Evaluation of the anatomical accuracy of the neuronavigation system “StealthStation” in neurosurgical operations
… was to evaluate the anatomical accuracy of the neuronavigation system StealthStation in neurosurgical operations, specifically in brain biopsy and PBC procedures; by assessing the efficacy, the targeting accuracy and the safety of the StealthStation navigated operations, compared with the …

Feasibility of Spinal Neuronavigation and Evaluation of Registration and Application Error Modalities Using Optical Topographic Imaging
Intra-operative navigation began with the localization of subsurface structures in cranial neurosurgery using frame-based stereotaxy. Advances in imaging and computing power have led to the development of modern frameless three-dimensional (3D) computer-assisted navigation (CAN), employed across …

Electrode and Headgear Design for Accurate TDCS
… system, transcranial magnetic stimulation or neuronavigation. These various methods require highly trained technicians, are extremely expensive, and magnetic stimulation and neuronavigation are not mobile enough to be done outside a clinical setting. After the time consuming routine of finding …

PET-imaging in depression and antidepressant therapies : focus on the serotonin system and the cerebral glucose metabolism
… of the accuracy of a for rodents adapted human neuronavigation system to perform rTMS in the rat. A second objective was the investigation of the construct validity of two depression models in terms of altered regional glucose metabolism. This was investigated via a PET study using the …

Optimizing the neuromodulation of pathological neural circuits: multiparametric approaches and biomarker prediction
… cost and time it usually takes for conventional neuronavigation-based TMS protocols to take effect in severe suicidal MDD cases, I tested a novel dual-site accelerated TMS protocol using an EEG 10-20 system-guided approach in a double-blind randomized controlled trial of 20 sessions over five …

Improving the reliability of transcranial magnetic stimulation targeting
… of the electric field maximum is targeted with a neuronavigation system that shows the coil placement and the peak electric field on a brain image. To find a suitable stimulation location and orientation, the TMS operator gives pulses with varying stimulus parameters and observes the responses, …

Finite Element Modeling Driven by Health Care and Aerospace Applications
… Imaging (MRI) in image-guided neurosurgery. Neuronavigation with deformable registration of preoperative MRI to intraoperative MRI allows the surgeon to view the location of surgical tools relative to the preoperative anatomical (MRI) or functional data (DT-MRI, fMRI), thereby avoiding damage …
