In PET-CT, the integration of PET and CT is the problem that first PET-CT device solves, the application of CT is relatively ripe, in use the function of actual requirement CT and PET can be used by integrator, can also independently use separately, such covering device can meet the purposes of CT, can also meet the use of PET, and it is its main function that certain PET-CT combines use.Desirable PET-CT should be, when PET and CT are combined the function that just can realize PET-CT, can realize separately the function of CT and PET after PET-CT divides out.
In the development process of PET-CT, generally adopting PET is partly independent development technology, and CT partly need be with ripe CTJi producer as oem vendor.Because CT shapes, the organic associating of PET and CT becomes the difficult problem that needs solve so.
Utility model content
In order to solve the organic combined problem of PET and CT in prior art, this utility model provides the campaign-styled PET-CT device of a kind of PET.
The purpose of this utility model is to provide the campaign-styled PET-CT device of a kind of PET.
The campaign-styled PET-CT device of PET of the present utility model comprises: PET main frame, CT main frame, examinating couch, numerical control two-dimensional movement base 4; Wherein, the detector rings of PET main frame and CT main frame is positioned on same axis; It is motionless that CT main frame and examinating couch are fixed on ground; PET main frame is arranged on numerical control two-dimensional movement base.
Examinating couch comprises holder and bed board; It is motionless that holder is fixed on ground; Bed board is arranged on holder, and bed board is the detector rings through PET main frame and CT main frame along axis direction.Bed board can move along axis direction on holder.
Numerical control two-dimensional movement base can complete the motion of both direction: both can, along the translational motion of axis direction, can also complete the elevating movement perpendicular to axis direction.The motion of this both direction can link, very little perpendicular to the scope of the elevating movement of axis direction, is mainly used for compensating for bed board stretches out the rear sagging distortion causing.
Further, this utility model also comprises cover laser measuring device for measuring, is arranged on PET main frame, and is positioned under bed board, and laser measuring device for measuring is connected to numerical control two-dimensional movement base.Laser measuring device for measuring measure bed board and stretch out after at the deflection perpendicular to axis direction, then send data to numerical control two-dimensional movement base, numerical control two-dimensional movement base drives PET host motion, do two-axle interlocking in the axial direction with in direction perpendicular to axial direction, complete scanning and also compensated the error that the sagging distortion of bed board brings.
When CT main frame checks, the bed board of examinating couch carries out the horizontal movement along axis direction, realizes CT scan; Complete after CT scan, the bed board of examinating couch reaches maximum position, does not retract; Then laser measuring device for measuring measure bed board and stretch out after at the deflection perpendicular to axis direction, then send data to numerical control two-dimensional movement base, numerical control two-dimensional movement base drives the relative CT host motion of PET main frame, do two-axle interlocking in the axial direction with in direction perpendicular to axial direction, realize PET scanning and also compensated the error that the sagging distortion of bed board brings.
Advantage of the present utility model:
This utility model adopts PET main frame is placed on numerical control two-dimensional movement base and does two-axle interlocking, laser measuring device for measuring measure bed board and stretch out after at the deflection perpendicular to axis direction, can realize CT scan, can realize again PET scanning, realize scanning and also compensated the error that the sagging distortion of bed board brings.This device is applicable to any CT, can be as the CT subsystem of PET-CT.
