为了贯彻预防为主的医疗方针,对矽肺能够及早的诊断,我们曾使用高千伏胸部摄片对早期矽肺诊断进行探索。现将其内容和初步认识作如下简单的介绍。高千伏摄片按目前的条件说是指使用100千伏以上的摄片,近代的大型X线诊断机的规格,最高可达150千伏,而通常的高千伏摄片即大约在120～130千伏。高千伏X线的特性在于其波长比低千伏X线更短,穿透力更强。由于其穿透力强,所以它能够通过较厚的组织,到达X片的有效X线要比低千伏X线多。同一部位摄片高
In order to carry out the principle of prevention-oriented medical treatment, for the early diagnosis of silicosis, we have used high kV chest radiography to explore the diagnosis of early silicosis. Now its content and preliminary understanding of the following brief introduction. According to the current conditions, the high-kv radiography refers to the use of radiographs of over 100 kv. The specifications of modern large-scale x-ray diagnostic radiographs can reach up to 150 kilovolts, while the usual high-kv radiographs are about 120 ~ 130 kV. High kilovolt X-ray is characterized by its wavelength shorter than the kilovolt X-ray, penetrating power stronger. Due to its strong penetrating power, it can pass through thicker tissue and reach more effective X-rays than low kV X-rays. The same section of the camera high
