黑白密度计是对各类射线摄片结果进行客观评定中必不可少的专用测试仪器。在放射摄片中,应用密度计对透射的X片结果进行客观评定,比之用眼睛判别,除具有定量测定不可比拟的优点外,尚能根据对透射的X片评定的结果,进行最佳的曝光条件(mAs.kV)选择,从而使摄片清晰,有助于临床诊断。上海交通大学科技人员,依靠自己技术优势,研制了全新的TD-210型透射式黑白密度计,该仪器技术指标不低于国外同类产
Black and white density meter is the result of various types of radiological assessment of the objective assessment of the indispensable special test equipment. In radiography, the densitometer objective evaluation of the results of the X-ray transmission, compared with the eyes to determine, in addition to the advantages of quantitative determination can not be compared, but also based on the results of X-ray transmission evaluation, the best Exposure conditions (mAs.kV) choice, so that the film clear, to help clinical diagnosis. Shanghai Jiao Tong University, science and technology personnel, relying on their own technological advantages, developed a new TD-210 transmission type black and white density meter, the instrument technical indicators of not less than the same type of foreign production
