[Study of the characteristics of diagnostic X-ray equipment. 2. Relationship of spectral distribution of braking radiation and its dosimetric characteristics]. / Issledovanie kharakteristik rentgenodiagnosticheskikh izluchatelei. 2. Vzaimosviaz' spektral'nogo raspredeleniia tormoznogo izlucheniia s ego dozimetricheskimi kharakteristikami.

The results obtained by the method outlined in the paper for calculating dosimetric characteristics of a braking radiation spectrum are in rather good agreement with those of experimental studies and may be used for practical calculations instead of expensive and labour-consuming experimental methods for estimating the spectral characteristics of braking spectra.

[Spectral distribution of braking radiation in the tungsten anode X-ray tubes]. / Spektral'noe raspredelenie tormoznogo izlucheniia v rentgenovskikh trubkakh s vol'framovym anodom.

An analytical expression (mathematical model) of the spectral distribution of braking radiation in the in tungsten anode X-ray tubes has been derived. The discrepancy of the calculated spectra with experimental findings is no more than +/- 6%.

[Development of a system controlling x-ray diagnostic devices]. / Razvitie sistemy regulirovaniia rentgenodiagnosticheskogo apparata.

The purpose and criteria for efficiency (errors of anode voltage holding, tube current, and exposure) of the system controlling X-ray diagnostic devices are considered from theoretical and practical points of view. A microprocessor-controlled variant of the controlling system developed for numerous existing six-pulsed generators of the -3 type is outlined. The design and operation of the key circuit diagram of X-ray tube filament in the PEHA 50-6 microprocessor-controlled feeding device are shown in detail.

[Physical-technical possibilities of perfecting roentgenographic research]. / Fiziko-tekhnicheskie vozmozhnosti sovershenstvovaniia rentgenograficheskikh issledovanii.

The authors have classified factors that determine the quality of roentgenographic images and provided evidence for measures aimed at their improvement. It has been shown that it is conversion to an x-ray feeding device fitted out with microprocessor control that will make it possible to upgrade the quality of roentgenographic images and to reduce radiation loads of the patients.

[Development of a monitoring system for radiodiagnostic devices]. / Razvitie sistemy upravleniia rentgenodiagnosticheskikh apparatov.

The authors review the possibilities of the application of the "man-machine" theory to the radiodiagnostic unit. Show implementation of the theory with special reference to the basic purpose of the unit RENA 50-6 MP equipped with the microprocessor system of monitoring.

[Approaches and problems in the development of radiodiagnostic equipment]. / Puti i problemy razvitiia rentgenodiagnosticheskoi apparatury.

The authors analyze the current status of technical equipment of different sections of roentgenology. Note shortcomings in the units manufactured and in the equipment of the sections of radiodiagnosis. Make conclusions about the tasks the Association of Medical Physicists of this country face.

[Experience in the operation of an x-ray diagnostic complex with a remote-controlled stand]. / Opyt ékspluatatsii rentgenodiagnosticheskogo kompleksa s teleupravliaemym shtativom.

Functional potentialities of serial stands of the RUM-20 radiodiagnostic units were critically analyzed. The clinical use of remote-controlled stands of Rentgen-100T type was shown to hold promise.
