我国超声成象技术的研究开始于六十年代初期.当时均用我国自己研制或生产的仪器.直到六十年代末期,才从日本引进少量手动接触式复合B型双稳态超声成象仪.如AlokaSSD-3、Aloka SSD-60B和东芝SSL-31A等.1973年北京从西德西门子公司进口一台Vido-son 635机械型快速扫描成象仪.这是进口的
The research on ultrasonic imaging in our country began in the early 1960s when all of them were developed or produced by ourselves in our country.It was not until the late 1960s that a small amount of manual contact composite B-type bistable ultrasound imager was introduced from Japan. Such as Aloka SSD-3, Aloka SSD-60B and Toshiba SSL-31A, etc. In 1973 Beijing imported a Vido-son 635 mechanical rapid scanning imager from Siemens Ltd. This was imported
