Abstract
The invention relates to a phantom for testing nuclear medicine instruments, such as for positron emission tomographs (PET), single-photon emission computed tomographs (SPECT) or even for autoradiography. The phantom contains a solid body that spontaneously emits gamma radiation or positrons. The disadvantages of a phantom filled with a radioactive liquid can be routinely overcome therewith. The inventive phantom can be produced with structuring smaller than 1 mm, and in particular even smaller than 0.1 mm. The inventive phantom can be used for the first time both for positron emission tomography (PET) and for autoradiography, since the phantom can emit both gamma radiation and positron radiation.

15. A method for production of a phantom system, with the following steps:
-
at least two layer-like solid bodies are machined in such a way that they contain, at least in parts, 2-dimensional or 3-dimensional defined structuring in the range <
1 mm;
the layer-like, structured solid bodies are arranged as a layered system in such a way that this simulates at least partly a morphological structure;
the layered system is irradiated to make it radioactive. - View Dependent Claims (17)
