The goal of this research is to explore the effect on image quality of including an additional LR view to the orthogonal super resolution geometry. The visual evaluation of this technique was performed in low resolution data sets simulated from isotropic high resolution data. The results of simulation indicate that the quality of an SRR image based on orthogonal acquisition may be improved by the addition of a fourth view acquired obliquely to the through-plane direction. Additionally, the observed increase in image quality would be worth the minimal increase in acquisition time required for one additional view.
