An electrocardiography (ECG) synchronization technique allowed triggering of 1.5-T echo-planar acquisitions of the heart, with high gradient slew rates. In 51 volunteers (37 men and 14 women, aged 21-48 years), the ECG signal was amplified, filtered, and converted into an optical signal directly above the heart and was transmitted optically outside the bore. Reliable and artifact-free ECG tracings were obtained in all cases, regardless of the gradient switching speed.
一种心电图（ECG）同步技术能够触发心脏的1.5-T回波平面采集，具有高梯度切换率。在51名志愿者（37名男性和14名女性，年龄21 - 48岁）中，ECG信号被放大、滤波，并在心脏正上方转换为光信号，然后通过光传输到磁体孔外。无论梯度切换速度如何，所有情况下均获得了可靠且无伪影的ECG描记图。
