Description

A kind of test die body for SPECT rotation center

Technical field

The utility model relates to the detection alignment technique fields SPECT more particularly to a kind of SPECT rotation center to test mould Body.

Background technique

With the arrival in " precisely medical treatment " epoch, medical imaging device is fast-developing, accurate image, molecular imaging, micro- Wound interventional therapy and Low emissivity metering and " double low " technology of low contrast medium concentrations rise in the prevention of disease, diagnosing and treating Increasingly important role is arrived.Accurate medical treatment is based on the analysis of clinical physiology index and bio-molecular level come for patient The demand of individual determines the strategy of diagnosis, prognosis and treatment, and single photon emission tomographic imaging equipment (SPECT) is realized from shape State can not only reflect the function of organ, tissue to function, the conversion shown from gross anatomy to molecule biochemistry on a molecular scale It can, moreover it is possible to by rebuilding faultage image dynamic, whole body and the three-dimensionally variation of observation internal organs and disease.SPECT is in medical field It is widely used, for example obtains very big strut in the imaging of the internal organs such as heart, bone, kidney, liver, thyroid gland, become One of capital equipment in clinical medicine diagnosis.

In order to which SPECT can normally be run, needs periodically to detect each performance indicator of SPECT, pass through survey Actual performance index is measured, measurement result and standard requirements are compared, once non-compliant requirement, machine are then stopped using, is needed Machine is corrected and is safeguarded immediately.

The picture quality of SPECT faultage image is not only related with the softwares such as image reconstruction that it is used and correction, also with spy The rotating hardware of head is related, and the drift of SPECT rotation center is exactly that detection probe machinery center of rotation with projection centre is overlapped degree Performance indicator.

The side of the current standard of each group hair-weaving cloth and report in the world and company, each SPECT manufacturer detection rotation center Method is different.Such as National Electrical Manufacturers Association (National Electrical Manufactures Association, NEMA) in NU 1-2007, rotation center test uses three point sources (point source drug is Tc-99m), There is strict demand in point source placement position；The rotation of General Electric Company (General Electric Company, GE) product The test at center then uses a point source, draws appropriate point source with syringe and is put in parallel notch end, and adjusts a little In the circle of display screen；The test of SIEMENS (Siemens Company) product rotation center then uses 5 point sources, point source pendulum Putting position has strict demand.

As described above, the rotation center detection method that different tissues, different company are formulated is different, actually detected In, the difference for requiring and using can only be put using required different number of point sources, different point sources according to different situations Die body, this brings great inconvenience to the detection correction work of testing staff, also formulates national standard and unified detection to China Method brings very big challenge.
