1. A head holder for a medical scanner, comprising:
at least one movable component that moves with a head of a patient while the head is placed on the at least one movable component during brain imaging by the medical scanner, and
one or more inertial measurement units attached to the at least one movable component, the one or more inertial measurement units comprising a 3-axis magnetometer for measuring direction of a magnetic field and at least one of a 3-axis gyroscope for detecting angular velocity or a 3-axis accelerometer for detecting direction of a gravitational field, wherein the one or more inertial measurement units measure motion data in the time domain, wherein any change in orientation of the at least one movable component indicated by the motion data represents motion of the head, wherein the one or more inertial measurement units communicate the motion data to a computer system during the brain imaging in substantially real time to record motion parameters.
