Density correction of peripheral breast tissue on digital mammograms.

Classification of Breast Density in Digital Mammograms

In this paper we investigate a new approach to the classification of mammo graphic images according to breast type based on the underlying texture contained within the breast tissue. Three methods for quantifying the texture are considered and used as input in the evaluation of four different classifiers. In this study we examine two classification tasks, a three-class classification problem be...

Is there an influence of dietary habits on breast density as seen on digital mammograms?

The purpose of this study was to evaluate the influence of dietary habit on breast density, which is an important risk factor for breast cancer. This cross-sectional study was performed on 64 Malaysian women of all races between the age of 35 to 70 years. All subjects underwent mammography and the breast density was analyzed from the images using BI-RADS by two independent radiologists. A vali...

Study of the Effect of Breast Tissue Density on Detection of Masses in Mammograms

One of the parameters that are usually stored for mammograms is the BI-RADS density, which gives an idea of the breast tissue composition. In this work, we study the effect of BI-RADS density in our ongoing project for developing an image-based CAD system to detect masses in mammograms. This system consists of two stages. First, a blind feature extraction is performed for regions of interest (R...

Dosimetric Study of Tissue Heterogeneity Correction for Breast Conformal Radiotherapy

Introduction: Heterogeneity correction is an important parameter in dose calculation for cancer patients where it may be cause inaccuracy in dose calculation as a result of different densities of patients. This study studied the impact of dose calculation of breast cancer patients with and without heterogeneity correction. Material and Methods: Twenty breast cancer patients were treated with Th...
