Abstract :
A quantification methodology is proposed for the analysis of Doppler tissue imaging (DTI) M-mode images. After an enhancement stage, the cardiac wall is divided into several layers from which time curves and parameters are computed. A clinical study has been carried out, comparing normal and ischemic patients, in order to characterise the most relevant parameters that assess the intramyocardial left ventricle function. Results show that cross correlation and Fourier analysis may constitute a sensitive test for intramyocardial dysfunction during ischemia
