    This abbreviated history of COMAR is presented not only for the interest of the reader but to communicate to a new generation of participants and supporters of COMAR today's challenges—which, in fact, are deeply rooted in the history of COMAR and continue with no end in sight. Not all highlights will be described in depth and only the most important over-arching issues are singled out for t... View full abstract»

    The authors show the mechanism of high frequency attenuation introduced by signal averaging and how it can be avoided by applying a high resolution alignment approach, coupled with optimal filtering of the reference lead. Several authors suggest that ventricular late potentials are due to high frequency components caused by abnormal ventricular conduction. To investigate properly this hypothesis, ...

    The increase of age-related diseases such as musculoskeletal and neurological dysfunction will require increased use of rehabilitation therapy. The effectiveness of this treatment depends of the skill of the therapist and the functionality inherent in the therapeutic device used. Here, a new EMG biofeedback controlled therapeutic traction machine was developed to relieve neck pain or cervical comp... View full abstract»

  • Using the algebraic sum method in medical expert systems

    Publication Year: 1996, Page(s):80 - 82
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (588 KB)

    In the development of a medical expert system, the choice of algorithms is an important consideration. According to 1979 statistics, some 60% of medical expert systems were based on the Bayes method, 30% were based on a linear discriminant function, matching handle and criterion tree, and 10% were based on other algorithms. Overall diagnostic accuracy rates were generally about 90%. Although the B... View full abstract»

  • Applying Bayes' theorem in medical expert systems

    Publication Year: 1996, Page(s):76 - 79
    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (732 KB)

    The authors think that the main problem with the application of Bayes' theorem in medical expert systems is that the formula itself cannot resolve the contradiction between frequency of disease manifestation and its specificity, especially for those manifestations that have a very low frequency but a high specificity. The authors have found in practice that the weighted summation method in its var... View full abstract»

    Cited by:  Papers (25)  |  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1024 KB)

    An overview of the electrodermal screening test is given. An existing model of the electrical properties of the skin has been the accepted scientific standard for decades. But this model is based entirely on mechanistic principles and it fails to explain many biological phenomena, particularly those relating to acupuncture points and meridians. The author has developed a new model which, unlike th... View full abstract»

    This study focuses on improving microcalcification classification by establishing an efficient computer-aided diagnosis system that extracts Daubechies-4 and biorthogonal wavelet features. These wavelets were chosen because they have been used in military target recognition and fingerprint recognition research with images characterized by low contrast, similar to mammography. Feature selection tec... View full abstract»

    Both traditional meridian theory and modern applications such as the electrodermal screening test (EDST) demonstrate an essential link between bioinformation and meridian phenomena. From the theoretical and clinical work thus far performed by many researchers, it is clear that meridians and bioinformation are essential elements of the functioning of the human body. There are many possible clinical... View full abstract»

  • A thresholding method for blood-aggregate images

    Among the wide ranging forms of medical diagnostic modalities, blood analysis is one of the most common, and is likely to become more important as various blood related diseases become more pervasive. Histogram-based methods are among the most popular for thresholding a biomedical image of blood aggregates in a plastic tube. However, these methods often do not provide good results over the entire ... View full abstract»

    The organ-meridian relationship is investigated. The acupuncture and meridian system of traditional Chinese medicine is an important, real biophysical aspect of the living body. With the electrodermal screening device (EDSD), it is possible to define, both quantitatively and qualitatively, much of the meridian system. The meridian system is essential to most or possibly all bodily functions. The E... View full abstract»

  • Modeling and canceling tremor in human-machine interfaces

    Publication Year: 1996, Page(s):29 - 36

    Zero-phase modeling and canceling of tremor can improve precision in human-machine control applications. Past methods of tremor suppression have been hindered by feedback delays due to phase lag and by the inability to track tremor frequency over time. The weighted-frequency Fourier linear combiner (WFLC) is an adaptive noise canceller that precisely models tremor with zero phase lag. This article... View full abstract»

    Sources of RF radiation in the human environment continue to proliferate. New applications of RF energy in telecommunications are being developed at an astonishing rate. As for other RF-emitting devices, concerns have been raised as to the safety of cellular telephones. Cellular telephone base station emissions have been measured and found to be below exposure standards developed by the NCRP and t... View full abstract»

    There are two predominant types of noise that contaminate the electrocardiogram (EGG) acquired during a stress test: the baseline wander noise (BW) and electrode motion artifact, and electromyogram-induced noise (EMG). BW noise is at a lower frequency, caused by respiration and motion of the subject or the leads. The frequency components of BW noise are usually below 0.5 Hz, and extend into the fr...

    Discusses measuring local activation direction variability using short segment lengths to quickly differentiate fibrillation from regular rhythms. It is concluded that the spatial precision of local activation direction shows promise as a potential discriminator of atrial fibrillation from regular atrial rhythms. For the authors' study set, excellent discrimination of atrial fibrillation from regu... View full abstract»

    Acupuncture has been used for thousands of years and is effective in a wide range of situations. It has not been integrated into modern health care primarily because of lingering suspicions that it is not scientific. A bioenergetic model has been developed to explain nearly all aspects of acupuncture and meridian theory, but there remains a definite prejudice against human energetic theories in th...
