3D Surface Reconstruction of Spinal Ultrasound Images Based on 2D Contour Line

Methods of 3D reconstruction of medical images mainly included surface and volume reconstruction at present. In the experiment of 3D ultrasound reconstruction for spine of people, the result using volume reconstruction was unsatisfactory because of the ultrasound images' characteristic. So, we brought forward a method which was based on contour line to reconstruct 3D surface of spine. In this paper, we collected spinal ultrasound images using 3D freehand ultrasound firstly; next, tracing spinal contour line of each ultrasound images manually; finally, we used these contour lines to reconstruct spinal surface. The result showed that spinal surface reconstruction based on 2D contour line was close to real spinal surface, it could give physicians a better help in diagnosis of the spine.
