METHOD FOR AUTOMATIC BREAST DENSITY MEASUREMENT ON DIGITAL MAMMOGRAM

摘要

PURPOSE: A method for automatically measuring breast density is provided to early diagnose a breast cancer by measuring breast density using the intensity of a boundary and an observer model. CONSTITUTION: A histogram is generated according to a pixel value of a breast region(S1). A profile of mean and dispersion is generated as a probability medium variable of the breast region(S2). A boundary intensity profile of the fat region and a mammary duct region(S3). The fat region and the mammary duct region are optimally separated by calculating separability(S4). The density of the breast is calculated(S5).
