  • Patent number: 5266035
    Abstract: The present invention is a material and method of making the material that exhibits improved radiation attenuation simulation of real lungs, i.e., an "authentic lung tissue" or ALT phantom.Specifically, the ALT phantom is a two-part polyurethane medium density foam mixed with calcium carbonate, potassium carbonate if needed for K-40 background, lanthanum nitrate, acetone, and a nitrate or chloride form of a radionuclide. This formulation is found to closely match chemical composition and linear attenuation of real lungs.The ALT phantom material is made according to established procedures but without adding foaming agents or preparing thixotropic concentrate and with a modification for ensuring uniformity of density of the ALT phantom that is necessary for accurate simulation. The modification is that the polyurethane chemicals are mixed at a low temperature prior to pouring the polyurethane mixture into the mold.

  • Patent number: 4639223
    Abstract: In a heart display system a computer is operable to simulate different selected hearts, each with a different pattern of electrophysiological pathways, which conduct waves of depolarization. The computer determines the conduction in the pattern of pathways of a selected heart in accordance with selected parameters and inputs provided by the operator. In simulating the heart, the computer determines whether a depolarization wave proceeds from one pathway segment to an adjacent segment by examining whether the adjacent segment is polarized or depolarized and determines that the depolarization wave proceeds only if the adjacent segment is polarized. The operation of the simulated heart is displayed by showing an animation of the conduction of the depolarization waves in the pattern of electrophysiological pathways of the selected heart, by an ECG, and by a ladder diagram.
