Tissue characterization of local myocardium using phase frequency spectrum of ultrasonic RF signal

Tissue characterization of local myocardium using phase frequency spectrum of ultrasonic RF signal

A new phase frequency spectrum (PFS) method is proposed to estimate regional myocardial tissue character and function during cardiac cycle. The analysis employs the small range centering on the point tracked by the tracking system of a RF signal, and applies time-frequency analysis (wavelet transfor...
