Description

Orthopedic imaging has traditionally relied on ionizing radiation based modalities such as x-ray, fluoroscopy and CT. We are investigating the employment of 3D US as an alternative safer imaging modality for a prospective minimally invasive computer assisted surgery system designed specifically for pre-operative bone fracture assessment and intra-operative guidance in fracture reduction procedures. We have demonstrated fracture detection (Figure 2, arrows) and have developed US-CT fusion methods to improve intra-operative visualization of bone surfaces (Figure 3).
