[Development and assessment of real cardiac motion simulation phantom].
To evaluate cardiac images obtained by multi-slice CT, assessments of the temporal resolution and reconstruction algorithm are essential. For these purposes, we have designed and developed a cardiac motion phantom. Using suitable driver sequences, the phantom allowed for modeling of real left ventricular motion, which was characterized by fast pumping, slow pumping, fast filling and slow filling. Our phantom seems to be useful for use in the fundamental assessments and researches of cardiac CT.
