This ultrasonic moving image filing system compresses the images and doppler sounds from the image output unit for medical use which is the best known type of ultrasonic diagnostic equipment, with an H.264 encoder, first stores the data in an SD card, and then transmits and saves the data into a hospital's image server via an IP network.

Since the images saved on a server can be accessed through mobile terminals iPhone or iPad which have become popular in recent years, as well as through image reading terminals Windows PC or Mac, images can be accessed anywhere in the hospital as required.

Images can be recorded in units of several minutes by adopting H.264 Standard encoder developed by JRC as the image compression method, which is useful in medical fields where movement needs to be observed, such as the circulatory system.
