Design of a neurosurgical procedure model for multimodal image-guided surgery
نویسندگان
چکیده
In multimodal image-guided surgery, surgeons have to manage large amounts of information (i.e. images) to plan and perform the surgical procedure. To facilitate management we attempted to model the procedure as a set of distinct steps with a UML class diagram. To each step we assigned a list of relevant image entities extracted from multimodal images and an action describing the purpose of the step. Each image entity was attributed a role that may differ with the step. Our generic information model helps surgeons anticipate surgery, and may contribute to develop simulation and even teaching tools. It may also be used to adapt visualization and interaction modes in neuronavigation. Finally it provides a framework to model the knowledge involved in neurosurgical procedures in the context of image-guided surgery of the central nervous system.

Models of Surgical Procedures for Multimodal Image-Guided Neurosurgery
Improvement of image guided surgery systems requires a better anticipation of the surgical procedure. This anticipation may be provided by a better understanding of surgical procedures and/or the use of information models related to neurosurgical procedures. We are introducing a generic model of surgical procedures in the context of multimodal image-guided craniotomies. The basic principle of t...

After the introduction of MRI, new modalities facilitated the procedure of surgical planning to achieve the microsurgical goal and improve prognosis and quality of life in patients. Despite the variable applications of preoperative and intraoperative mapping and monitoring systems, several limitations and concerns are reported for every modality as well. In this issue of the IrJNS, we are delig...
