Motion of the abdominal aorta during DCE-MRI. (a) Abdominal aorta motion during 187 seconds of DCE-MRI (89 time frames) of a representative patient. Each circle represents the edge of the segmented aortic region at each time frame. Initial center position of the aorta was (0, 0), and its radius was 9 mm. Color scale represents the number of overlapped circles. (b) Trace of center position of the aorta shown in Fig. 2a. (c) Box plots of aorta maximum and mean displacements from the initial aortic position
