Ultrasonic diagnosis is superior in terms of convenience and minimal invasiveness; therefore, its use has become widespread irrespective of the disease or age group, and unique diagnostic systems have emerged in each field. Ultrasonic diagnosis, which was once the exclusive patent of a single doctor, has also become widespread among laboratory technicians as diagnostic systems advance, and it has enabled remote real-time ultrasonic diagnosis. Thus, use of ultrasonic diagnosis may spread more and more in the future, beyond occupational categories and areas. On the other hand, in the process of sharing ultrasonic diagnosis, we encounter various differences in imaging methods, measurement methods, and reference ranges, etc. In recent years, in the era in which various fields have fused in an interdisciplinary, inter-institutional, and occupational manner, it is undeniable that it is necessary to aim for a certain standardization in ultrasonic diagnosis that has been developed independently. In this paper, we present problems and countermeasures discussed at the symposium on standardization of ultrasonic diagnosis between generations, institutions, and occupations, in the hope that it will serve as a resource for future standardization of ultrasonic diagnosis.
