Abstract :
Fractal dimension has been widely used in the process of medical images measurement and analysis. A novel fractal dimension based on triangular prism surface area (TPSA), is introduced to two-dimensional medical images in this article. A series of tests show that this method is accurate and robust in operation. Applying the TPSA method to analyzing the feature characteristics of brain MRI images, tests show that: compared with the normal brain MRI images, fractal dimensions of the abnormal brain images become less. As a result, it is suggested that fractal dimension be one of guidelines in diagnosing some brain diseases
