The creation relates to an automatic detection system of vertebral compression fracture, comprising an image processing module for processing an image of computed Tomograph (CT) or Magnetic Resonance Imaging (MRI) and capturing vertebral image and a detection and calculation module for determining three-dimensional margins of the vertebral bones, which determines highest and lowest points of the anterior, posterior, and/or middle vertebral body and calculates vertebral height loss to determine compression fracture degree.本新型係關於一種脊椎壓迫性骨折之自動檢測系統,其包括:一影像處理模組,將電腦斷層取得的影像作影像處理,截取出單純只有脊椎的圖檔;及一脊椎椎體三維邊界偵測及計算模組,測定椎體前、中、後的高點與低點,接著將前後或兩側與中央比較計算椎體高度流失率以判定壓迫性骨折程度。1‧‧‧影像處理模組2‧‧‧脊椎椎體三維邊界偵測及計算模組3‧‧‧資料輸出模組
