Conventional cardiac cine imaging is based on ECG-triggering, which is difficult to be used in arrhythmic patients. Real-time cardiac cine technique based on radial sampling scheme is an alternative approach for imaging the arrhythmic patients. However, the technique is often hampered in trajectory error due to system gradient delay. To address this issue, a novel real-time cardiac cine technique was developed based on a radial bSSFP sequence with trajectory error auto-correction. Preliminary results demonstrated that the proposed technique can improve the image quality and has potential to be clinically useful for the arrhythmic patients.
