Abstract
An adjustable collimator for reducing the emission of off-focus radiation and for use in selectively altering the size of an x-ray beam produced by an x-ray tube is disclosed. The collimator comprises a base member supporting a collimator plate that defines a first x-ray passing region. A radiation blocking member is operably attached to a moveable block that is disposed in the base member such that selective movement of the block causes the blocking member to obstruct and thereby reduce the size of the first region and create a smaller-dimensioned second region through which x-rays can pass.
