Abstract
Abstract Echo-encephalographic apparatus for location of the centerline of the brain relatively to the centerline of the head including a sonic pulse transducer adapted to be applied to one side of the head and a sonic pulse generator connected thereto for providing a sonic pulse for producing echoes from the opposite side of the head and from the centerline of the brain. A computer is connected to the transducer for automatically computing the displacement of the centerline of the brain relatively to the centerline of the head. The computer includes head dimesion measuring means including head dimension gate means for masking preliminary echoes, head dimension centerline calculating means for calculating the centerline of the head dimension, brain centerline measuring means connected to the head dimension measuring means and responsive to a successful head measurement. The brain centerline measuring means includes brain centerline gate means connected to the head dimension centerline calculating means and responsive to echoes within a predetermined displacement of the centerline of said dimension of the head and displacement calculating means connected to the head dimension and brain centerline measuring means providing a displacement signal and including display means for displaying the displacement. The head dimension measuring means includes head measurement signal means for signalling a successful measurement of the head and the brain centerline measuring means includes brain centerline signal means for signalling a successful measurement of the distance to the centerline of the brain.
