Abstract
In an embodiment, a neuroimager alignment and coupling evaluation (NACE) system, includes a neuroimaging device; a fiducial affixed to the neuroimaging device; an imaging device; and an augmented reality (AR) module coupled to the imaging device and configured to provide alignment data for the neuroimaging device by tracking facial or cranial landmarks and the fiducial.

receive signal data from the neuroimaging device;
determine a measurement of a quality of the signal data; and
provide the measurement of the quality of the signal data to the user interface.
