摘要： A cross-sectional area calculation section calculates a cross-sectional area of a subject as physical quantity with respect to a size of the subject, and an NEC calculation section calculates a noise equivalent count NEC as physical quantity for evaluating an image. The C-NEC calculation section calculates a noise equivalent count per unit area C-NEC as physical quantity for evaluating an image as per size of the subject in accordance with the cross-sectional area of the subject calculated in the cross-sectional area calculation section and the noise equivalent count NEC calculated in the NEC calculation section. Accordingly, the noise equivalent count per unit area C-NEC is calculated as noted above, whereby an index may be determined that is independent of the cross-sectional area of the subject in evaluating the image.
摘要翻译： 横截面积计算部根据被检体的尺寸，将被检体的截面积作为物理量进行计算，NEC计算部计算作为评价图像的物理量的噪声当量计数NEC。 C-NEC计算部分计算每单位面积C-NEC的噪声等效数量，作为根据在横截面积计算部分中计算的对象的横截面积来评估与被检体的大小相对应的图像的物理量 和NEC计算部分中计算的噪声等效计数NEC。 因此，如上所述计算每单位面积C-NEC的噪声等效数，由此可以确定在评估图像时与被摄体的横截面积无关的指标。
