Project Description

We are initiating a multi-center (led by Dr. Emet Schneiderman) study to understand the impact of maternal obstructive sleep apnea (OSA) and different treatment plans (i.e., mouth appliances) on both pregnant women and fetuses, including fetal craniofacial dysmorphology and growth issues. A large sample size of ultrasound images will be collected. However, the fetuses may have different poses and partial face covered, and the ultrasonographic images have lots of noise. We are interested in using statistical modeling to refine 3D segmentation to diagnose fetal orofacial dysmorphology, reconstruct 3D growth trajectories, explore epigenetic effects of facial growth problems and dysmorphology, predict newborn facial shapes, etc.

Objective

1. Use statistical shape modeling tools from Slicer and Kitware to refine 3D reconstruct of fetal faces based on ultrasonography.

Approach and Plan

1. Learn and explore techniques in statistical shape modeling and ultrasound image processing using 3D slicer and other tools developed by Kitware; set up a plan.
2. Locate sample data for experimenting.
3. Develop potential collaborations

Progress and Next Steps

1. Preparing grant application and data collection plans
2. See above
