WebOct 10, 2024 · Accurate MR-to-CT synthesis plays an important role in MRI-only radiotherapy treatment planning. In medical image synthesis, the cycle-generative adversarial network (CycleGAN) is becoming an influential method, however, its image quality of synthesis is not optimal yet. In this study, we proposed a new learning method … WebFeb 1, 2024 · Existing MR-based synthetic CT generation methods either use advanced MR sequences that have long acquisition time and limited clinical availability or use matching of the MR images from a newly ...
Cross-Modality Image Synthesis from Unpaired Data Using …
WebMethods: The DL-Recon framework combines physics-based models with deep learning CT synthesis and leverages uncertainty information to promote robustness to unseen features. A 3D generative adversarial network (GAN) with a conditional loss function modulated by aleatoric uncertainty was developed for CBCT-to-CT synthesis. WebMay 22, 2024 · 1. Introduction. Computed tomography (CT)-based radiotherapy [] is currently used in radiotherapy planning and is reasonably effective.However, magnetic resonance (MR) imaging delivers superior contrast of soft tissue compared with the CT scans []; therefore, radiotherapy devices using MR imaging [] are being developed.In … tso seating
Deep CT to MR Synthesis Using Paired and Unpaired Data
WebMay 22, 2024 · The MR-GAN has two structures—the paired cycle-consistent and unpaired cycle-consistent, to simultaneously train different data. The results of the MR-GAN using paired and unpaired data together indicate a better performance according to the quantitative and qualitative evaluations than using only one type of data.
