Method carry out the qualitative and quantitative study of cell and molecular level to the bioprocess under condition of living organism, right on a molecular scale
Organism physiology, the change of pathology carry out real-time, dynamic, at body, noninvasive imaging technique.It is research targeting, specific
The key of molecular probe and medicine, core technology.Multi-modal molecular image technology can realize the advantage of different images equipment
Complementation, the imaging results making acquisition is more accurate, more reliable.Clinical practice is it was demonstrated that multi-modal molecular medicine image documentation equipment is at weight
Examine the morning of big disease early control, the formulation of therapeutic scheme, the checking of result for the treatment of play an important role in assessing.Positive electron is sent out
Penetrate fault imaging (Positron Emission Tomography) PET and there is very high detectivity, and knot can be provided
X ray Tomography (X-ray Computed Tomography) the X-ray CT of structure information is merged into individual equipment PET-
CT, is widely used.
In PET-CT, the integration of PET and CT is the problem that first PET-CT device solves, and the application of CT is relative
Maturation, in use the function of actual requirement CT and PET can integrator use, moreover it is possible to is each independently operated, this
Sample set of device i.e. can meet the purposes of CT, can also meet the use of PET, and it is that it is main that certain PET-CT is used in combination
The function wanted.Preferable PET-CT should be, just can realize the function of PET-CT when PET and CT is combined, when
PET-CT can be implemented separately the function of CT and PET after separating.
In the development process of PET-CT, the general PET of employing part is self owned development technique, and CT part need to be with becoming
Ripe CT machine producer is as OEM supplier.Owing to CT has shaped, then the organic associating of PET and CT becomes need
A difficult problem to be solved.
Content of the invention
In order to solve organic combined problem of PET and CT in prior art, the present invention provides a kind of campaign-styled PET-CT of PET
Device.
It is an object of the invention to provide a kind of PET campaign-styled PET-CT device.
The PET campaign-styled PET-CT device of the present invention includes: PET main frame, CT main frame, examination couch, numerical control two-dimensional movement
Base, laser measuring device for measuring；Wherein, the detector rings of PET main frame and CT main frame is positioned on same axis；CT main frame and inspection
Looking into bed, to be fixed on ground motionless；PET main frame is arranged on numerical control two-dimensional movement base, and described laser measuring device for measuring is arranged on PET
It on main frame, and is positioned under bed board.
Examination couch includes fixing seat and bed board；It is motionless that fixing seat is fixed on ground；Bed board is arranged on fixing seat, bed board edge
Axis direction passes through the detector rings of PET main frame and CT main frame.Bed board can move along axis direction on fixing seat.
Numerical control two-dimensional movement base can complete the motion of both direction: both can translational motion in the axial direction, also
Can complete to be perpendicular to the elevating movement of axis direction.The motion in the two direction can link, and is perpendicular to the liter of axis direction
The scope of fall motion is very little, and the sagging deformation causing after being mainly used for stretching out for bed board compensates.
Laser measuring device for measuring is connected to numerical control two-dimensional movement base.Laser measuring device for measuring measurement bed board is being perpendicular to after stretching out
The deflection of axis direction, then sends data to numerical control two-dimensional movement base, and numerical control two-dimensional movement base drives PET master
Machine moves, and in the axial direction and be perpendicular on axial direction do two-axle interlocking, i.e. completes scanning and also compensates for the sagging change of bed board
The error that shape is brought.
When CT main frame checks, the bed board of examination couch carries out horizontal movement in the axial direction, it is achieved CT scans；
After completing CT scanning, the bed board of examination couch reaches maximum position, does not retracts；Then after laser measuring device for measuring measurement bed board stretches out
It is being perpendicular to the deflection of axis direction, then sending data to numerical control two-dimensional movement base, numerical control two-dimensional movement base band
Dynamic PET main frame is relative to CT host motion, in the axial direction and be perpendicular on axial direction do two-axle interlocking, i.e. realizes PET
Scanning also compensates for the error that bed board sagging deflections brings.
Advantages of the present invention:
The present invention uses to be placed on PET main frame and does two-axle interlocking on numerical control two-dimensional movement base, and laser measuring device for measuring measures bed board
It is being perpendicular to the deflection of axis direction after stretching out, can realize that CT scans, can realize that again PET scans, i.e. realizing scanning also
Compensate for the error that bed board sagging deflections brings.This device is applicable to any CT, can serve as the CT subsystem of PET-CT
System.
