This study introduces a pipeline that enhances ultrasound plane pose estimation for fetal brain imaging by providing continuous, real‑time proximity feedback to standard planes (SPs). It employs a semi‑supervised segmentation model achieving high mIoU scores on both SPs and non‑SPs, and integrates a classification step to filter out frames without the fetal brain. The system, validated on an NVIDIA Clara AGX edge device, runs at 39 Hz and has been tested on real scan videos from 17 sonographers, demonstrating its practical viability for clinical use.

AnatoProto is a lightweight sequence‑level framework that adapts a frozen BiomedCLIP encoder for detecting the fetal abdominal circumference standard plane in low‑cost obstetric blind sweeps. It incorporates anatomy‑weighted spatial pooling, a within‑case prototype loss, a three‑stage cascade refinement, and a hybrid prediction head to address the highly imbalanced, short‑segment nature of the task. On the ACOUSLIC‑AI benchmark, AnatoProto achieves a test F1 of 67.72, surpassing the best foundation‑model baseline by 13.20 F1 and the best video temporal‑action‑detection baseline by 15.76 F1.

The paper introduces Segment Anything Small (SAS), a data‑augmentation method that improves deep‑learning segmentation of small anatomical structures in ultrasound images. SAS uses two transformations: resizing and embedding organ thumbnails into a black background to vary organ scale, and adding noise to regions of interest to mimic tissue texture variability. Experiments on one internal and five external datasets show Dice score gains up to 0.35, with an average improvement of 0.16, and demonstrate that SAS enhances model robustness and generalizability without adding hallucinations or artifacts.
