Staff exposure to pulsed magnetic fields during depression treatment with transcranial magnetic stimulation
Introduction. Transcranial magnetic stimulation or repetitive transcranial magnetic stimulation (TMS/rTMS) are currently used in research and treatments of diseases of the central nervous system, such as recurring depression. Strong electric pulses are used to produce strong pulsed magnetic fields that are directed to the patient's cerebral cortex where the fields induce electric pulses. The pulses may be causing unnecessary exposure of the staff. Method. The MagVenture TMS/rTMS system was investigated, without patient presence, through measurements of magnetic field pulses at varying distances...
