[Computer system of electronystagmographic examination. Part I. Measuring equipment and algorithm of ENG test].

The work presents the computer system created by the author for automatic registration and analysing oculomotor response records evoked by the stimulation of the vestibular organ. The basis elements of the system had been described. It consists of microcomputer IBM PC/XT/AT, measurement and stimulatory apparatus, multimodular controlling and analytical software as well as the algorithm of system management.

Choosing the right computer system.

We are living in a world where virtually any information you desire can be acquired in a matter of moments with the click of a mouse. The computer is a ubiquitous fixture in elementary schools, universities, small companies, large companies, and homes. Many dental offices have incorporated computers as an integral part of their management systems. However, the role of the computer is expanding in the dental office as new hardware and software advancements emerge. The growing popularity of digital radiography and photography is making the possibility of a completely digital patient record more desirable. The trend for expanding the role of dental office computer systems is reflected in the increased number of companies that offer computer packages. The purchase of one of these new systems represents a significant commitment on the part of the dentist and staff. Not only do the systems have a substantial price tag, but they require a great deal of time and effort to become fully integrated into the daily office routine. To help the reader gain some clarity on the blur of new hardware and software available, I have enlisted the help of three recognized authorities on the subject of office organization and computer systems. This article is not intended to provide a ranking of features and shortcomings of specific products that are available, but rather to present a process by which the reader might be able to make better choices when selecting or upgrading a computer system.

A modular computer system for the nuclear medicine/ultrasound laboratory.

Computer-controlled graphic displays are a necessity in many nuclear medicine studies. The authors propose using a set-up consisting of three modules: (a) a display system based on television technology; (b) an instrument interface employing list mode and having a low information loss rate; and (c) flexible modular software which can easily be tailored to the needs of both radiologists and technicians. The authors consider a mini-computer system with broad, flexible applications to be a valuable tool, particularly for those function studies which can only be done by means of nuclear medicine techniques.

[A personal computer system providing various graphs of mortality rates].

PURPOSE: We devised observational methods for showing relations of mortality rates to age and period in various ways. And we contrived a personal computer system to realize the methods. The purpose of this report is to evaluate the methods and the system. METHODS AND MATERIALS: We contrived the system which provides some graphs useful for observing age-period-specific mortality rates. The program was written in Visual Basic on a Windows personal computer. The graphs provided by the system are bird's-eye view, contour map and mortality curves. The system is also made to present any graph desired for any specific required time. A smoothing method is also provided with the system to diminish random error, therefore the characteristics of mortality can be grasped easily. The system was applied to the mortality rates of malignant tumor for the last 45 years (1950-1994) in Japan. RESULTS AND CONCLUSION: Examples which show that one could easily observe the trend and structure of mortality rates by using the method were presented. Because the system can present any of the graphs instantly, so we can observe mortality step-by-step; we can seen the mortality graphs as a whole from a bird's eye view, then observe it in detail by a contour map graph, and furthermore look into the point of interest by mortality curves. Thus, the system will be useful to observe mortality rates.

A hybrid computer system for use in cardiology.

Recent upsurge in the use of physiologic data for medical diagnostic and treatment procedures has prompted the medical profession to use the computer to automate and reduce the time required for data processing. Although the digital computer has traditionally been used to perform these tasks, a hybrid computer (combined analog and digital) has been found to provide many advantages over the digital computer, especially where on-line data processing is concerned. As a result, the Bio-Medical Engineering Center has installed a centrally located hybrid computer system at Ohio State University. One of the applications of this system has been processing cardiac catheterization data. Data is transmitted between the hospital and computer via infrared optics. The data can be analyzed in real time, with the results immediately available to the physician.

A method for measuring specific activities of 14C-labelled compounds by gas chromatography-mass spectrometry-computer system.

A method for measuring specific activities of 14C-labelled compounds by gas chromatography-mass spectrometry-computer system (GC-MS-CPU) was developed. This method was proved to provide practically precise and accurate specific activities of various 14C-labelled compounds with such merits as requirement of small amount of samples, being applicable to volatile compounds, and convenience. The C.V. percent obtained for tested compounds was within 3.9 and the reliable sensitivity should be over 37 MBq/mM (1 mCi/mM). This method was also useful for obtaining information on the labelling pattern and the synthetic procedures applied.

A computer system for biomedical equipment maintenance reporting.

Biomedical equipment maintenance and repair activities involve an increasing amount of paperwork and report generation. A computer system is described that collects the necessary data on-line for accuracy and efficiency. The system can generate various reports relating to repair history, spare parts usage and preventive maintenance scheduling. It is implemented on a time-sharing minicomputer, and can reduce substantially the time spent by biomedical engineers in documenting their activities.
