诊断矽肺,X线照片是极重要的一环,它直接影响矽肺诊断的准确性。因此,如何照出质量高的矽肺片,是值得重视的问题。最近,我们对有粉尘接触史的173例战士,作了胸部平片检查,获得初步成功。现就实际工作中的一些肤浅的体会,作一介绍,供同志们参考。(一)摄片技术:1.曝光条件的计算和运用:这是摄片技术中关键性的问题。条件包括:管电流、曝光时间、管电压和焦片距离四个因素。我们在实际工作中体会到,选择仟伏时,除应考虑到被检者的体厚、肌肉发达情况、软片的感光速度、增感屏的质量外,还
Diagnosis of silicosis, X-ray is a very important part of it directly affects the accuracy of silicosis diagnosis. Therefore, how to take out high-quality silicosis tablets is a problem worth attention. Recently, we conducted a plain film examination of 173 cases of soldiers with dust exposure history and obtained initial success. I now give some introductory remarks on some superficial experiences in practical work for your reference. (A) photographic technology: 1. Exposure conditions of the calculation and use: This is a key issue in photographic technology. Conditions include: tube current, exposure time, tube voltage and focal length of four factors. In actual work, we realize that in selecting a thousand volts, in addition to taking into consideration the body thickness and muscle condition of the subject, the speed of the film, the quality of the sensory screen,
