    摘要： A system and method for evaluating neural shunt functionality is provided. Accordingly, in one aspect a method for monitoring neural shunt functionality may include measuring a first intracranial pressure pulse inside the shunt, measuring a second intracranial pressure pulse outside the shunt, and comparing pulsatile characteristics from the first measurement to the second measurement in order to determine shunt functionality.

    摘要： Electrical impedance monitoring of a tissue or an organ for perfusion or viability has been limited by sensitivity and baseline shifts. An apparatus and method are described which improve sensitivity by making the intervening tissue between pairs of electrodes a determinant component of electrical resonance. Such sensitivity further enhances detection of the pulsatile component of blood flow within a tissue. Baseline shift can be monitored and compensated due to resonance shift. The method is adaptable to sufficiency of perfusion monitoring or viability, imaging by 2-dimensional or 3-dimensional electrical impedance tomography, monitoring of tissue ablation by thermal or chemical methods, and thermoplasty of tissues to alter their form and functionality.

    摘要： Systems and methods for measuring intracranial pressure and brain compliance are provided. In one aspect, for example, a method for noninvasive measurement of brain compliance in a subject may include calculating a phase shift between an intracranial pulsatile perfusion flow measured from the subject and an extracranial pulsatile perfusion flow measured from the subject, and determining brain compliance of the subject from the phase shift between the intracranial pulsatile perfusion flow and an extracranial pulsatile perfusion flow. Though various methods of calculating phase shift are contemplated, in one aspect such a calculation may include calculating an intracranial frequency waveform corresponding to the intracranial pulsatile perfusion flow, calculating an extracranial frequency waveform corresponding to the extracranial pulsatile perfusion flow, and calculating a phase difference between the intracranial frequency waveform and the extracranial frequency waveform.
