    摘要: 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.

    摘要: Apparatus and method for electronically reading planar two dimensional .beta.-ray emitter-labeled gel electrophoretograms. A single, flat rectangular multiwire proportional chamber is placed in close proximity to the gel and the assembly placed in an intense uniform magnetic field disposed in a perpendicular manner to the rectangular face of the proportional chamber. Beta rays emitted in the direction of the proportional chamber are caused to execute helical motions which substantially preserve knowledge of the coordinates of their origin in the gel. Perpendicularly oriented, parallel wire, parallel plane cathodes electronically sense the location of the .beta.-rays from ionization generated thereby in a detection gas coupled with an electron avalanche effect resulting from the action of a parallel wire anode located therebetween. A scintillator permits the present apparatus to be rendered insensitive when signals are generated from cosmic rays incident on the proportional chamber. Resolution for concentrations of radioactive compounds in the gel exceeds 700 .mu.m. The apparatus and method of the present invention represent a significant improvement over conventional autoradiographic techniques in dynamic range, linearity and sensitivity of data collection. A concentration and position map for gel electrophoretograms having significant concentrations of labeled compounds and/or highly radioactive labeling nuclides can generally be obtained in less than one hour.
