Adjustable helmet for use with optically-pumped magnetometer

Abstract

Helmets are used with neuroimaging machines, such as optically pumped magnetometers (OPMs). The helmets house sensors that are used with the OPMs that are positioned adjacent a participant's head in a way that the machine is able to acquire neural information. The placement and orientation of the sensors is important so that accurate information can be obtained. However, to account for heads of various sizes, especially with children, mechanisms can be provided that allow for movement of portions of the helmet. For example, the helmet can include sections that are movable in multiple directions relative to one another to change the overall size of the helmet to account for varying head sizes, without affecting the efficacy of the helmet and sensors.
