Owing to the unique penetrating character of X-rays and the high intensity, quasi-coherence of the synchrotron radiation beams, more and more advanced imaging techniques based on synchrotron radiation facility are proposed and developed to realize three dimensional, high resolution, dynamic and nondestructive imaging for different samples. With the development of synchrotron radiation facility and the experimental techniques, multidimensional (space, time, pressure, spectrum, and so on...) multi-scale (from nm to mm) and in situ imaging technique is developing rapidly and it has attracted many scientists attention in different fields. In order to further promote the synchrotron radiation imaging techniques and applications, the "Symposium on Multi-scale and Multi-dimensional Synchrotron Radiation Imaging Techniques and Applications (MMSRI-2015)" will be held in Shanghai on 3-6 Nov. 2015. The Symposium will focus on the latest developments in instruments, methods and application for synchrotron radiation based imaging.
