A Hybrid Diffusion Imaging Atlas in Q-space

Synopsis: The number of atlas construction methods for diffusion weighted imaging is at least equal to the number of possible models which can be reconstructed from the original data in q-space. Therefore, we aim at constructing an atlas before the reconstruction of any of these models: a hybrid diffusion imaging atlas containing signal functions for multiple shells of q-space. In this work, we show how this can be achieved by creating such an atlas (containing signal functions for b = 700, 1000, 2800) and reconstructing some possible models of diffusion (diffusion tensor and fiber orientation distribution function) from the result.Dhollander, T., Van Hecke, W., Maes, F., Sunaert, S., Suetens, P.: A Hybrid Diffusion Imaging Atlas in Q-space.
