Abstract：

Analyzing　the　strain　of　blood　vessel　wall　is　the　foundation　to　evaluate　the　elasticity　of　blood　vessel　wall,　and　the　elasticity　of　blood　vessel　wall　is　an　important　reference　to　estimate　the　function　of　cardiovascular　system.　In　this　article,　a　mathematical　model　of　the　strain　was　established　based　on　the　finite　deformation　mechanics　theory　and　intravascular　ultrasound　(IVUS)　images.　And　the　relative　strain　was　calculated.　The　blood　vessel　wall　was　divided　into　many　triangle　grids　and　the　strain　of　blood　vessel　wall　was　calculated　based　on　these　triangle　elements.　The　result　showed　that　the　condition　of　the　strain　was　very　complex.　There　existed　the　positive　strain　(both　in　x-axis　and　y-axis)　and　angular　strain.　The　proposed　method　was　testified　using　the　images　with　known　strain.　It　was　demonstrated　that　the　method　could　distinguish　the　pathologic　region　exactly　and　analyze　the　situation　of　strain,　being　promising　in　evaluating　function　of　artery　and　clinical　diagnosis.
