[Ultrasound is a widely used and accepted diagnostic modality in the United States . There are many considerable differences between the practice of ultrasound in the United States and our country. Well-skilled sonographers are performing the examinations using abundant amounts of documentation. The main role of the physicians (sonologists) is to interpret the image. Radiologists and other physicians who are doing ultrasound are highly motivated to increase steadily the quality and quantity of ultrasound examinations. Their salary is related directly or indirectly to the number of studies performed. The medico-legal aspects of ultrasound (and of other imaging techniques) are also important. The ultrasound division of the Thomas Jefferson University Hospital in Philadelphia is considered to be the world 's largest ultrasound department. It is directed by Professor Barry B. Gold berg. He is widely known as a leading authority in the „ultrasound world" the author of more than 59 monographs and chapters of different textbooks of ultrasound , and also a pioneer of echocardiography. His first publication on ultrasouncl appearecl twenty-four years ago. During my visit in Philadelphia I had a chance to ask him some of my questions concerning present and future of ultrasound. ]
