    Recent developments in the field of computerized clinical electroencephalography (EEG) are surveyed, with particular reference to techniques of analysis of background (stationary) EEG activity, transient (nonstationary) activity, and to integrated systems for multichannel clinical EEG's. A variety of approaches have been used for the basic EEG analyses. For background activity, the fast Fourier tr... View full abstract»

    To study the role of internal geometry and inhomogeneities in the "forward problem" of electrocardiography (ECG), a mathematical model was constructed which permitted manipulation of these variables. The model, which consists of two eccentric systems of concentric spheres, contains all the important torso compartments, namely the blood cavity, the myocardium, the pericardium, the lung region, the ...

  • Electromagnetic Absorption in a Multilayered Model of Man

    A multilayered planar model is used to examine the dependence of whole-body power absorption on the configuration of surface layers, e.g., skin, fat, and muscle which normally occur in biological bodies. It is found that the layering resonance for three-dimensional bodies (as opposed to the geometrical resonance) can be predicted quite accurately by a planar model. Calculations for a multilayered ...

    A comparative study has been made on the surface and serosal data recorded from the human stomach. Autoregressive technique has been used for frequency analyses. It is observed that slow waves in both the surface and the serosal data can be detected with reasonable success using a moderate model order. An examination of the frequency spectra reveals that while the serosal signals have a well-defin... View full abstract»

    A new scheme is proposed for the detection of premature ventricular beats, which is a vital function in rhythm monitoring of cardiac patients. A transformation based on the first difference of the digitized electrocardiogram (ECG) signal is developed for the detection and delineation of QRS complexes. The method for classifying the abnormal complexes from the normal ones is based on the concepts o... View full abstract»

    Development of a miniaturized fiberoptic/dye probe is described for intended application with a neonatal 5 French (FR) umbilical artery catheter (UAC). A simplified model of the optical system leads to the choice of 5 mil plastic fibers for which a large numerical aperture compensates for high absorption losses at 930 nm over short distances. Initial dog trials have yielded excellent in situ oxime... View full abstract»

    This paper presents an approach to the problem of estimating the number of exponential functions and the pertinent parameters in the output of a radioactive tracer kinetic process. In particular, application of a criterion called an information theoretical criterion (AIC) for the estimation of the number of exponential functions is proposed; AIC was introduced by Akaike for the estimation of the o...

    Erythrocytes heated by either microwave irradiation or conventional techniques were examined for loss of hemoglobin (Hb) and potassium (K+). In all experiments, microwave heated red blood cells (RBC's) were directly compared with RBC's warmed to the same temperature by use of an adjustable incubator and with RBC's maintained at room temperature. Microwave irradiation was carried out at either 2.45... View full abstract»

    Present cardiac pacemaker designs use either unipolar or bipolar electrode systems. Advantages of unipolar electrodes for stimulation are listed; then arguments in favor of bipolar electrodes for sensing are cited. A proposed system combines unipolar stimulation with bipolar sensing and may be implemented by adding a differential-input stage to the sensing amplifier. View full abstract»
