Dr. John Julian Wild (USA)
|M.D., Ph.D., FAIUM, Head, Physicomedical Institute, Minneapolis
In 1949, Dr. Wild manufactured prototype equipment for A-mode ultrasonography and with this equipment, he succeeded in measuring the thickness of the human colon. This was the first attempt to use ultrasound for biomedical application.
Subsequently, he developed a two-dimensional ultrasound image employing B-mode equipment, for which he has been also recognized as being the first pioneer of medical ultrasonic imaging. The method today is widely used on a variety of occasions including detection and diagnosis of brain tumors and breast cancer. In particular, the breast imaging by this equipment brought about the successful imaging of a tiny 7mm diameter nipple cancer.
