Curie兄弟(1880)最早发现超声波。根据声波反射原理,用以探测水下障碍物,海中鱼群及金属中的隐性裂隙,曾在工业和军事上发挥了重要作用。至廿世纪四十年代,人们利用超声的生物效应,将其作为一种治疗工具引用于医学。Dussik(1942)首先报告超声可以用于诊断,并记录了头颅超声图。Ludwing和Struthers(1949)用超声检查出胆结石和组织内异物。后来又发现超声可以诊断头部、乳腺、心脏、肝、脾、肾等脏器的各种疾病。五十年代中期,Donald开始将超声诊断应用于妇产科。实践表明超
Curie brothers (1880) found the earliest ultrasound. Based on the principle of acoustic reflection, the detection of underwater obstacles, hidden fissures in fish and metals in the sea, played an important industrial and military role. By the 1940s, people took advantage of the biological effects of ultrasound to refer to medicine as a treatment tool. Dussik (1942) first reported that ultrasound can be used for diagnosis and recorded cranial ultrasound images. Ludwing and Struthers (1949) used ultrasonography to detect gallstones and foreign tissue. Later found that ultrasound can diagnose the head, breast, heart, liver, spleen, kidney and other organs of various diseases. In the mid-1950s, Donald began applying ultrasound to obstetrics and gynecology. Practice shows that super
