Purpose: Neuronavigation based on preoperative imaging data is a ubiquitous tool for
image guidance in neurosurgery. However, it is rendered unreliable when brain shift …

Intraoperative brain shift during neurosurgical procedures is a well-known phenomenon
caused by gravity, tissue manipulation, tumor size, loss of cerebrospinal fluid (CSF), and use …

Conventional image-guided neurosurgery relies on preoperative images to provide surgical
navigational information and visualization. However, these images are no longer accurate …

Purpose Brain shift during neurosurgical procedures must be corrected for in order to
reestablish accurate alignment for successful image-guided tumor resection. Sparse-data …

Navigation systems are commonly used in neurosurgical operating theaters. Generally, they
either rely on the use of preoperative or intraoperative image data. Using preoperative …

OBJECTIVE Preoperative magnetic resonance images (pMR) are typically coregistered to
provide intraoperative navigation, the accuracy of which can be significantly compromised …

To carry out effective and safe neurosurgical interventions for patients with brain lesions,
precise information about the unique structural and functional anatomy of that patient is …

Objective To evaluate the clinical application of 3-T intraoperative magnetic resonance
imaging (iMRI), awake craniotomy, multimodal functional mapping, and intraoperative …

With the recent advances in computing, the opportunities to translate computational models
to more integrated roles in patient treatment are expanding at an exciting rate. One area of …

Background Finite element models for estimation of intraoperative brain shift suffer from
huge computational cost. In these models, image registration and finite element analysis are …
