肝脏超声组织定征新参数——多重分形谱

针对肝脏超声图像特征。提出了一个多重分形谱α－ｆ（ａ）的新分析方法，用测度族支集的Ｈａｕｓ－ｄｏｒｆｆ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，并以α－ｆ（ａ）多重分形谱作为组织定征新参数，采用神经网络绎组织病变进行分类和识别，具有明显的实用意义。

New Parameter of Liver Ulitasonic Tissue CharacterizationMultifractal Spectrum

Based on the previous research about the feature of liver ultrasonic images ,this paper presents a new analysis method of multifractal spectrum f().Using a series of partition Hausdorff dimension f(q)this paper describes the sophisticated fractal characteristics of the ultrasonic images in the different section of the growing process and the multifractal spectrum f() acts as the new parameter of the ultrasonic issue characterization. Using the neural network it has catalogued and recognized the tissue diseases, carring out ultrasonic tissue characterization.Apparently,this method has practical significance.
