Abstract
The technology provides a system and method for simulating and detecting bio signals such as brain bio-signals. Optical fibers provide modulated signals received from an optical signal modulator. The modulated signals are received by a set of emission elements disposed within the phantom body, which output corresponding electrical signals. The electrical signals are detected by a set of sensors and evaluated by a receiver device, such as for an electroencephalograph (EEG), electrocardiogram (ECG), electromyogram (EMG) or magnetoencephalography (MEG) diagnostic system. A controller manages the modulation of light signals so that specific electrical signals can be generated as desired. Because tens, hundreds or thousands of emission elements may be arranged in the phantom body, the controller can manage operation of the optical signal modulator so that the precise physical location of each emission element can be mapped quickly and efficiently. The controller may also detect defective components in a similar manner.
