Abstract

The phase-stepping (PS) mode of X-ray Grating Talbot interferometer (XGTI) data processing technique can yield high-spatial resolution images, albeit with lower throughput since each projection of a tomogram requires at least five phase-stepping images. To overcome this problem, we can use a setup with only a single phase grating in combination with a high-resolution detector system and a Spatial Harmonic Imaging (SHI) technique. The latter technique makes use of the fact that a Talbot interferogram consists of carrier frequency spectrum of the grating overlapping with the sample spectrum and by Fourier transforming the interferogram we can separate the two. The disadvantage of this is that the spatial resolution is inferior. In this manuscript we will compare these two single grating data processing techniques using a single data set measured with mouse embryo heart and discuss advantages and disadvantages of each technique. These two techniques can be used as complementary; one for high resolution, and the other for high-speed imaging.
