Abstract

Neuronavigation is a guidance system that identifies lesions and plans the trajectory to the lesion to improve surgical outcomes. Frame-based systems, which involve head fixation by means of framing before imaging, are highly accurate. However, due to some limitations of frame-based systems, frameless systems that do not require frame fixation of the head have become popular and are widely used. Frameless systems require a registration step to establish the spatial relationship between the patient’s head and the image. Multiple types of registration methods and device tracking systems have been developed. Frameless systems are technically advanced and have demonstrated reliable accuracy, but these systems still have many occurrences of error and inherent limitations. Therefore, it is important to understand the principles and pitfalls of frameless systems to use them effectively and safely during surgical operations.
