A method for ultrasound imaging in the presence of contrast agents, particularly in the field of cardiology, including the following steps: detecting physiological, especially electrocardiographic signals (ECG); transforming said signals or a part thereof into pulses for controlling an ultrasonic probe pointed to the heart region, to synchronize it with the heart cycle; performing image acquisitions (A1, A2, A3, A4, A5, A6, A7, A8) at predetermined heart cycle phases (T1, T2) for predetermined limited times, with a predetermined ultrasonic beam intensity (I); processing the received signals and displaying them on a display. Image acquisition takes place in the systolic phase (T1-T2) of each heart cycle from the end of diastole (R, T1) to the end of systole (T2), a certain fixed number of acquisitions (8, n) per unit time and an intensity (I) of the ultrasonic beams being determined with the help of an intermediate Mechanical Index for controlled destruction of a certain percentage of contrast agent microbubbles. <IMAGE> |
