随着数字化X光机的发展,胸部高千伏摄影技术已得到临床广泛认可,而高千伏胸部摄影有着普通摄影条件无法比拟之优势,它不但扩宽了胶片信息量,增加诊断范围,提高胶片影像的分辨率,使照片质量上升到新的层次。而且可减少X线管的热容量,有效地延长球管使用率,且相对减少病人的X线照射剂量。 With the development of digital X-ray machine, chest high-kV photography has been widely recognized in clinical practice, and high-kV chest photography has unmatched advantages of ordinary photography conditions, it not only broadens the amount of information on the film to increase the scope of diagnosis and increase Film image resolution, so that photo quality rose to a new level. But also reduce the heat capacity of the X-ray tube, effectively extend the usage of the bulb, and relatively reduce the dose of the X-ray irradiation of the patient.
