【摘要】 采用KF—200型X线机作胸部亚高千伏摄影共1500例,效果甚好。经与常千伏摄影对照,亚高千伏图像的密度平均值更接近于X线信息量最灵敏的诊断密度区,在显示胸部重要结构与病变方面,亚高千伏都明显优于常千伏(P<0.01)。作者认为,亚高千伏摄影简便而实用,不失为提高低电压设备胸部成像质量的有效方法。更多还原

【Abstract】 The effect of 1500 chests photographed nnder the conditions of the sub-high KV with KF-200 type X-ray set is good. Compared with the ordinary KV photograph, the average density value of the picture of sub-high KV is moer close to the most siensibly diagnostical density area of the informational capacity of X--ray The sub-high KV is abviously more excellent than the ordinovry KV in shousing the important structure and patholngic change of the chest Authors think the subhigh KV photog raph is simple and usoful It is an effective way to heighten the guaelty of tae chest photograph in tow voetage eguipment更多还原
