CA 2504668
The invention relates to a triggered ultrasound imaging method for imaging of the myocardium, minimizing the risk of eliciting cardiac arrhythmia. Particularly, the invention is directed to a method of assessing cardiac perfusion. Destruction pulses are triggered such that they fall within the refractory period of the heart, while imaging pulses are triggered at any given time of the ECG cycle, preferably during end-systole.
La présente invention concerne un procédé d'imagerie par ultrasons synchronisés qui permet de former une image du myocarde en minimisant le risque de déclencher une arythmie cardiaque. En particulier, l'invention se rapporte à un procédé permettant d'évaluer l'irrigation cardiaque. Selon l'invention, les impulsions de destruction sont synchronisées de telle manière qu'elles tombent dans la période réfractaire du coeur, tandis que les impulsions d'imagerie sont déclenchées à un quelconque moment donné du cycle de l'ECG, de préférence pendant la télésystole.
