This paper proposes a method for locating the fetal mouth by registering 3D ultrasound images and a 3D fetal model. We construct a 3D fetal model with the anatomy of oral cavity and airways, which is used to help localize the position of fetal oral cavity and airways for fetal endoscopic tracheal occlusion (FETO) surgery, by the rigid registration with the extracted 3D fetal face surface from 3D ultrasound image. Through the registration, fetal oral cavity and airways, which cannot be distinguished clearly by 3D ultrasound image, can be visualized and localized in 3D ultrasound image.
