Soterix Medical MEGA-TMS

Monophasic and Paired-Monophasic Transcranial Magnetic Stimulators. The most advanced TMS with unmatched strength and control

Soterix Medical introduces the most advanced Transcranial Magnetic Stimulation (TMS) system ever developed coupled with exceptional low electromagnetic interference and low heat output performance. The system (MEGA-TMS™) incorporates the highest maximum voltage rating capacitor (2800V) in the industry allowing generation of high power monophasic stimuli. These strong pulses ensure that evoked responses can still be elicited when coil is held at an increased distance from the scalp surface ‐ a requirement for combined TMS-EEG recordings. For standalone TMS recording, a higher maximum voltage rating not only results in good motor response at lower intensities but allows eliciting responses in people with decreased cortical excitability. Additionally, MEGA-TMS™ is the only TMS system that allows full control of device parameters using an API.

MEGA-TMS™ can be used in both single pulse mode and paired pulse modes. Two single pulses from MEGA-TMS™ stimulators can be summed to provide an industry leading single higher pulse - equal to 140% of a single MEGA-TMS™ machine.

MEGA-TMS™ can be used for a wide range of assessments ranging from triple stimulation technique, RMT, AMT, CCT, MEP, I-O curve, CSP, Motor Mapping, inter-hemispheric stimulation, etc.

MEGA-TMS™ can be used for the typical TMS guided diagnosis, assessment and monitoring of nervous diseases.
