## Abstract

Various embodiments include a system and method that provide fetal visualization. The method can include acquiring, by an ultrasound system, ultrasound data for a region of interest. The method may include computing, by a processor of the ultrasound system, a fetal measurement based on the acquired ultrasound data. The method can include generating, by the processor, a graphical model based on one or more of the fetal measurement and the acquired ultrasound data. The method may include displaying, at a display system, the computed fetal measurement and the generated graphical model.

## Claims
