Registration process in Stereotactic Surgery – Yttrium Technology

Registration process in Stereotactic Surgery

Register the frame coordinate system with the image coordinate system.
Category: Computer Assisted Surgery
Technologies: C++, Gradient Descendant Algorithm, 3D texture Rendering guided by 2D Texture.
The problem to solve is to register the frame coordinate system with the image coordinate system. The frame is modeled by 9 lines forming three Z patterns (upper-left figure), this 9 lines are simultaneously adjusted to the frame traces over the images. A first approach is performed using the VNL library, and a fine adjustment is performed using a gradient descendant algorithm.
