| Research Abstract |
Objective: The aim of this pilot study presents a novel approach to visualize the architecture of placenta using the three-dimensional (3D) ultrasound machine, and then these data restructure the placental architecture using 3D Slicer software.Methods: Six normal, singleton pregnancies from 12 to 20 weeks. We used a Voluson E6. 3D volume image adjusted to include the entire placenta. The 3D volume image reconstruction of the placenta using Grow Cut and the manual segmentation and the label statics analysis. Results: Two-variable regression analysis of Label Statistics showed the count (R2=0.04), and the volume (R2=0.09). The anterior of the uterine wall, the placenta and part of the umbilical cord was separated by Grow Cut Segmentation using ultrasound image at 13 weeks. Manual Segmentation demonstrated visualization of the placental architecture.Conclusions: This pilot study presented 3D reconstruction of the placenta based on ultrasound imaging using 3D Slicer.
