title: Fetal biomodelling.
abstract: A study has been performed to determine if a stereolithographic (SL) biomodel of a fetal face could be created from 3 dimensional (3D) ultrasound (US). 3D ultrasound images were acquired by Diasonics Gateway 2D Array ultrasound systems (Diasonics Ultrasound, San Jose, CA, USA) using an electromagnetic localizer (Tomtec Free Hand Scanning Device, Tomtec Imaging Systems, Middle Cove, Australia). 3D volumetric reconstruction of the fetal face was performed and the data was prepared to guide the construction of an exact solid biomodel by stereolithography (SLA 250 3D Systems, Valencia, CA, USA). A faithful solid representation of the fetal face was produced within 12 hours of the US scan. The fetal biomodel seemed to improve the display of the 3D data. The user-friendly nature of biomodelling may have clinical utility for fetal morphological assessment and as an aid when counselling parents.
