ROI-Guided Echocardiographic Image Analysis and Case Aggregation for Differentiating Atrial and Ventricular Septal Defects
This study implemented strict subject-disjoint partitioning to eliminate data leakage, and simultaneously introduced cross-frame case aggregation to emulate the multi-frame visual synthesis process of expert echocardiographers, suggesting that the proposed workflow has the potential to serve as an adjunctive tool for septal defect screening.
