IRRADIATION FIELD-LIMITING APPARATUS, X-RAY-GENERATING UNIT INCLUDING THE IRRADIATION FIELD-LIMITING APPARATUS, AND X-RAY RADIOGRAPHY SYSTEM INCLUDING THE IRRADIATION FIELD-LIMITING APPARATUS

摘要

An irradiation field-limiting apparatus connected to an X-ray-generating apparatus includes a pair of first limiting blades defining a width of an opening through which radiation is to pass; a first opening width-adjusting mechanism including a first opening width-adjusting shaft operable to adjust the width of the opening by moving the pair of first limiting blades toward or away from each other; and a first opening center-adjusting mechanism including a first opening center-adjusting shaft operable to adjust a center position of the opening by moving the pair of first limiting blades in a same direction. The first opening width-adjusting shaft and the first opening center-adjusting shaft are coaxially arranged.
