A kind of single bony areas separation method,Include the following steps: a) obtaining 3-dimensional image data: carrying out tomoscan using to be scanned position of the scanner to a patient,The plural bidimensional image of acquirement is used,And store the equal bidimensional images in one data bank of what,There are plural tissue points in the equal bidimensional images,And the grade bidimensional images stack to form a 3-dimensional image data； B) bony areas growth and acquisition: bony areas growth,It is that the tissue points are set in the what 3-dimensional image as a starting seed point,Resetting an initiation threshold is growth condition,The outside plural new seed point of growing up since the starting seed point,Bony areas growth is completed and one bony areas of formation until no new seed point generates,Continuation is grown up again,When using the targets threshold as growth condition and bony areas growth terminate,Capture a bony areas.一種單一骨骼區域分離方法，包含有下列步驟：a)取得三維影像資料：使用一掃描器對一患者的待掃描部位進行斷層掃描，藉以取得複數二維影像，並將該等二維影像儲存於一資料庫中，該等二維影像中具有複數體素點，且該等二維影像堆疊形成一三維影像資料；b)骨骼區域成長及擷取：一骨骼區域成長，係於該三維影像中設定一該體素點為一起始種子點，再設定一起始閾值為成長條件，從該起始種子點開始向外成長複數新種子點，直到無新種子點產生即完成該骨骼區域成長而形成一骨骼區域，繼續重新成長，直到以該目標閾值為成長條件時而骨骼區域成長結束，擷取一骨骼區域。
