Ct to mr synthesis

The key to the synthesis of MR images from CT images lies in how to obtain a mapping from the domain of CT images to the domain of MR images. CNNs have been shown as an effective way of learning such a mapping [15]. Given a CT image x, a CNN model parametrized by \phi maps x to an MR image y, … See more The detailed structure of the proposed network is shown in Fig. 1 and described here.
