Enhanced Intraoperative Visualization for Brain Surgery: A Prototypic Simulated Scenario
Zein Salah, Bernhard Preim, Amir Samii, Rudolf Fahlbusch, Georg Rose · CURAC · 2010
Due to the required high precision and reliability, image guidance is increasingly being adapted in neurosurgery, where correspondences between the patient and scanned data are viewed on multiple displays. In this paper, we present a prototype for an augmented reality system that provides enhanced intraoperative visualization within the optical surgery microscope image. For this purpose, relevant targeted and risk structures are extracted from registered patient data and overlaid on the real scene. Similarly, supportive information of underlying anatomy can be superimposed, which includes, amongst others, shape and depth information of tumors, and interactively selected tomographical slices. The overall advantage is a more ergonomic hand-eye coordination, a more accurate delineation of targeted structures and better protection of risk anatomy.
