胸腰段侧位摄片,由于胸腹组织间的密度差异,使得胸、腰椎侧位所显示的影像上黑下白,若曝光条件掌握不好,势必会造成该部位显示黑白对比过强,或由于曝光时间过长而造成运动伪影,从而影响诊断质量,甚至造成重摄片,我科今年初新安装一台北京产F99—TAT 500 mA X线机,通过对以往的摄片失误,对胸腰椎投照方法进行了相应的探讨,现总结如下: 一、设备与方法:(一)X线设备与辅助设备:1.北京产500 mA X线机台,峰值电压150 KVP;2.活
Thoracolumbar lateral radiography, due to the density difference between the thoracoabdominal tissue, making the thoracic and lumbar lateral image displayed on the black and white, if the exposure conditions are not good, it is bound to cause the site to display black and white contrast is too strong, Or due to exposure time is too long and cause motion artifacts, thus affecting the quality of diagnosis, or even cause re-shots, our department early this year to install a Beijing-made F99-TAT 500 mA X ray machine, through the past mistakes, Thoracolumbar projection method for the corresponding discussion, are summarized as follows: First, the equipment and methods: (A) X-ray equipment and auxiliary equipment: 1. Beijing 500 mA X-ray machine, the peak voltage of 150 KVP; live
