Description
Technical field
The present invention relates to a kind of method for making and kapillary of PET detection point source.
Background technology
In the high resolution of two photon emission type computer tomography equipment (PET) detects, the making of point source is the committed step that this detects, this point source requires that the size in any direction is within 2mm, because point source makes of radioactive nuclide F-18 solution, and F-18 has very strong radiation, Radiation On Human body has harm.Must away from health when therefore making, and both hands are at lead glass latter acts.Existing method for making is glass capillary (surface without scale), the microsyringe of about 1mm with internal diameter, first drop on plastic paper by little for F-18 injection of solution one, the amount of drop must be controlled, ensure that the liquid column length that drop is formed in kapillary is less than 2mm, then with the siphonic effect of kapillary will form one end and is less than 2mm fluid column in drop tail pipe, the method is difficult to the amount controlling drop, and be also just difficult to the length controlling fluid column, the liquid column length often produced is greater than 2mm.
Summary of the invention
Amount in order to the radioactivity drop overcoming prior art is difficult to control, and the shortcoming that degree of accuracy is low, the invention provides a kind of PET detection point source preparation method and the kapillary that accurately can control radioactivity drop.
PET detects with some source preparation method, comprises the following steps:
1), prepare the kapillary that internal diameter is about 1mm, one end of kapillary has a millimeter scale mark, and the overall length of millimeter scale mark is more than 2mm;
2), a F-18 solution is released on plastic paper surface with syringe;
3), by the end thereof contacts drop edge of capillary fringe scale, kapillary slant setting, liquid sucks in kapillary because of siphonic effect, forms the fluid column being greater than 2mm;
4), be placed on table top after folded filter paper, have the kapillary lower end of liquid to be close to its surface suction, kapillary is vertically placed, and liquid is by filter paper sucking-off; The about minimizing 15mm per minute of speed that the fluid column of kapillary shortens;
5), operating personnel in the change of lead glass back side fluid column, take away when liquid column length is less than 2mm, kapillary penetrated soap and the tube head of kapillary is closed, complete point source make.
Further restriction: the liquid-column height that step 3) is formed is about 20mm.
Further restriction: be placed on table top after the folded filter paper in step 4) twice.
The kapillary of preparation PET detection point source, comprise pipe shaft, it is characterized in that: pipe shaft is provided with a millimeter scale, millimeter scale has 2 millimeter scales at least.
Further, the length of millimeter scale is 10mm, every millimeter of correspondence scale mark.
The present invention has can guarantee that liquid-column height is at below 2mm, the advantage that precision is high.
