[Expert system of choosing lower limb (thigh) prosthesis and diagnosis of the quality of prosthetics (II)].

The authors review an expert system (ES) of diagnosing the prosthetics quality, elucidate problems of the ES functioning within the framework of the general ES. Special attention is paid to the description of the knowledge and datum surface, to the algorithms of direct and reverse illegible logical data output in taking decisions as to defects of the patient's prosthesis in accordance with the signs observable. The work of the ES is demonstrated with special reference to concrete cases. Analysis is made of the estimates of the sensitivity to the initial data. The ES presents knowledge in depth, being designed in two versions: for practical (individual and mass) prosthetics and training purposes.

[An expert system for choosing prostheses for the lower extremities (hip) and assessing the quality of the prosthesis. I].

The authors describe the structure, characteristic features and experience gained with the employment of an expert system for the choice of hip prostheses (in cases of unilateral amputation) and assessment of the prosthetics quality. Word the requirements for hardware and software, present functional subsystems corresponding to certain interrelated stages of prosthetics. A variant has been devised of an appropriate training expert system with a profound representation of intelligence in an object area.

[Computer software and hardware requirements for the differential diagnosis of periodontal diseases using discriminant analysis].

A method of differential diagnosis of parodontium diseases has been devised with the aid of a functional diagnostic system using multichannel rheo- and photoplethysmographs and the deciding rule of discriminant function computation in accordance with an algorithm elaborated. As many as 200 patients have undergone diagnostic examination with the aid of the above-indicated software and hardware system to demonstrate a high probability (92%) of diagnosis.

[The use of discriminant analysis for the differential diagnosis of periodontal diseases].

Basing on rheo- and photoplethysmography combined with mathematical methods and computers the authors have developed a method for the differential diagnosis of periodontal diseases (gingivitis, periodontitis). Diagnostic studies carried out in 200 patients have shown a high probability (at least 92 percent) of the method for the differential diagnosis of periodontal diseases.

[A personal system of automated planning of microprocessor printing plates for radio-electronic medical equipment].

Personal CAD/CAM for graphic projection and manufacture of microprocessor PCB masks, input information-carrying medium and numeric controlled lathes has been designed. CAD/CAM instrument-software could be interfaced to an APRICOT type PC and to the USSR-manufactured equipment. Personal CAD/CAM is considered as a person-machine system and works in the automatic and semi-automatic modes. The convertor program, which is included into the software allows one to use the present CAD/CAM system with the alternative USSR and foreign manufactured systems.

[An expert system for therapeutic and diagnostic processes].

Specific peculiarities of the basic knowledge examination system are described herein. They allow to design a consulting system for the intensive care specialist. This system works out recommendations on the artificial kidney applications and recommends dialysate contents for individual applications. Specific examples of the examination medical system LEDI-Z are demonstrated.

[A system of diagnostic tests, the providing of medical equipment and the level of automation in ambulatory care clinics].

Some problems of establishing the complex of diagnostic investigations based on the use of medical instrumentation in outpatient clinics with 50 000 and more population being served are discussed. The methodology to evaluate informative signs according to every diagnostic examination is presented. Computational relationships for quantitative evaluation of informative signs are given as well as an algorithm of generalized examination results reporting.

[Automation of the technological medical process in ambulatory polyclinic and hospital establishments].

Now, the creation of automated instruments, apparatus and systems providing complex instrumentation of medical technological processes in ambulant-polyclinical and hospital centers became the main line of the medical technique's development. Primary problems and objects of automation are determined from the proposed models of managing the treatment and diagnostic processes in these establishments.

[Construction of a system for the automatic design of printed-circuit boards for medical electronic apparatus].

The structure of the system for designing printed circuit boards based on such widely used technical equipment as minicomputers and unified-system computers, is discussed. The system allows one to carry out, in consecutive stages, the automation of the process of designing printed circuit boards and the technological provision for their manufacture. The principles of designing the boards on the basis of algorithms using the notion of channels and including the subdivision of the total circuit into separate structural units, the location of different elements in these units and their tracing are described in detail. The stage of making up the design documents and the control punch tapes containing the final stage of tracing correction with the output of the control data or a coordinatograph and numerically controlled machines is considered.
