内容記述 | The conventional dynamic cardiac phantom used in the field of nuclear medicine has a structure for which the size of the external side of the heartis fixed and only the inner side moves anteroposterior. Therefore, its usefulness in technical evaluation is limited. Hence, we developed a new dynamic cardiac phantom in which the outer and inner membranes freely move. Using a SPECT/CT system, we performed validation by filling the myocardial layer of the dynamic cardiac phantom with solution and the ventricle part with contrast medium. We evaluated myocardial wall motions of 3 segments (basal, mid, and apical) by setting the stroke ratios at 20:20 (ventricle-to-myocardial layer ratio). The myocardial wall motions at the stroke ratio of 20:20 were 7.50 ± 0.44, 11.15 ± 0.56, and 9.90 ± 0.24 mm in the basal, mid, and apical segments, respectively. These results suggest that the use of this phantom can realize technical evaluation that presumes various clinical conditions. | |||||
