In most small animal imaging studies both long axis (coronal or sagittal) and short axis (axial) images of the region of interest are obtained. The goal of this study is to explore whether combining two orthogonal views obtained with different slice-select directions could reduce the motion artifacts and improve image quality. The advantages of this method are that no a priori knowledge or external hardware is needed and it doesn’t increase the acquisition time. The results show that it is advantageous to use the available orthogonal image(s) to improve the image quality by reducing ghosting artifacts caused by motion.
