Phantom

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a 'phantom' device used for calibrating and testing EEG (electroencephalography) and MEG (magnetoencephalography) neuroimaging systems. Unlike traditional phantoms that use electrical connections to create artificial dipoles, this invention employs a non-electrical (optical) triggering system, such as light sources and photodiodes, to generate dipoles within the phantom. This approach eliminates unwanted electromagnetic interference caused by wires and allows for the generation of multiple, precisely controlled dipoles at known locations.
