Abstract: |
Deep learning has been a hot topic and applied in various applications. However, a crucial requirement of deep learning in medical image applications is the ability to produce generalizable learning from small and often heterogeneous image sets. In this chapter, we will present some deep learning approaches for learning from small datasets. These approaches use the following idea: leverage information from a different related modality for learning. While approaches exist even for learning generalizable models from the same modality, we particularly focus on the problem where learning is done by using a different imaging modality such as computed tomography (CT) with MRI, T1-weighted MRI with FLAIR MRI, CT with positron emission tomography, etc. Learning using from different modalities is called cross-modality learning. © 2021 Elsevier Inc.
