| 摘要 |
The invention relates to a test body for nuclear medicine devices, such as, for example, for positron emission tomographs (PET), single photon tomographs (SPECT) or also for autoradiography. The test body comprises a solid body which itself emits gamma radiation or positrons. The disadvantages of a test body filled with a radioactive fluid can thus be routinely overcome. According to the invention, the production of said bodies permits structures smaller than 1mm, in particular, smaller than 0.1mm. Said test body can be used for positron emission tomography (PET) as well as for autoradiography as the test body can emit gamma radiation as well as positrons. |
