摘要： A method for anatomical imaging includes acquiring image data representative of three-dimensional volume segments of an image volume of interest in a subject. The image data are acquired in synchronism with corresponding physiological cycles of the subject. Each volume segment contains image data distributed in three dimensions. Acquiring image data includes selecting a sequence of scan lines for each respective volume segment configured to minimize an occurrence of motion artifacts throughout the image volume. The image data representative of the volume segments is combined to produce a representation of a three-dimensional anatomical image of the image volume.
