Abstract
A biomagnetometer includes a dewar vessel having a helmet-shaped recess at the lower end of its body. The recess is angled at about 45 degrees to the dewar body axis of the dewar vessel. Biomagnetic sensors are positioned within the interior of the dewar vessel body around the periphery of the recess. The angled recess permits the biomagnetometer to be used with subjects whose heads are inclined from 0 to 90 degrees to the horizontal by pivoting the dewar vessel over an angle of from -45 degrees to +45 degrees to the vertical, without spilling the cryogenic fluid within the dewar or causing excessive evaporation of the cryogenic fluid.
