TMS + rTMS transcranial magnetic stimulator DuoMAG® QPS

∙ Programmable quadropulse protocols ∙ Up to 8 Hz repetition rate (2 Hz at maximum output) ∙ Modular configuration ∙ Full range of Deymed Coils System Overview The DuoMAG Quadropulse System (QPS) combines four DuoMAG MP stimulators to provide a fully configurable quadropulse TMS stimulator. This combination allows individual control of the amplitude of all stimulators as well as the capability of setting inter-stimulus interval (ISI) and delivering the defined quadropulse stimulation through a single coil. The quadropulse 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 external control via TTL inputs, offering the ultimate flexibility in ISI control. DuoMAG QPS allows users to combine the two stimulator pulses into a single pulse providing a pulse amplitude that equates to 140% of a single DuoMAG MP output. The DuoMAG QPS can also be used with four separate coils to carryout interhemispheric (quadrolateral) stimulation. System Features The DuoMAG QPS combines four DuoMAG MP units to provide fully programmable quadro-pulse stimulation through a single stimulation coil. The DuoMAG QPS can also be used with four separate coils to carryout interhemispheric (quadrolateral) stimulation. By controlling the pulse intervals and power level of each DuoMAG MP, it is possible to provide precise sub- and supra-treshold conditioningand test pulses.
