We realized a new electrical impedance tomography (EIT) based on the tetrapolar circuit method with the scanning of magnetic field superimposed for localizing the current distribution in biological tissues. In this method, two voltage differences are detected on two sides of the body, in which the distribution of constant current component is parallel. As the voltage difference of one side becomes zero, the eddy current component is produced by a magnetic field applied to the body from an electromagnetic core. Sustaining this state, the electromagnetic core is moved from side to side. The voltage differences at the other side measured during this movement of the magnetic field are used to estimate the resistance distribution of one dimension. As the result of a model experiment, it was confirmed that this method would be useful to realize EIT.

Einthovenの心電計の発明によって心臓病の診断は大きな進歩をとげた。一方, この十年余ペースメーカーの出現によって房室ブロックをはじめとする不整脈の治療は大きな変革をとげ, エレクトロニクスは心臓病の診断と治療の両面に非常に大きな役割を果たすに至った。1976年東京において第5回国際ペースメーカーシンポジウムが開催されにことになり, わが国においても一般の関心が高まると考えられるが, ここでは房室ブロックおよびペースメーカーについて過去から現在までの概説を試みる。

Various vital sensors have been developed for patient monitoring. These sensors restrict patients physically or mentally since either electrodes or probes must be mounted onto a patient's body and then connected to a measuring instrument using a lead wire. In this study, a biomedical-signal detection system capable of being used without subject awareness on the basis of terrestrial magnetism was developed for home use and remote care. When a subject lies on a bed mattress that is situated on a magnetic sheet, the system detects the change in magnetic field related to respiration and heart beat. We have also developed an on-line system that can separate respiration and heart beat components from the detected signal.

Visually induced motion sickness is one of the detrimental effects of video images on human psychosomatic state. Several studies for alleviating this effect have been cumulated in recent years. One of the studies reported that people with high heart rate tended to be immune to the motion sickness. This fact motivated us to assume that the increase of subjects' heart rate through physical exercise before video watching could prevent them from the motion sickness. Then we investigated the effects of video exposure with such pre-exercise on the motion sickness. First we recorded psychosomatic state of 23 volunteers using the simulator sickness questionnaire (SSQ) before and after watching extremely unpleasant video images of a mountain-bike ride capable of visually inducing motion sickness. Then we classified them into nausea and non-nausea groups, based on SSQ evaluation. Subjects' heart rate in nausea group increased gradually during video exposure, while that in non-nausea group was nearly constant. By imposing a 5-minute pre-exercise on 12 subjects in nausea group before video exposure, 10 subjects became immune to the motion sickness, demonstrating that the pre-exercise would be efficient for alleviating the motion sickness. In addition subjects' heart rate in nausea group remained at a higher level during video exposure than at rest, whereas it returned to the rest level immediately after the pre-excise without video exposure.

The aim of this research was to assess the physiological signals which were relevant working efficiency under mental workload. Eleven healthy subjects were examined. In the first step, their mood status and stress level were evaluated with questionnaire methods:“Profile of Mood States (POMS)” and “Stress Self Rating Scale (SSRS)”, respectively. In the second step, electroencephalography (EEG) and photoplethysmography under the mental workload tasks in four auditory stimuli (silent circumstance, white noise, classical music, and up-tempo music) were measured. The mental workload tasks consisted of two parts:performing Uchida-Kraepelin test (calculating task:CAL) on PC monitor in two minutes and fixating on a crosshair image (after CAL) in two minutes. A procedure of the mental workload task in each auditory stimulus was repeated three times. EEG data were analyzed using a discrete Fourier transform to obtain power spectral density (PSD) in theta, alpha, and beta bands. Pulse waves from photoplethysmography were analyzed for estimating the pulse wave amplitude (PWA) and length (PWL). PSDs of theta band in silent circumstance and classical music under and after CALs, alpha band in classical music under and after CALs, and beta band in up-tempo music under CAL on most or all areas were significantly larger than those in the other auditory stimuli. The results of photoplethysmography analysis showed that changes of PWA and PWL in silent circumstance and classical music were more stable than those in the other auditory stimuli. It was suggested that the classical music would not only affect brain activity under the mental workload and augment the efficiency of it, but also facilitate recovery of the physiological conditions from the stressful situations. These events from the physiological point of view showed that working environments could be considered to avoid adding stress on the brain function and autonomic nervous system during and even after the tasks.

<p>Since ultrasonography has insufficient performance in depicting the vertebral surface, most examiners perform epidural anesthesia using landmarks on the back without ultrasonography. The final purpose of this study is to improve the performance by ultrasonography in depicting thoracic vertebral surface.RPM method is one of the bi-static imaging methods, it estimates the reflection point on a target surface by intersections of plural ellipses, where the focal points of an ellipse are the position of a transmit element and that of a receive element.We investigated the performance of the RPM method in an experimental study using a phantom with a concave surface of a 2 cm curvature radius. The depicted region of concave surface acquired using the conventional method and the RPM method was approximately 14.8% and 17.7% of the whole concave surface, respectively. This result indicates that the RPM method has high performance in depicting sloping target boundary.</p>

The aim of this study was to clarify the mechanical action of the infant tongue during sucking. Therefore we developed an artificial nipple that contained multiple small built-in force sensors which was capable of measuring tongue-artificial nipple contact pressure in real-time. A force sensor was a cantilever structure composed of a thin stainless steel beam and all-purpose foil strain gauges attached to the surface of the beam. The signals obtained from the force sensor were amplified, and were transferred to a PC via a USB port. Using this system, measurements were taken in three infants. The output waveform was observed in all subjects, and the rate of sucking was about two times per second. In addition, the pressure waveform indicated peristalsis-like movement of tongue in infants with established oral feeding. This system can quantitatively measure individual differences in tongue movement.
