Tomography Data

Ultrasound reflection tomography based on the compound scan principle, allows one to produce reflectivity images with high quality and reproducibility. In this paper, methods are discussed on how to extract additional physical parameters from the same set of reflection data for medical applications. Experimental results from a phantom object and in-vivo measurements illustrate the capabilities of such tomographic reflection Systems.

Objective Prism

The unique 70-cm meniscus-type telescope of the Abastumani Astrophysical Observatory supplied with two objective prisms and the seeing conditions characteristic at Mount Kanobili (Abastumani) permit us to obtain stellar spectra of a high quality. No additional design to improve the “climate” immediately around the telescope itself is being applied. The dispersions and photographic magnitude limits are 160 and 660Å/mm, and 12–13, respectively. The short-wave end of spectra reaches 3500–3400Å.
