    The application of engineering tools to life science problems has both generated the incentive and provided the means for quantitative measurement of physiological variables. This trend is clearly demonstrated in the development of instrumentation to quantify human sexual response. Current devices to measure this response in males and females have evolved through several device generations and ref... View full abstract»

    Using a one-dimensional model of wave propagation, the ultrasonic attenuation can be estimimated from spectral analysis of RF A-scans. The results of computer modeling studies and measurements on tissue equivalent phantoms indicate that spectral analysis methods are accurate only in the regime where a one-dimensional model is adequate. In the near field of a typical B-scan transducer, a one-dimeni... View full abstract»

  • A Comparison of Two Quantitative Approaches for Correction of Background Counts of First-Pass Left Ventricular Time-Activity Curves: A Numerical Investigation

    Publication Year: 1983 , Page(s): 326 - 332
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (4863 KB)  

    This report describes two quantitative approaches for correction of background counts for the determination of the left ventlicular ejection fraction from first-pass radionucide angiocardiography: one is based on the technique of complex demodulation and the other is based on the technique of spline interpolation. The least squares method is used as a paraneter estimation procedure. A piece-wise l... View full abstract»

  • Adaptive Real-Time Wavelet Detection

    Detection of wavelets in noisy signals is important for many biomedical as well as other applications. An adaptive wavelet detection system is described, based on the cross correlation method. The method is restricted to fnite-length, nonoverlapping wavelets. A random reference correlator (RRC) circuit is used to estimate the correlation between signal and template, eliminating the need for expens... View full abstract»

  • A Magnetically Coupled Multimicroelectrode System

    A multimicroelectrode system is described in which the microelectrodes are individually magnetized and coupled to one another by the magnetic force acting on each microelectrode. This arrangement increases the mechanical strength of the fine microelectrodes, and also restricts the bending of each microelectrode wire. This Multimicroelectrode structure allows independent and parallel penetration of... View full abstract»

  • Effects of ELF Electric Fields on the Isolated Frog Heart

    Isolated hearts of Rana pipiens were exposed to ELF electric fields. Above threshold values of 20-30 V/m, the fields caused the heart rates to increase. Frequencies of applied fields near the natural rate of the heart (approximately 0.5 Hz) were more effective than higher frequencies. View full abstract»

    Pulse spectral graphs (PSG) were obtained from pulses taken on the wrist by using electronics and computers. Energy ratio (ER) is defined as the ratio of the energy of PSG below 10 Hz to that above 10 Hz. We find that the ER for healthy persons is above 100 at all three-finger positions on both wrists, but those for sick persons are below 100 at some specific positions of pulse-taking. The specifi...

  • Signal Distortion in the Electrocardiogram Due to Inadequate Phase Response

    Electrocardiographic monitoring is used for arrhythmia analysis and for the detection of myocardial pathology, especially ischaemia and infarction, when waveform distortion must be minimized if reliable results are to be obtained. ST segment distortion has been noted to occur with ambulatory recorders and some electrocardiographs. View full abstract»

  • Prosthesis Control Using a Nearest Neighbor Electromyographic Pattern Classifier

    An investigation was conducted into the feasibility of applying a nearest neighbor algorithm to the problem of recognizing electromyographic (EMG) signal patterns for prosthesis control. A nearest neighbor algorithm correctly identified arm motions as belonging to one of six pattern classes from 72 to 100 percent of the time. A condensed nearest neighbor classifier was constructed to determine wha... View full abstract»

  • Dispersion of the Somatosensory Evoked Potential (SEP) in Multiple Sclerosis

    A fast Fourier transform technique was used to quantitate the dispersion of the somatosensory evoked potential elicited by median nerve stimulation. The evaluation was proportional to the log of the SEP spectral energy between 380 and 1000 Hz. This was linearly scaled to a range of numbers between zero and five representing minimal mal to severe degrees of dispersion, respectively. In 21 controls,... View full abstract»

    Transventricular impedance during fibrillation was measured with two methods: 1) by injecting a low constant sinusoidal current (obtaining a Z value), and 2) by using the time constant of an exponential defibrillatory discharge (giving an R value). One group of eight dols (Group 300) was normothermic and another group of 14 dogs (Group 400) was hypothermic. The left anterior descending coronary ar... View full abstract»
