Fig. 2: Total weight of the pulsating cardiac phantom (Fuyo co., Tokyo, Japan) to simulate real heart motion is 40kg. It consisted of the driver, the control, the support, the balloon phantom and the ECG.
Fig. 3: Scans were performed in simulation mode of Cardiac Trigger Monitor. Simulated heart rates were fixed at 60 beats per minute during scans.
Fig. 4: Tilt angles (X-axis angles) of cradle were measured using digital inclinometer that New ipad have Gyroscope sensor. A application of New ipad was using by Gyro Toolbox HD.
Fig. 5: Two independent radiologists scored independently the severity of stair-step artifacts at each MPR images from 1 to 4 as follows:
If there are not discontinuity of adjacent center of two vessels ; excellent, score of 1 (white arrow at fig. A)
If there are discontinuity of 1-10% from adjacent center of two vessels ; good, score 2 (white arrowhead at fig. A)
If there are discontinuity of 11-20% from adjacent center of two vessels ; fair , score of 3 (black arrowhead at fig. B)
If there are discontinuity of more than 21% from adjacent center of two vessels ; poor, score of 4 (black arrow at fig. B)
