Purpose:　To　present　a　new　real-time　system　for　acquisition　and　display　of　B-scan　ophthalmic　ultrasound　images.　Method:　Firstly,　the　super　video　graphics　array　(SVGA)　digital　signal　was　acquired　from　the　front-end　of　video　graphics　array　(VGA)　connector　and　then　was　transmitted　to　static　random　access　memory　and　universal　serial　bus　(USB)　chip　controlled　by　field-programmable　gate　array　(FPGA).　Secondly,　the　image-data　(from　SVGA　signal)　were　encoded　to　reduce　errors　during　transmission.　Finally,　the　image-data　were　decoded　by　personal　computer　(PC)　software　to　display　and　process.　Result:　This　system　made　the　B-scan　ultrasound　images　transmit　in　real-time　with　a　speed　of　71　Mb　s(-1)　and　made　the　images　display　clearly.　Conclusion:　This　study　explored　the　feasibility　of　real-time　transmission　and　display　of　B-scan　ultrasound　images　with　USB.　Furthermore,　it　is　indicated　that　digital　video　acquisition　can　transmit　images　with　high　fidelity　and　high　speed,　and　can　make　the　images　easy　to　store　and　process.
