Intraoperative Computed Tomography and Finite Element Modelling for Multimodal Image Fusion in Brain Surgery.

Background: intraoperative computer tomography (iCT) and advanced image fusion algorithms could improve the management of brainshift and the navigation accuracy.

Objective: To evaluate the performance of an iCT-based fusion algorithm using clinical data.

Methods: Ten patients with brain tumors were enrolled; preoperative MRI was acquired.
