Abstract:
An apparatus for suppressing intracranial vibration comprising:means for sensing an intracranial vibrational signal induced within a patient's head, the intracranial vibrational signal including a vibration signal and a noise signal; means for adaptively generating an intracranial vibrational suppression signal as a function of time using only the intracranial vibrational signal from the patient's head as an input, the means for adaptively generating including: means for estimating the noise signal from the intracranial vibrational signal, means for inverting the intracranial vibrational signal, means for combining the estimated noise signal with the inverted intracranial vibrational signal to generate an inverted vibration signal, and means for using the inverted vibration signal as the intracranial vibrational suppression signal; and means for applying the intracranial vibrational suppression signal to the patient's head for suppressing the intracranial vibrational signal.
