  • Determining blood flow by measurement of temperature
    Patent number: 5860922
    Abstract: A method for determining a flow rate of a substance or a thermo-contrast agent in an object including a surface and an upstream region, and the method comprising the steps of (a) providing the upstream region with a thermo-contrast agent; (b) obtaining successive temperature readings of at least a part of the surface of the object; (c) generating a temperature response curve from the temperature readings; (d) extracting a parameter from the temperature response curve; and (e) determining the flow rate from the parameter.
    Type: Grant

  • Determining coronary blood flow by cardiac thermography in open chest conditions
    Patent number: 5692510
    Abstract: Methods for determining the flow rate of a substance within an object by extracting and mathematically manipulating numerical parameters from a thermoimaging temperature response curve of the surface of the object. The methods of the present invention are suitable to determine coronary arteries flow rates and myocardial perfusion rates in open chest conditions.

  • Method of displaying coronary function
    Patent number: 5151856
    Abstract: A method of displaying cardiac function which forms by helical or segmental analysis a three-dimensional cage model which can be shaded and color coded to indicate local and regional dysfunction by thickening or motion and stresses. On this model is superimposed the coronary artery tree including stenosed segments as obtained from the same patient by angiograms and the resulting three-dimensional coronary and mechanical model can be subjected to animation and analysis for diagnostic purposes and to simulate effects of treatment.
