Evaluating the Cardiac Engine

摘要

The present invention relates to computer-based methods for evaluating an individual's cardiovascular system and computer systems for use in such methods. The computer system recognizes a portion of the individual's cardiovascular system though an imaging device input, then assesses the cardiac power, energy and efficiency during the cardiac cycle. The computer system evaluates circulatory motion and properties of circulatory fluid, and further optimizes the cardiovascular analysis through suggested repositioning of the imaging device.

主权项

1. A computer system for evaluating an individual's cardiovascular system, the system comprising:
a recognition module configured to recognize a portion of an individual's cardiovascular system; a geometry module coupled to the recognition module and configured to assess a dimensional geometry, physiology, or a combination thereof of the recognized portion of the individual's cardiovascular system at a cardiac cycle time t; an interval selection module configured to select a cardiac cycle interval as a function of cardiac cycle time t; an interval evaluation module responsive to the geometry module's assessment of the recognized portion of the individual's cardiovascular system and configured to compute current, cardiac power, cardiac energy, cardiac efficiency, or a combination thereof of the individual's cardiovascular system at the selected cardiac cycle interval, cardiac cycle time t, or a combination thereof, wherein the interval evaluation module indicates an evaluation of cardiac energy and cardiac efficiency; a flux state module configured to evaluate inductive flux state λ of the individual's cardiovascular system at the cardiac cycle time t; and a magnetic permeability module configured to compute magnetic permeability at the cardiac cycle time t; wherein the inductive λ and μ are used to refine computation of current, cardiac power, cardiac energy, cardiac efficiency, or a combination thereof.
