Title:
【発明の名称】X線イメージング装置における屈曲光コリメータレンズの焦点合せ装置
Document Type and Number:
Japanese Patent JP2915221
Kind Code:
B2
Abstract:
A focusing apparatus (10) is provided for facilitating the adjustment of the focus for a fixed optics, folded collimating lens (11) in an X-ray imaging system. An idler member (51) is gear driven by an adjustment knob (58), and is threaded to receive a mating threaded portion (35) of the collimating lens (11). The collimating lens (11) is constrained from rotating by set screws (60) on horizontal arms which bear on a stationary bushing (61). Rotation of the adjustment knob (58) thereby causes rotation of the idler member (51) while the collimating lens (11) is restrained from rotating. This results in straight vertical movement of the collimating lens, up or down, until optimum focus is achieved. The set screws (60) also provide for fine rotational alignment of the collimating lens with an image head.
