Description

等中心指示灯的检测器
本实用新型涉及一种利用光学性质检测等中心指示灯是否偏离正常位置的仪器。
在等中心放射治疗中通过等中心激光指示灯确定直线加速器等仪器所要治疗的病灶,俣因经常拔动等中心激光指示灯的开关,使等中心激光指示灯偏离正常位置,那么,由它们确定的等中心点的就偏离了病灶,影响疗效,损坏人体正常组织。
本实用新型的目的在于提供一种操作简便,并能快速、直观和准确地检测等中心指示灯是否偏离正常位置的仪器。
本实用新型的特征在于底座通过转轴与设有透明检测片的框架相连,透明检测片上设有网状刻度,底座上设有水银气泡。
本实用新型由底座和透明检测片组成,结构十分简单;检测时,让三个等中心指示灯照到透明检测片,若某一灯偏离正常位置,则三束光不能交于一点,偏离的光束和偏离距离既可显于透明检测片,然后调节那个发生偏离的指示灯使其光束与另外两束光交于一点,既完成了检测与调节;操作十分方便,而且具有直观、快捷和准确的优点。
以下结合附图对本实用新型予以详述。
图1是本实用新型实施例的结构示意图
参照图1,本实施例包括底座(3)和框架(1),框架(1)通过转轴(4)和底座(3)相连接,框架(1)内设有带网状刻度的透明检测片(5),底座(3)上设有水银气泡(2)。
