(一)概况西门子公司 X 线部生产各种类型的 X 线机和设备,产品配套完整,坚固耐用,在国际市场上具有比较先进的水平。目前该公司生产的 X 线诊断设备,正朝着大功率和自动化方向发展,并大量采用电视、电影和磁带录象等新技术,从而使 X 线动态摄影技术前进了一步,提高了对某些脏器的生理功能和病理改变的 X 线诊断技术。同时为了合理而有效地使用 X 线管和简化操作程序,还采用了 X 线管连续下降负荷的保护装置、曝射剂量的自动控制、体层摄影自动密度调整及程序控制等新方法,这样就提高了 X 线管的使用效能,缩短了曝光时间,并获得满意的 X 线摄影效果。
(A) Overview Siemens X-ray production of various types of X-ray machines and equipment, complete product support, durable, in the international market with more advanced level. At present, the X-ray diagnostic equipment produced by the company is moving toward high-power and automation, and a lot of new technologies such as television, movie and tape video recording are taken to make X-ray dynamic photography a step forward and improve the quality of certain X-ray diagnosis of organ function and pathological changes. At the same time, in order to use the X-ray tube rationally and effectively and to simplify the operation procedure, new methods such as continuous descending load protection of the X-ray tube, automatic exposure dose control, automatic density adjustment of tomography and program control are adopted. X-ray tube to improve the use of performance, shorten the exposure time, and obtain satisfactory X-ray photography.
