摘要：
A quantification method and an imaging method are disclosed, capable of quantifying the margin feature, the cysts feature, the calcifications feature, the echoic feature and the heterogenesis feature of a tumor, and capable of imaging the margin feature, the cysts feature, the calcifications feature and the heterogenesis feature of a tumor. The quantification method and the imaging method calculate the moving variance of the gray scale of each of the pixel points based on the gradient value of the gray scale of these pixel points. Then, depending on the purpose of the quantification method or the imaging method, the maximum value, the minimum value, the mean value, and the standard deviation of the moving variance of the gray scale of these pixel points are calculated, respectively. At final, with the definition of the threshold value and the imaging rule, the above features of the tumor are quantified or imaged.本發明係關於一種腫瘤特徵的量化方法及影像化方法,尤指一種適用於將腫瘤所具有之邊緣特徵、囊腫特徵、鈣化特徵、迴音性特徵及異質化特徵量化的量化方法及將這些腫瘤特徵影像化之影像化方法。本發明之腫瘤特徵的量化方法及對應之影像化方法係從各像素點所分別具有之灰階梯度值中,計算出各像素點所分別具有的灰階移動變異值。隨後,再依據所欲量化或影像化之腫瘤特徵的不同,計算出這些灰階移動變異值的平均值、標準差、最大值、最小值等。最後,配合不同的閥值或成像標準的設定,將前述之腫瘤特徵分別量化及影像化。該圖為一流程圖故無元件代表符號
