Abstract:
1. A method for mapping a myocardium of a patient, comprising: recording a series of angiographic recordings of the patient directly after administering a contrast agent to the patient by an imaging recording device; determining a series of trend patterns of the contrast agent in the angiographic recordings by a computing unit; selecting a reference area in one of the angiographic recordings by the computing unit; defining the trend pattern of the one of the angiographic recordings in the reference area as a reference curve by the computing unit; calculating a series of correlation coefficients between the trend patterns and the reference curve by the computing unit; comparing the correlation coefficients with a threshold value by the computing unit; and mapping the myocardium based on the comparison by the computing unit to determine a perfusion in the myocardium, wherein the correlation coefficients are determined as follows: where X, Y are vectors of two time-intensity curves, c(X,Y) is the correlation coefficient of X and Y.
