摘要

Deep learning methods have been applied to fetal head circumference (HC) estimation from ultrasound images. However, accuracy remains limited in biomedical applications. This paper proposes a constructive learning approach to improve segmentation of fetal head regions. The method uses B-spline functions and pruning mechanisms to reduce overfitting and optimize network structure during training. The proposed approach requires high-performance computing for training large-scale models with repeated validation runs and parallel B-spline calculations across multiple network layers. Evaluations on ultrasound datasets show improved accuracy with DSC of 98.43% and reduced overfitting compared to baseline methods. The method achieves 2% improvement in HC detection and reduces overfitting risk by half.
