在放射科日常摄片工作中,摆位正确与否对照片诊断质量影响很大。采用目测法定位,操作不便。为了提高工作质量,我们本着因陋就简、自力更生的原则,制成了用指示灯对淮X线中心线的装置。经一年多的实践,证明制作方法简单,摆位迅速正确。现将制作方法,介绍如下: 一、原理:利用灯光投影,使光线通过两条互成90°角的细裂隙,构成一个十字形影象,十字的交叉点就是X线中心线通过处。二、材料:220伏变6～8伏降压变压器1个;6～8伏指示灯泡2个;与X线遮光筒出口大小相等的圆形胶木板1块;小铆钉4只;8～10厘米长粗铁丝2根;电源线。三、制作:在圆形胶合板上以圆心为中心分割
In the radiological routine photo work, the right or wrong position on the quality of photo diagnosis has a great impact. Positioning using visual method, the operation inconvenience. In order to improve the quality of our work, we made the installation of the center line of Huai X-ray line with indicator light in the principle of simplicity and self-reliance. After more than a year of practice, that the production method is simple, quickly and correctly set. Now the production methods, introduced as follows: First, the principle: the use of light projection, so that light through the two 90 ° angle of the fine cracks forming a cross-shaped image, the intersection of the cross is the X-ray centerline through. Second, the material: a 220V transformer 6 ~ 8V step-down transformer; 6 ~ 8V light bulbs 2; and X-ray tube export the same size of a circular bakelite; small rivets 4; 8 ~ 10 Cm long thick wire 2; power cord. Third, the production: In the circular plywood to center as the center segment
