title: A medical record database in radiology.
abstract: A database system on the medical records of radiation therapy, computer tomographic and radioisotopic examinations of our department was created in Computing Center of Hokkaido University which has two remote terminals in the department. Old three filing systems which had been kept in three sections of our department independently since 1972 were integrated by the creation of the database. The main functions of our database management system are as follows; 1. data input through two minicomputers in the department; 2. data loading to the database from the minicomputers; 3. production of key word files and link files for generalised data handling. Seven files are defined in the database with total data of 30 Mega bytes at the end of 1981. Many programs for information retrieval and data processings were prepared and every member of the department can share both data and application programs registered. Outline and operation of the database system and some examples of data processings are reported.
