THE 'DOZA' ELECTRONIC ANALOG COMPUTER FOR ESTIMATING DOSE FIELDS IN AN IRRADIATED PERSON'S BODY,
Abstract
A new special-purpose analog computer, the 'Doza', was developed by the Moscow Scientific Research Institute of Computer Construction (NII Schetmash) for the purpose of estimating isodose patterns and for studying the distribution of dose fields in anatomical cross-sections. The 'Doza' calculates the distribution of a dose field inside a multifield-irradiated circle as a function of the source radiation energy, source-skin distance, and irradiation-field area. The total doses are estimated at the intersections of a rectangular coordinate net with 1-cm squares. The 'Doza' includes: an analog computer proper which calculates, according to a specified algorithm, the percent depth of the dose, at a specified point of the cross-section, caused by one irradiation field; input units which receive all initial data as voltages; output units which yield digital information and also patterns drawn on paper; a sync unit which ensures synchronous input of quantities that vary in the course of solution; and a control panel.
