Abstract

An X-ray computer tomography system for imaging the internal structure of a human being (30) including a source (22) that projects a substantially conically shaped X-ray beam along a path on to a subject such that at least a portion of the beam is transmitted through the subject and a detector array (34, 38) that detects the portion of the beam transmitted through the subject and operative to generate electronic signals in response to the beam transmitted through the subject that projects on to the detector array. The system also including a patient support structure for supporting the subject and rotating the subject about an axis intersecting with and substantially perpendicular to the path of the beam, wherein the subject is constrained such that the subject remains in the path of the beam and an airbag restraining mechanism attached to the support structure for holding the subject in its position.
