Fractal analysis techniques are common tools in physics and image processing. In the past few years they have gained increasing attention in medical sciences, e.g., cardiology, pathology and radiology, respectively. This article intends to describe this new technique by applying fractal analysis to the instant of a breast carcinoma. One of the advantages of fractal analysis is the ability to describe an irregular and complex object by a measureable value, called the fractal dimension. The fractal dimension can be determined by using the box-counting method. We applied this technique to the mammography as well as to the histologic section of a breast carcinoma. The application of fractal analysis provides a specific measureable value of the growth pattern of a tumor. Thus, the fractal dimension serves in addition to the common used metric diameter.
分形分析技术是物理学和图像处理中的常用工具。在过去几年中，它们在医学领域，如心脏病学、病理学和放射学中受到了越来越多的关注。本文旨在通过将分形分析应用于乳腺癌实例来描述这项新技术。分形分析的优点之一是能够通过一个称为分形维数的可测量值来描述不规则和复杂的物体。分形维数可以通过盒计数法来确定。我们将这项技术应用于乳腺癌的乳腺X线摄影以及组织切片。分形分析的应用提供了肿瘤生长模式的一个特定可测量值。因此，分形维数除了常用的度量直径外还能发挥作用。
