摘要：

Objectives To evaluate the accuracy and reliability of a new ultrasound technique for the automatic assessment of the head-perineum distance (HPD) during childbirth. Methods HPD was measured on a total of 40 acquisition sessions in 30 laboring women both automatically by an innovative algorithm and manually by trained sonographers, assumed as gold standard. Results A significant correlation was found between manual and automatic measurements (Intra-CC = 0.994). High values of the coefficient of determination (r(2)=0.98) and low residual errors: RMSE = 2.01 mm (4.9%) were found. Conclusion The automatic algorithm for the assessment of the HPD represents a reliable technique.
