A prototype γ-camera has been constructed from a slice of lithium-drifted germanium 44 × 44 mm in area and 6·5 mm in sensitive thickness. Positional information is obtained using the orthogonal strip principle, the inherent spatial resolution being 3 mm. Data are presented on energy resolution, uniformity, linearity of image and spatial resolution. The application to imaging distributions of 99Tcm in rats and humans is demonstrated, and comparisons on picture quality and background made (using the identical sources) with a conventional Anger system.
