我科自去年初引进美国费莎425/525HF数字化高频发生器的联动式胸部摄影机ACS1000后,全面开展胸部高千伏摄影,改变了我们(?)直习惯沿用的低千伏胸部摄影观念,同时给我们的临床诊断带来更多的信息量,减少误诊的机会。本文将高千伏摄影与常规低千伏摄影从影像学的角度进行分析比较,肯定了高千伏摄影的特性和优点。 常规摄影是把曝光后的X线胶片经暗房换片经冲洗系统后才得到成像的X线影像征,而联动式摄影系统则是曝光系统和冲洗系统联成一体,免去暗房换片冲洗的程序。曝光后的X光胶片直接转入自动冲洗系统得到成像的X线影像
Since the beginning of last year, our department introduced the United States Fraser 425 / 525HF digitized high-frequency generator linked chest type camera ACS1000, the full chest high kV photography, changed us (?) Straight used low kV chest imaging concept, At the same time to our clinical diagnosis to bring more information to reduce the chance of misdiagnosis. In this paper, high kV imaging and conventional low kV photography from the perspective of imaging analysis and comparison, affirmed the characteristics and advantages of high kV photography. Conventional photography is to expose the X-ray film by the dark room for the film after washing the system to obtain imaging X-ray sign, and linkage photography system is the exposure system and the flush system together, eliminating the need for dark room for film washing program. Exposure to the X-ray film directly into the automatic washing system to obtain the imaging X-ray images
