring to FIGS. 4, 7, 8, 9 and 10, PET-CT gantry installation and method for aligning the steps of:

[0043] (1)将组装好的所述CT中心指示组件1安装于CT机架旋转部上,即将所述支撑板11 通过螺钉121、螺钉122固定在CT机架旋转部2预留的接口上,用于指示CT旋转中心,此时所述激光器13发射的激光粗略位于CT机架旋转部2的中心,所述激光器I3向PET方向发射一束激光; [0043] (1) assembled to the central CT indicating assembly 1 is mounted on the rotating gantry portion CT, about to the support plate 11 by a screw 121, the screw 122 is fixed in a CT gantry rotation unit 2 reserved interface , the center of rotation CT for indicating, when the laser light emitted by the laser 13 roughly in the center of the CT gantry rotation unit 2, the laser emits a beam of laser light to I3 PET direction;

[0044] ⑵将所述PET中心指示组件3安装于PET机架4预留的接口上,用于指示PET探测器的中心位置;将PET机架4移至需要安装的位置上,调整所述PET机架4的位置,使所述激光器13发射的激光光斑靠近所述第一中心板31上第一中心指示器33的位置,调节所述激光器13 上的聚焦换131,使所述第一中心板31上的光斑达到最小; [0044] ⑵ the PET Center indicating assembly 3 is mounted on the frame 4 reserved interface PET, the PET detectors for indicating a center position; the position of the PET gantry 4 on the need to move, to adjust the PET position of the rack 4, the laser 13 emitted laser spots closer to the position indicator 33 on the first center of the first center plate 31, adjusting the focus of the laser 13 on transducer 131, the first spot on the center plate 31 is minimized;

[0045] (3)用手慢慢转动所述CT机架旋转部2,若此时所述激光束未与CT旋转中心完全重合,则所述光斑在第一中心板31上的轨迹是一个圆,则可通过调节四维调整台14上的调节旋钮,使得CT机架旋转部2转动时所述光斑位置不动,此时所述光斑位于CT的旋转中心上; [0045] Slowly turn the CT gantry rotary section 2, at this time when the laser beam CT is not fully coincide with the center of rotation, then the light spot tracks on the first plate 31 of the center (3) is a hand circle can be adjusted by adjusting the knob on the four-dimensional table 14, so that the CT gantry rotation unit 2 is rotated to the position when the light spot does not move, when the spot is located on the center of rotation of the CT;

[0046] (4)移动所述PET机架4,调整PET机架4前端的支撑点41和支撑点42,使所述光斑对准第一中心指示器33; [0046] (4) moves the PET gantry 4, adjusting the PET gantry 41 and the supporting point of the front end of the supporting point 424, the center alignment of the first indicator light spot 33;

[0047] (5)保持所述第一中心板31的位置不动,取下所述第一中心指示器33,使所述激光器13发射的激光光斑可到达并靠近所述第二中心板32上第二中心指示器34的位置,调节所述聚焦环131,使所述光斑达到最小。 [0047] (5) holding the position of the first central panel 31 does not move, remove the first center indicator 33, so that the laser spot emitted by the laser 13 can reach the center and adjacent to the second plate 32 the second position indicator 34 on the center, the focus adjusting ring 131, so that the light spot is minimized. 调节PET机架4后端的支撑点43、支撑点44的高度,使所述光斑对准第二中心指示器32。 Adjusting the rear support points 4 PET gantry 43, the height of the support point 44, the center of the spot aligned with the second indicator 32. _ _

[0048] 需要说明的是,在调节所述支撑点43、支撑点44前,也可对CT旋转中心进行再次确认,操作方法与上述确认方法相同,即用手慢慢转动CT旋转部,若所述激光光斑位置不动, 表明此时激光光斑仍在CT旋转中心上;若转动CT旋转部时所述激光光斑在后中心板上的轨迹是个圆,则需再次调节四维调整台14上的调节旋钮,使得CT转动时所述激光光斑位置不动。 [0048] Incidentally, in adjusting the support points 43, 44 before the supporting point, can reconfirm the CT rotation center, similar to the above method of operation confirmation method, i.e. slowly rotating the rotary portion CT hand, if the position of laser spot does not move, indicating that the laser spot is still the rotational center CT; CT if the rotation of the rotating portion of the laser spot in the center of trajectory plate is a circle, re-adjustment is required dimensional adjustment table 14 knob, so that the spot position of the laser CT rotation does not move.

[0049] 需要说明的是,所述激光到达第二中心板32位置时所在位置已很接近第二中心指示器34,因而对于所述支撑点43、支撑点44的调节仅是很微小的幅度,故而在调整过程中可基本保持第一中心板31的位置不动。 [0049] Incidentally, the laser light reaches the second position 32 where the center position of the plate very close to the center of the second indicator 34, and thus with respect to the support point 43, the anchor 44 is only adjusted very small amplitude , can therefore remain substantially in the first center plate 31 does not move the position of the adjustment process. 若在调节过程中有略微影响,则可以重复上述步骤,直至PET与CT中心完全同轴。 If there is a slight influence in the adjustment process, the above steps may be repeated until complete coaxial center PET and CT.
