This paper presents a technique to reconstruct 3D breast ultrasound images at high resolution from anisotropically degradated volume acquisitions. Volumes are acquired by scanning the breast tissue with a 2D probe at different an gles, showing different directional degradations induced by the point spread functions. We present a new tech nique to reconstruct the original volume based on estimat ing the spatial degradation from orthogonal views, and re constructing the original volume through a regularized op timization technique. Results on synthetic and in vivo data show a better performance of this method in comparison to other spatial compounding techniques.
