OVERVIEW

In localized breast cancers, the morphology and shape characteristics of the detected masses have been established as factors of great importance in the discrimination between fibroadenomas, cysts and carcinomas, due to inherent anatomical differences directly related to malignancy. Approximately 80—85% of diagnostic information is retrieved from the mammographic appearance of the mass.

This package contains efficient datasets of simple yet effective shape features, employed in the original and multi-scaled spectral representations of the boundary, for the characterization of the mammographic mass. Their analysis consists of (a) the investigation of the original radial distance measurements under the complete spectrum of signal analysis, (b) the application of curve feature extractors of morphological characteristics.

The files also include the full radial-distance and spectral registration of 142 localized masses in mammograms, as well as a set of qualitative features that have been proven as of outmost importance regarding the true pathology in each case. For the construction of the raw material for these datasets, 130 of the 142 MLO mammograms containing a mass were selected by an expert physician for digitization, including a total of 46 benign mass cases and 84 mass malignancies of various types (12 were marked 'unreliable').

The digitized mammograms were subsequently transformed digitally to a resolution of 63 mm (400 dpi) at 8-bit gray level, which is consistent with other typical image databases of digitized mammograms that are used as a reference in similar studies.

Detailed information about the files and the structure of the datasets are available in the manifest file (S2_data_morph_directory.pdf).
