System Overview

The DuoMAG MP-Quad combines four DuoMAG MP stimulators to provide a fully configurable quadripulse (QPS) monophasic TMS system. This combination allows individual control of the amplitude of all stimulators as well as the capability of setting the inter-stimulus interval (ISI) and delivering the defined quadro-pulse stimulation through a single coil. The Quadripulse functionality allows users to deliver precise sub- and supra-threshold conditioning and test pulses, which is a vital component when studying inter- and intra-cortical inhibition and facilitation. The inter-stimulus interval for the four pulses is adjustable either in the supplied control software or via external control through TTL inputs, offering ultimate flexibility in ISI control. DuoMAG MP-Quad allows users to combine two stimulator pulses into a single pulse, providing a pulse amplitude that equates to 134% of a single DuoMAG MP output. The DuoMAG Quad can also be used with four separate coils to carry out interhemispheric (quadrilateral) stimulation.

DEYMED Technological Advantages

Powerful System Capable to deliver an intensive monophasic pulse with repetition rate up to 0.5 Hz at 100% intensity with single unit, up to 1.0 Hz with MP-Dual.
Counter-balanced Coil Holder The MagTower cart features an innovative counterweight-balanced positioning arm, significantly reducing the effort required to find and secure the placement of DEYMED coils.
Cooled Coil When used with cooled coils, the system can operate all day without overheating, thanks to a liquid-based cooling system and advanced coil design.
Multi-system Integration Integration with DEYMED's TruTrace EMG and TruScan EEG systems enables advanced clinical and research studies. The greatest advantage is that these systems can fully control the stimulator directly from their interface, making examinations significantly easier.
Touchscreen Interface Combined with intuitive software, it assures ease of use. Touchscreen interface built on Windows, allowing tight integration of Brain navigation by third parties.
Custom Protocol Editor Create, save, and execute any rTMS protocol with customizable stimulation intensity. Fully adaptable to your research or clinical needs.

System Features

  • The DuoMAG MP-Quad combines four DuoMAG MP units to provide fully programmable quadripulse stimulation through a single stimulation coil.
  • The DuoMAG MP-Quad can also be used with four separate coils to carry out interhemispheric (quadrilateral) stimulation.
  • By controlling the pulse intervals and power level of each DuoMAG MP, it is possible to provide precise sub- and supra-threshold conditioning and test pulses.
  • The Inter-Stimulus Interval (ISI) for the four pulses is adjustable either in the supplied control software or via external control through TTL inputs.
  • Each DuoMAG MP can be run independently in the Quad control software or as a standalone DuoMAG MP magnetic stimulator.
  • The DuoMAG MP-Quad allows users to combine two stimulator pulses into a single pulse, providing a pulse amplitude that equates to 134% of a single DuoMAG MP output.
