Acquire two-dimensional images and film loops (or CineLoops) of still and dynamic mouse anatomy. Able to guide needle-based procedures with real-time imaging, for the injection of chemicals, retroviral DNA, or other biochemical compounds into tissue regions that can be seen clearly within the image area. Extraction of fluid and/or cells under image guidance for biopsy, bio-assays and analysis is also possible. Export still images, export video loops, measure lengths, areas and circumferences of ellipses and user-defined polygons.
