  • Non-invasive method and apparatus for describing the electrical activity of the surface of an interior organ
    Patent number: 4961428
    Abstract: A method and apparatus for processing a plurality of signals provided by an array of electrodes disposed on the surface of the body further comprising a reconstruction of the electrical activity on the surface of a selected interior organ according to the plurality of array signals and a selected model of the body in the region of the interior organ and the electrode array. The reconstruction includes assumptions made according to a priori knowledge of the selected model and permits reconstruction of the electrical activity on the surface of the interior organ and can further provide practical solutions with underdetermined sets of equations. The present inventions further includes reconstruction including a power spectrum analysis of the array signals to permit detection and localizing of a predetermined physiological condition. The power spectrum analysis may further include a frequency domain analysis according to the minimum relative entropy of the measured signals.
