Deep Learning‐Based Inclusion Boundary Identification Using Wave Propagation in Optical Coherence Elastography

Guangyu Zhang, Jinpeng Liao, Zhengshuyi Feng, Alison Layton et autres

Elastography is widely used to estimate tissue mechanical properties based on wave propagation characteristics. However, a major limitation is that elastography maps often fail to accurately delineate internal boundaries within heterogeneous tissues. To address this issue, we propose a novel deep learning-based …
