A non-invasive cardiovascular image matching method is revealed. First, a scanning unit scans a heart/blood vessel to get an image of the heart/blood vessel and sends the image to a computer. Then the computer constructs a first 3D model of the heart/blood vessel according to the image of the heart/blood vessel. Next the computer simulates systole and diastole of the heart/blood vessel according to the first 3D model. Later a measured systolic/diastolic change is compared with the simulated systolic/diastolic change by the computer so as to learn systolic/diastolic changes between the heart/blood vessel at this stage and the heart/blood vessel in normal condition.本發明係為一種非侵入式心血管狀態之比對方法，首先，使用一掃描單元掃描一心臟血管而取得一心臟血管影像並傳送至一電腦裝置，之後，使用該電腦裝置依據該心臟血管之影像建構該心臟血管之一第一立體模型，接著，使用該電腦裝置依據該第一立體模型模擬該心臟血管之收縮舒張，之後，使用該電腦裝置依據該模擬收縮舒張變化量比對該心臟血管之一收縮舒張變化量，以取得心臟血管之現階段狀態下與非疾病狀態下之差異。
