| 目的：应用超分辨技术提高肾脏血流超声造影成像的空间分辨率。方法：提出一种基于造影图像序列统计变换的超声衍射衰减显微镜,并应用到人体肾脏超声造影的图像重建中。通过与最大强度投影成像结果相对比,来探究超分辨成像对于空间分辨率的改善效果。结果：与最大强度投影结果相比,超分辨成像对于肾脏血流显示的空间分辨率从视觉上显著提高。结论：超声衍射衰减显微镜可以对临床采集的肾血流造影视频进行重建并提高成像的空间分辨率,为观察微小血流结构提供了新的有效手段。 |

| Objective：To explore the performance of super-resolution ultrasound in improving the spatial resolution of CEUS imaging in human kidney.Methods：A new super-resolution ultrasound imaging method based on statistics transformation of CEUS image sequence termed ultrasound diffraction attenuation microscopy (UDAM) was proposed and applied in the kidney. The result of UDAM was compared with maximum intensity projection (MIP) to explore its improvement on spatial resolution.Results： The spatial resolution was significantly improved in visual using UDAM compared with the MIP result.Conclusion：The ultrasound diffraction attenuation microscopy can enhance the spatial resolution using clinical CEUS images of the kidney, which provides a new effective means for observing microscopic blood flow structure. |
