摘要:
A method, system, and apparatus for monitoring a magnetic field related to magnetic stimulation may be provided. A system for monitoring a pulsing magnetic field related to magnetic stimulation therapy may include a magnetic stimulation component, a sensor, and a processor. The magnetic stimulation component may be configured to generate the pulsing magnetic field for the magnetic stimulation therapy. The sensor may be configured to generate a signal associated with the pulsing magnetic field. The processor may be configured to estimate a first characteristic associated with a first peak of the signal, estimate a second characteristic associated with a second peak of the signal, and determine a third characteristic of the signal based on the first characteristic and the second characteristic. The processor may be configured to determine whether a failure occurred based on the third characteristic of the signal.
摘要:
A proximity sensor for a transcranial magnetic stimulation (TMS) system detects the proximity of a TMS coil assembly to a position at which the coil is to receive pulses during TMS treatment and provides feedback to the operator so that the operator may adjust the TMS coil assembly to maintain optimal positioning during treatment. A flexible substrate containing a sensor or sensor array is disposed between the TMS coil assembly and the position such that the coupling of the TMS coil assembly to the position may be detected by the sensor(s). Sensor outputs are processed by signal processing circuitry to provide an indication of whether the TMS coil assembly is properly disposed with respect to the position during TMS treatment. A display provides an indication of how to adjust the TMS coil assembly to improve the positioning of the TMS coil assembly.
摘要:
A TMS device may include treatment coils and ferromagnetic components that are configured to be disposed proximate to corresponding ones of the treatment coils. The treatment coils and ferromagnetic components of the TMS device may cooperatively generate a magnetic field that exhibits one or more characteristics that differ from those of a magnetic field that is generated by the treatment coils alone. For example, the magnetic field may exhibit lower induced electrical stimulation intensity in the cranial nerves, while substantially maintaining a penetration depth into the subject's brain. In another example, the magnetic field may exhibit increased penetration depth into the subject's brain, while substantially maintaining induced electrical stimulation intensity in the cranial nerves. The TMS device may be configured to be adjustable and/or reconfigurable, for instance with respect to the anatomy of a subject (e.g., to the shape of the subject's head).
摘要:
The invention is directed to a novel method for reducing discomfort caused by transcutaneous stimulation. The novel method includes providing transcutaneous stimulation, reducing the transcutaneous stimulation at a first location, and substantially maintaining the transcutaneous stimulation at a second location. The transcutaneous stimulation may be created by electric and/or magnetic fields. The first location may be relatively proximate to the cutaneous surface and may comprise tissue, nerves and muscle. Also, the second location may be relatively deeper than the first location and include, for example, brain tissue that requires the transcutaneous stimulation for treatment purposes. The invention further may include locating a conductor on a treatment area and/or a transcutaneous stimulation device relative to the first location. In addition, the method may further include adjusting how much the transcutaneous stimulation is reduced at the first location.
