A system for collecting and processing information has been developed in the basis of the model "Elektronika" D3-28 computer. An interface between the computer and diagnostic instruments has been designed and manufactured. The software for the system has also been devised. The programs allow, besides making calculations in accordance with some concrete working methods, to smooth out curves, to eliminate overshoots, to print out the file data on patients, etc. The main advantages of this system are its low cost and the elimination of manual work in numbering curves and data processing, which increases the working capacity of radiological equipment.
