In　this　paper　we　propose　the　way　to　form　a　kind　of　medicine　Image　information　sharing　platform,　which　is　based　on　PACS　and　broadband　network.　And　we　also　discuss　some　key　technologies　used　in　building　up　the　platform,　such　as　sharing　information　between　heterogeneous　data　sources　based　on　HL7,　storing　and　transmission　the　medical　images　based　on　DICOM.　The　study　result　shows　that　it　can　make　full　use　of　those　heterogeneous　data　resources　currently　in　different　hospitals,　and　give　them　a　good　way　to　share　the　data.
