A superresolution algorithm was applied to spatially shifted, single-shot, diffusion-weighted brain images to generate a new image with increased spatial resolution. Detailed two-dimensional white matter fiber tract maps of the human brain resulting from application of the technique are shown. The method provides a new means for improving the resolution in cases where k-space segmentation is difficult to implement. Diffusion-weighted imaging and diffusion tensor imaging in vivo stand to benefit in particular because the necessity of obtaining high-resolution scans is matched by the difficulty in obtaining them.

一种超分辨率算法被应用于空间移位的单次扩散加权脑图像，以生成具有更高空间分辨率的新图像。展示了应用该技术得到的详细的人脑二维白质纤维束图。该方法为在难以实施k空间分割的情况下提高分辨率提供了一种新手段。活体中的扩散加权成像和扩散张量成像尤其有望从中受益，因为获取高分辨率扫描的必要性与获取它们的难度相当。《磁共振医学》45:29 - 35, 2001年。
