Ct to mr synthesis
Did you know?
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. Our network is based on a variant of the U-net developed … See more All MR images are preprocessed before being fed into the network. First, the intensities of MR images are normalized to be in the range of … See more WebThe synthesis of computed tomography (CT) images from magnetic resonance imaging (MR) images and segmentation of target and organs-at-risk (OARs) are two important tasks in MR-only radiotherapy treatment planning (RTP).
