Devices, and methods for measuring bioimpedance signals are disclosed. One aspect may include a headset apparatus including a retainer and electrodes. The retainer may be configured to position the electrodes on the head of a subject so as to obtain bioimpedance signals indicative of hemodynamic conditions associated with an MCA territory. A processor may be included to measure and analyze the obtained bioimpedance signals, and to output information for predicting hemodynamic conditions associated with an MCA territory.

Devices and methods for monitoring cerebral hemodynamic conditions

Devices, and methods for monitoring cerebro-hemodynamic signals are disclosed. In one aspect, the devices and methods may include receiving at least one signal characterizing a bioimpedance measurement. The at least one signal may be correlated with the timing of a cardiac wave and analyzed to ascertain an extent of an expected characteristic within the signal. The extent of the expected characteristic may be used to provide information for predicting a physiological brain condition. The at least one signal may include two signals, obtained from opposite brain hemispheres, and may be a bioimpedance signal.

A method of estimating blood flow in a brain, comprising: a) causing currents to flow inside the head by producing electric fields inside the head; b) measuring at least changes in the electric fields and the currents; c) estimating changes in the blood volume of the head, using the measurements of the electric fields and the currents, where the current are produced in children or using electrodes at or near holes in the skull. Optionally, the configuration is selected to focus the flow of current to be inside the brain to a significant degree.

Device for monitoring blood flow to brain

A method of estimating cerebral blood flow by analyzing IPG and PPG signals of the head, the method comprising:

Cerebral perfusion monitor

A method of estimating at least one intracranial hemodynamic parameter in a subject, the method comprising:

Non-invasive intracranial monitor

A method of estimating cerebral blood flow includes obtaining a measure of time-varying blood volume in the head, using an impedance plethysmography (and), obtaining a measure of time-varying blood volume in the scalp, and using the time-varying blood volume in the head and scalp to estimate cerebral blood flow.

A computerized system for locating a device including a sensor module and a processor. A radioactive source, associated with the device, produces a signal in the form of radioactive disintegrations. The sensor module includes a radiation detector capable of receiving a signal from the source attached to the device. The sensor module produces an output signal. The processor receives output signal(s) and translates output into information relating to a position of source.
