Clinical workflow of sonographers performing fetal anomaly ultrasound scans: deep learning‐based analysis

Despite decades of obstetric scanning, the study of sonographer workflow remains largely unexplored. The UK guidelines specify that an image or video clip of five different anatomical regions must be stored, and these were detected in the majority of scans: head and brain 97.2%, coronal face view 86.1%, abdomen 93.1%, spine 95%, and femur 92.3%. Overall, each anomaly scan was found to be unique in its scanning sequence, suggesting that sonographers take advantage of the fetal position and acquire the standard planes according to their visibility rather than following a strict acquisition order.
