1.The captured ultrasonic images are stored into the high-speed disk in AVI file format. The author realized the successive or frame- by-frame playback and some editing functions such as zoom out, zoom in, copy, delete, of the ultrasonic images. Besides, the author achieved the transformation of file format form AVI to BMP, and this will do a great convenience to the later process of edge enhancement and edge outlining and provide the original data for three-dimensional surface reconstruction.
