Patent ID: 7939093

Claim:
A method for representing a myocardial tissue of a patient, comprising: administering a contrast agent to the patient; inputting a patient-specific parameter that relates to a speed of perfusing the contrast agent by a myocardial tissue and eliminating the contrast agent from the myocardial tissue; calculating a time at which a difference between a content of the contrast agent in a necrotic myocardial tissue and in a non-necrotic myocardial tissue attains a maximum value based on the patient-specific parameter; performing a late-phase CT scan for detecting the necrotic myocardial tissue compared to the normally perfused myocardial tissue at the calculated time; and representing the necrotic myocardial tissue and the normally perfused myocardial tissue for medically examining the patient, wherein the maximum value of the difference in the content of the contrast agent is calculated by: S m , n , o ⁡ ( t ) = m · ⅇ ( t + t const ) - n · ( t + t const ) o wherein: S(t) is a time-dependent approximation function for a response of a contrast agent signal intensity versus time, m, n and o are constants derived from the patient-specific parameters, t const is a time after which the contrast agent has been flushed out of the normally and the less perfused myocardial tissues, and t is the time with which the contrast agent signal intensity varies and is zero at t const .
