BACKGROUND AND PURPOSE FUS-induced BBB opening is a promising technique for noninvasive and local delivery of drugs into the brain. Here we propose the novel use of a neuronavigation system to guide the FUS-induced BBB opening procedure and investigate its feasibility in vivo in large animals. MATERIALS AND METHODS We developed an interface between the neuronavigator and FUS to allow guidance...

BACKGROUND A neuronavigation interface with extended function as compared with current systems was developed to aid during temporal bone surgery. The interface, named EVADE, updates the prior anatomical image and visualizes the bone drilling process virtually in real-time without need for intra-operative imaging. Furthermore, EVADE continuously calculates the distance from the drill tip to segm...

Endoscope, microscope, and neuronavigation systems are integrated in neurosurgical procedures mainly by using a serial combination algorithm, where, the user must switch his/her field of view from one platform display to another. The integration of theses devices could be optimized by incorporating different displays into one viewing platform thus achieving a parallel combination. In this study...

Frameless stereotactic neuronavigation system has been in wide use since many years for precise localization of cranial tumors and navigation for spinal instrumentation. We present its usage in the localization of odontoid process in a very high basilar invagination for a transoral transpalatal resection of the same. We discuss the technical aspects of assembly of neuronavigation system, O-arm ...

Sun et al. have invented a new stereotactic instrument[1], which is thought to bridge the differences between frameless and frame-based techniques. It consists of a stereotactic frame, which is attached to the skull in a manner comparable to classical stereotactic frames. Instead for guidance of a linear instrument, as for example in the case of a frame-based stereotactic biopsy, it is connecte...

AIM The result of surgical resection for insular high-grade glioma (HGG) is disappointing due to the complex anatomy of insula and aggressive growth of HGG. The use of intraoperative magnetic resonance imaging (iMRI) was reported to improve the results of glioma surgery. The authors aimed to evaluate the impact of high-field iMRI and functional neuronavigation on the surgical resection of insul...

OBJECTIVE The aim of this study was to assess the precision and feasibility 3D-printed marker–based augmented reality (AR) neurosurgical navigation its use intraoperatively compared with optical tracking neuronavigation systems (OTNSs). METHODS Three-dimensional–printed markers for CT MRI intraoperative were applied mobile devices using an AR light detection ranging (LIDAR) camera. 3D segmentat...

Ommaya reservoir placement has been an option for patients requiring cerebrospinal fluid (CSF) access since the 1960s. It is preferred to repeat lumbar punctures, both in terms of patient comfort and the consistency of intrathecal drug concentration. Technological developments have advanced the placement technique, allowing for better accuracy and reduced complications. Freehand placement was f...
