    This paper presents preliminary results obtained from a mathematical model of intracardiac electric field plethysmography. This method is based on measurement of the electrical field inside the heart with excitation applied laterally to both sides of the thorax. Two models have been examined. The first one was the spherical shell embedded in conductive medium. The second one has been constructed u... View full abstract»

    The authors derive expressions for the dependence of propagation speed on wavefront curvature directly from the excitation rules for a discrete model of an excitable medium in the limiting case of no recovery. This allows the authors to find the plane wave speed, critical curvature, and effective diffusion constant of the medium. Reproduction of these features is essential for modeling reentrant a...

  • Magnetic field measurements of gastrointestinal activity

    Publication Year: 1996, Page(s):1919 - 1920 vol.5
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (196 KB)

    Motility is the electro-mechanical processes by which gastrointestinal (GI) muscle is stimulated to contract, resulting in propulsion of contents. Assessment of motility must involve evaluation of GI smooth muscle electrical activity. In this study, the magnetic field corresponding to electrical activity was measured over the abdominal region using a 37 channel SQUID gradiometer system. Three fema... View full abstract»

    Within the world-wide community of medical thermographers there is general agreement that standardisation in a number of aspects of thermography is both desirable and necessary if meaningful comparison of results between centres is to be achieved. This paper outlines the proposals for a draft Standard for medical thermography that will cover aspects of thermographic terminology, technique and appl... View full abstract»

    Electrogastrography (EGG), the cutaneous recording of the myoelectrical activity of the stomach using surface electrodes, is attractive due to its noninvasiveness. Despite many attempts made over the decades, analysis of surface EGG has not led to identification of contraction-related electrical response activity of the stomach that would help the clinician to diagnose motility disorders of the st...

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (248 KB)

    Motion curves are commonly used for evaluating gait performance during walking. Nevertheless, one of the biggest problems for both students and clinic personnel is to correlate information extracted from motion curves to postural development of body segments during walking. Without doubt, this latter fact complicates the analysis. This article describes a technique that is capable of recreating hu... View full abstract»

  • The effects of pulse rate, artefact and pulse strength on oscillometric non-invasive blood pressure measurements

    Publication Year: 1996, Page(s):1977 - 1978 vol.5
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (188 KB)

    The authors examined the effects of pulse rate, pulse strength, and artefact on 20 adult oscillometric noninvasive blood pressure measurements using NIBP test simulators. Over a range of pulse rates from 40 to 200 bpm the 20 NIBP monitors studied recorded little change in registered pressures. The monitors achieved consistent readings at low pulse rates by decreasing the deflation rate and hence i... View full abstract»

    A detailed two-dimensional (2-D) finite element model (FEM) of the electroconductive anatomy of a human thorax was formulated to investigate the fields and currents generated by the on-set of a magnetic field. The 2-D model of the thorax was constructed from archived cross-sectional maps and accounts for eight isotropic tissue conductivities and the anisotropic conductivity of the intercostal musc...

Hence this tool is used to test the theoretically proposed constitutive relations that describe the mechanoelastic properties of the RBC. Consequently, it opens the way for finding the optimum constitutive re... View full abstract»

    To visualize the subendocardial arteriolar blood velocity, the authors developed a high-speed CCD microscope. The vascular images focused on the special CCD through a needle-probe were stored on a digital memory every 5 ms (200 images/s). The size of the visual field is 1×0.8 mm2, and the spatial resolution is less than 4 μm. The blood flow velocities in the microvessels were v... View full abstract»

    For optimizing medical applications, it is important to understand how, and to what extent, the electromagnetic field propagates inside a living-tissue configuration. Therefore, the electromagnetic field excited by a current pulse in a circular loop has been calculated for a model of plane-stratified biological tissues. To incorporate the effects of dispersion in the configuration, permittivity mo... View full abstract»
