DC-STIMULATOR MR
The DC-STIMULATOR MR is a CE-certified medical device for conducting non-invasive transcranial direct- and alternating current stimulation (tDCS, TACS) on people specifically during magnetic resonance imaging (f)MRI. DC stimulation is used to treat strokes, epilepsy, migraine, tinnitus, depression, multiple sclerosis, dementia and chronic headache.
The DC-STIMULATOR MR is a micro-processor-controlled constant current source. It meets the highest safety standards thanks to (hardware- and software-based) multistage monitoring of the current path. By continuously monitoring electrode impedance it can detect insufficient contact with the skin and automatically terminate stimulation. This is a reliable method of excluding any injury to the patient.
DC-STIMULATOR MR features:
- 1 channel, unipolar (DC) and bipolar (AC) stimulation
- Adjustable range of current ±4,500 µ, maximum adjustable current strength ±3,000 µ (peak-to-peak)*
- Adjustable application time up to 30 minutes *
- Frequencies adjustable up to 250 Hz, phase freely adjustable
- 4 standard modes - single (continuous stimulation) - pulse (cyclical stimulation activation/deactivation) - sinus (sinus wave) - noise (normally distributed)
- Use during fMRI, no interference of the MRI images during EPI sequence
- RF filter module with MRI-compatible cables and electrodes
- customer-specific programs possible (optional)
- "Study mode" for blind processing of genuine and 'pseudo' stimulation (optional)
- External trigger input and output (optional)
