Project Description

Objective

• Use ultrasound to verify proper position of mandibular condyle during orthognatic surgery

Approach, Plan

• Use tracking to create 3D ultrasound image and register it with preop CT

Progress

• Preliminary results available
• Paper submitted to a MICCAI/AECAI2015 workshop.

Meeting goals

Project week goals are discussions for improvement of

• 3D reconstruction algorithm parameters (minor improvement)
• Ultrasound image post-processing (no improvement)
• Scanning aspects related to repeatability (important new information)
• Bone segmentation considerations (important new insights)
