The speckle-based scanning method for x-ray phase-contrast imaging is implemented with a liquid-metal-jet source. Using the two-dimensional scanning technique, the phase shift introduced by the object is retrieved in both transverse orientations, and the limitations on spatial resolution inherent to the speckle-tracking technique are avoided. This method opens up possibilities of new high-resolution multimodal applications for lab-based phase-contrast x-ray imaging.
基于散斑的X射线相衬成像扫描方法是通过液态金属射流源实现的。利用二维扫描技术，在两个横向方向上获取物体引入的相移，避免了散斑跟踪技术固有的空间分辨率限制。该方法为基于实验室的相衬X射线成像开辟了新的高分辨率多模态应用的可能性。
