Cardiac cine magnetic resonance imaging is a valuable technique for assessing cardiac function. However, conventional cardiac cine imaging is based on breath-holding and ECG-triggering, which has particularly difficulty to be used for the diagnosis of the patients with arrhythmia. In this work, a novel technique for real-time cardiac cine imaging was developed and used to evaluate the left ventricular (LV) function in patients with arrhythmia. Preliminary experiment results demonstrated that the proposed method can accurately evaluate patient’s LV function without the use of ECG triggering and improve the image quality of the patients with arrhythmia.
