摘要:

Use of a development system can reduce the time and cost of developing microprocessor systems. The requirements and operation of a development system is described and the paper considers the use of kit computers as the basis of low cost specialist development systems providing an example of the selection of a kit to suit individual needs.

摘要:

The authors describe the processing of electro-encephalograms (EEG's) by means of a mini computer in the clinical neurophysiological department of a district hospital. The new way of processing not only creates the possibility of digital filing of EEG signals, but also allows new methods of presentation and quantification of EEG's. Thus, for example, cerebral deviations can be made visible in the electrical brain signal, when they are not perceptible to the naked eye.

摘要:

The development of diagnostic applications of ultrasound has tended to follow the evolution of electronic technology, and while this development has resulted in benefit to the patient, the relatively unsophisticated scientific ideas have been adequate. The present paper reviews briefly some elements of the development of diagnostic imaging in relation to their scientific bases. The discussion is particularly concerned with the popular grey-scale pulse-echo systems and the philosophy behind future developments that may lead to the successful pursuance of tissue differentiation, and the optimisation of instrumentation. Of necessity, the discussion touches the more fundamental areas of measurement of the ultrasonic parameters of tissues, the development of tissue models, the measurement of transducer field characteristics, the studies in visual perception; and is briefly linked to biological effects and therapy.

摘要:

A good method of assisting the right ventricle of the heart has, up to the present, not been available. This paper presents a new approach to assisting the right ventricle of the heart which can be utilised independently or during cardiac surgery. Through implementation of this approach, and timed inflation and deflation of several types of balloon catheters in the pulmonary artery, distal pulmonary arterial flow is augmented with subsequent unloading of the right side of the heart. This approach, hopefully, will be of benefit in the treatment of atherosclerotic and congenital heart disease as well as in many cases of pulmonary hypertension.

摘要:

The use of aerosol sprays in the treatment of respiratory tract disorders is limited by the size of droplet that can be produced; smaller particles are able to travel further down the tract. A system is described for producing small droplets (<4µm) of controlled size by modification of a commercially available nebuliser.

摘要:

The International Conference on Rehabilitation Engineering held in Toronto in June last year was the first annual conference of the recently formed Rehabilitation Engineering Society of North America. This report by Nigel Ring discusses some of the topics raised at the conference and compares the North American approach to rehabilitation engineering with that in the UK.
