[Microprocessor controllers in portable ultrasonic diagnostic units].

Application possibilities of the unified microprocessor module, which allows one to widen ultrasound diagnostic unit's parameters, have been considered herein: i.e. maintenance of the unit's functional keyboard, output of the alphabet-digital information, cursor, markers on the monitor screens, monitoring of the movement of markers and cursor all around the screen, calculation of the distance between them, monitoring of the unit's modes, calculations of the table data based parameters and established formulas. The tasks fulfilled by the microprocessor module could be fulfilled when more up-to-date ultrasound units are designed.

[Use of microprocessor controllers for the analysis of Doppler signals of blood flow velocity].

Herein the approach to the design of the ultrasound Doppler constant emitters has been considered. One of its versions is the described unit, which allows one to store in its memory and display on the TV monitor curves of the blood flow being divided according the direction, to carry out the spectrum analysis of the Doppler signal in the chosen time intervals, to calculate the quantitative parameters of the blood flow.

[Automated ultrasonic diagnostic systems for outpatient clinics].

Some ways to improve informative capacity of ultrasonic diagnostic examinations are discussed, and their application in an extended network of outpatient clinics by using the state-of-the-art automated devices, microcomputers and microprocessors in particular, are considered. Possible approaches to automating ultrasonic diagnostic examinations are analysed, and requirements for hardware and software of ultrasonic complexes are specified. A configuration structure of complexes for processing monodimensional and bidimensional echo signals is presented.

[New methods of information technology for designing ultrasound diagnostic devices].

The paper outlines the problems in the analysis of basic trends in the development of current ultrasonic scanners. It shows that at present the architecture of ultrasonic signal-visualizing devices is being modified due to the wide introduction of progress in the technology of multi-media and to the development of specialized transducers designed for studying certain organs and regions of the human body.

[Instrumental and programmed support for integration of diagnostic information within the local network].

The paper deals with the problems in the integration of diagnostic information obtained by various devices, suggests that this process should be implemented by local networks, considers the basic tasks arising with this approach, and gives how to solve some of them. It is shown that this approach can be applied when two basic subdivisions of a health institution: therapeutical and diagnostical--interact.

[The design of a family of ultrasonic diagnostic units based on up-to-date computer technologies].

Small ultrasonic devices are now being used in medical practice. However, the vast majority of them represent designingly completed systems which cannot include additional soft- and hardwares to accumulate measurements and to set up databases, to make additional postprocessing, to transmit measurements along networks and telephone lines, etc. On the other hand, in our and foreign countries, work is under way in designing the systems of archiving and treating ultrasonic images, working places for a physician engaged in radiation diagnosis. But at the same time direct joining of ultrasonic equipment with standard computer facilities is impossible in many practical cases. To design ultrasonic devices by using Multimedia IBM PC technology which may integrate various informational media, such as display, sonic information, and textual data is one of the ways of solving this problem. With this, the hardwares of ultrasonic devices are realized in the construction of standard IBM PC modules. Sonomed ultrasonic devices may be considered to be alternatives of Multimedia IBM PC-based devices.
