The highly-constrained projection reconstruction (HYPR)-based algorithms provided high spatio-temporal images by using the composite information. However, HYPR-based methods have limitation that only can reconstruct magnitude image. In the proposed method, we provide a novel method to recontruct complex-valued image and apply the method to phase contrast imaging.
