【摘要】 将Ｐｅｌｅｇ的双毯法和Ｎｉｒｕｐａｍ的分维计算法推广应用于肝脏超声图像分维的计算，并对算例结果进行了分析讨论．在此基础上提出了多重分形谱α～ｆ（α）的新分析方法，即用测度族支集的Ｈａｕｓｄｏｒｆ维数ｆ（ｑ）描述超声图像的复杂分形在生长过程中不同层次的特征．将α～ｆ（α）多重分形谱作为超声组织纹理分析的新参数，为组织病变的分类和识别提供了更有效的途径更多还原

【Abstract】 The Peleg′s two blanket method and Nirupam′s fractal dimension method are applied to calculate the liver ultrasonic image fractal dimension. An analysis method is presented for the multi fractal spectrum α～f(α) . It uses a series of partition Hausdorff dimension f(q) to describe the sophisticated fractal characteristics of the ultrasonic images for the different layers during the growing process. The multifractal spectrum α～f(α) is an improvement for recognizing of the tissue diseases.更多还原
