[Improving the retrieval of information from scientific research works in the field of medical roentgenoradiology].

A subject thesaurus covering investigations pursued at the Moscow Research Institute of Roentgenoradiology (Ministry of Health of the RSFSR) has been worked out for data retrieval. Each subject heading is provided with indices of the International Classification of Inventions (MCI), national classifications of inventions (NCI), Universal Digital Classification (UDC), Branch Automated System of Scientific Medical Information (BASSMI), Medinform, and the State Automated System of Scientific-Technical Information (SASSTI). The subject thesaurus is necessary for the detection of relevant information in the BASSMI and Medinform data banks and in patent forms.
