I have been to the industrial building in Ikebukuro today because there was an invitation to attend the abdominal ultrasound seminar. It seemed that 56 people gathered and most of them were young engineers and they participated to hone their skills. 3~4 senior citizens who seem to be a doctor also participated, I was one of them and I took class by the express train in the morning because I wanted to learn recent technical level. Ultrasound examination of the pancreas was difficult, and it was difficult for the engineers also for me to visualize the whole pancreas, but in today's lecture there are many photographs that deliberately depicted the whole image. I thought that we should make every effort to visualize the whole body, not to think as pancreas is difficult. They also expressed brilliantly other liver, gall bladder, or urological organ, I thought that we should follow their superior teacher.
