X-RAY EQUIPMENT FOR TOMOSYNTHESIS

摘要

X-ray equipment for tomosynthesis has two pilot bearings in the form of opposite vertical pillars having common vertical symmetry plane; carriage placed on said pillars with possibility of adjustable reciprocal movement; arcwise rails, which are oppositely fixed onto said carriages and circumscribe an area of placement of examined patients, a controllable collimated X-ray emitter and a digital X-ray receiver, which are oppositely positioned onto said arcwise rails with possibility of controllable unidirectional synchronous angular movement and equipped with facilities for positional checking of theirs; a control unit; a data processing unit, and a tomosynthesis unit. This equipment characterized in that an optical axis of exit aperture of said X-ray emitter (and, in operative position, geometrical axis of X-ray beam) is always perpendicular to the said X-ray receiver surface.
