Doctors often need to manually adjust the 2-dimensional (2D) ultrasound probe to obtain a standard cranial plane for conducting fetal cranial ultrasound radiomics analysis, a process that is both challenging and time-consuming.

This task enables the contrastive learning model to learn the features of 2D slices at different spatial locations. Then, an automated spatial sampling method is used to construct a retrieval database that contains anatomical and spatial information for slices at various positions, which is used to perform spatial registration of 2D slices at arbitrary locations.</div></div><div><h3>Results:</h3><div>We evaluated our method using 39 cases of mid-gestation 3D ultrasound data from the hospital.
