New Fractal Methods for Diagnosis of Cancer

We have proposed two new fractal methods that may be helpful in diagnosis of cancer. To reduce computational complexity, 2-D images of tumors are firstly preprocessed following our methods to form 1-D sequences that are subsequently analyzed using Higuchi fractal dimension. The first method, Image Signature’s Fractal Dimension, is based on analysis of 1-D sequence called the signature of the tumour mass contour. The second method, Image Landscapes’ Fractal Dimension, is based on analysis of two 1-D sequences called the horizontal and vertical landscapes. Both methods are easy and quick and we demonstrated that they may be successfully applied in oncology to support pathologist’s diagnosis.
