Abstract

To diagnose cardiac malfunctions, various imaging techniques have been applied to heart : DSA(Digital Subtracted Angiography), Doppler Ultrasound, MR Angio. But it is difficult to observe three dimensional heart motion which is the most intuitive tool for diagnosis, only by using these methods. In this research, we have suggested 4-Dimensional reconstruction scheme of heart motion images that can be acquired by ECG-gated cine MR imaging. One cardiac cycle was devided into $9\sim15$ phases and for each phase 3D reconstructed volumn heart was made. We can observe 3D volumns along the cardiac cycle, time. So the results were 4-D reconstructed data.
