RecView is a program for tomographic reconstruction with graphical user interfaces. It's consisted of about 9,000 lines of originally-written source codes in C++, CUDA C, x86 and x64 machine languages including SIMD instructions. RecView is developed for processing tomographic data obtained at the BL20B2, BL20XU, and BL47XU beamlines of the synchrotron radiation facility SPring-8.Three-dimensional structural analysis by SR computed tomography is performed by recording two-dimensional radiographs. Then the three-dimensional structure is determined by the convolution back-projection method. This reconstruction calculation is repeated for each tomographic slice, giving the three-dimensional structure. Therefore, the resolution in the tomographic slice should be affected by the reconstruction calculation. We examined the resolutions in the tomographic slice plane and perpendicular to it from modulation transfer functions. The through-plane resolution perpendicular to the tomographic slice corresponded to the spatial resolution of two-dimensional radiographs. In contrast, the in-plane resolution within the slice was approximately 1.5-times larger than the through-plane resolution. Real-space interpolation was performed prior to the tomographic reconstruction, giving an improved in-plane resolution.RecView is available free of charge for all researchers.
