DuoMag XT


Repetitive transcranial magnetic stimulation (rTMS), delivered by the DuoMAG XT rTMS system, can be applied to increase or decrease the excitability of the corticospinal tract depending on the intensity of stimulation, coil orientation, and frequency.

Available in three different iterations and a multitude of different configurations, the DuoMAG XT is the flagship rTMS device available from Brainbox. With a focus on user-friendliness, proprietary software houses a powerful 5kHz EMG software for the recording and analysis of MEP’s, patient data and session history can be saved, exported and anonymised, and a purpose built protocol builder enables allows for the simple creation of rTMS trains and theta burst protocols for both research and clinical applications.

The range topping DuoMAG XT100 is capable of delivering 100Hz stimulation at 40% stimulator output and theta burst at 67% stimulator output. DuoMAG XT35 and XT10 stimulators are capable of delivering rTMS at 35Hz and 10Hz respectively.

Brainbox understand the need for flexible solutions within the workspace, and so are proud to offer the DuoMAG XT in three different configurations. A desktop set up can be requested for laboratories without the available space for cart, for those who’d prefer a more portable solution, the DuoMAG TMS cart with coil arm allows the stimulator and optional touchscreen computer to be moved easily between sites. Finally, popular in clinical institutions is the counterbalanced electromagnetically operated coil arm, keeping the coil position stable during longer rTMS sessions.

All DuoMAG XT stimulators can be controlled externally via TTL, USB 2.0 or via ethernet connection for flexible research applications.


Intuitive software allows for the easy control of subject database, including fully anonymising data and exporting stimulation history. A dedicated screen for the calculation of resting motor threshold (RMT) and active motor threshold (AMT), with the ability to add/edit cursors to highlight amplitude/latency.

The DuoMAG XT's custom protocol editor enables the customisation of all stimulation parameters, including repetitive trains, stimulation frequency, burst frequency, and stimulation at a percentage of motor threshold. 


Following the delivery of a TMS pulse in single pulse mode, the DuoMAG EMG software is configured to record and plot the highest and lowest peaks of the resulting motor evoked potential (MEP). Latency information can be added, together with manipulation of the cursors where necessary.

MEP data is stored and used for the calculation of stimulator intensity when delivering repetitive TMS (rTMS) protocols.

All MEP data and information can be exported in multiple formats for offline analysis.


When calculating an active motor threshold (AMT), it is first necessary to record the participant's maximum voluntary isometric contraction (MVIC) before performing a contraction to a target percentage of this value.

A built-in feature of the DuoMAG software enables the researcher to calibrate both of these responses, and record active motor threshold values, while displaying a colour-coded target value for the participant.


External communications supported via TTL in/out triggers and USB.


The DuoMAG XT rTMS system offers seamless integration through the whole family of Deymed products for true multimodal research studies. Deymed EEG, EMG/MEP systems can control intensity and triggering of TMS devices enabling the user to maintain focus and attention on the participant, rather than the hardware.


Three different repetitive stimulator options and two different cart options enable us to specify a system to any budget or requirement. Standalone systems can be used for desktop workspaces, a cart enables the system to be mounted on a trolley and be portable for use in different sites and an optional counterbalanced electromagnetically operated arm can be specified to ensure coil movement is eliminated in a session. This flexibility, coupled with a wide range of coil types makes the DuoMAG systems unrivalled in terms of their customisation.


The DuoMAG XT rTMS system is a CE-certified medical device for non-invasive brain stimulation in humans. It is limited to investigational and research use in the USA.
