Digital Coding Launched Its Realization

The paper probe into the realization of digital-coding emission of B-mode Ultrasound Scanner(BMUS) . The work is based on in-deep study about theory of BMUS and circuit theory. We design a project for digital-coding emission and realize it by technology of FPGA on one circuit board of the fore-end part of BMUS. The project convert the fore-end of BMUS into digital circuit mostly,and make some innovation at the same time. First, the paper discusses the technology of pulse echo BMUS, then give some design of ours. The project is leading of technology, easy for upgrading, strong for extending. It will make large merit in using.
