Brain Tissue Microstructure Characterization Using dMRI Based Autoencoder Neural-Networks Imaging (dMRI) data. One of the main drawbacks of this approach is that the number of microstructural features needs to be decided a priori and it is embedded in the model definition. However, the number of microstructural features which is possible to obtain from dMRI data given the acquisition sc作者: motor-unit 時間: 2025-3-22 16:36
