Small objects, called trackers, are attached to the TMS coil, and the subject. These trackers are monitored, or "seen" by an optical position sensor (optical camera). This information is send to a computer which, after a calibration procedure, displays the position and orientation of the coil on the subject's individual MRI.

Thus, Localite TMS Navigator helps to position the coil very precisely in reference to the subjects brain shown in an individual anatomical MR dataset.

Information sheets on how to use the Localite are available in the TMS lab. The complete Localite manual is available at the labmanager (Dennis Schutter).

==== Vive ====
 
As of November 2016, standard HTC Vive setups are available in both RIVER Labs. These setups use the Vive's own "Lighthouse" tracking system instead of the lab's, and a standard [[Computers#Lab_Computer | Lab Computer]] (with upgraded graphics card). No wireless solution is available for the Vive (yet<ref>http://uploadvr.com/htc-vive-wireless-kit/</ref>), so the tracking area is limited by the length of the cable and the range of the Lighthouse tracking system.
 
As of September 2017, the Vive in RIVER Lab 2 has been equipped with the Deluxe Audio Strap, which has built-in headphones.

MagVenture TMS stimulator

In the TMS lab, two MagPro X100 TMS stimulators available, one of them has the 'option' included, as described below.

• MagVenture X100 system

The core of the setup is the MagVenture MagPro X100 with option stimulator. This system is capable of producing 4 types of waveforms, namely: 1) Biphasic, 2) BiPhasic Burst, 3) Half Sine 4) MonoPhasic

The MagOption added to the MagPro X100 also gives it the following enhanced stimulation capabilities for Biphasic, Half Sine and Monophasic: 1) Dual pulses with up to 20 pulse pairs per second repetition rate 2) Advanced power pulse feature adding 40% additional stimulation power

• MCF-B65 spoel, butterfly, statisch gekoeld

Localite TMS Navigator System

Localite TMS Navigator is an image-guided tool to assist in the positioning of a transcranial magnetic stimulator (TMS) coil over a subject's brain. The Localite system includes the software, position sensor and all the related hardware (except the TMS-stimulator) to perform image-guided TMS. Small objects, called trackers, are attached to the TMS coil, and the subject. These trackers are monitored, or "seen" by an optical position sensor (optical camera).

Thus, Localite TMS Navigator helps to position the coil very precisely in reference to the subjects brain shown in an individual anatomical MR dataset. Information sheets on how to use the Localite are available in the TMS lab. The complete Localite manual is available at the labmanager (Dennis Schutter).
