Breast image lesion detection system, breast image lesion detection method, breast image lesion detection program, and computer-readable recording medium recording the breast image lesion detection program

摘要

A breast image lesion detection system, a breast image lesion detection method, a breast image lesion detection program, and a computer-readable recording medium on which a breast image lesion detection program is recorded. A model calculation means (22) obtains a normal construction model of a mammary gland that diffuses in a fan shape from the nipple to the greater pectoral muscle for a breast X-ray image. The direction extraction means 23 extracts the direction of the line structure constituting the shape of the shadow in the breast X-ray image using a Gabor filter. The lesion determination unit 24 compares the direction of the mammary gland of the normally constructed model by the model calculation unit 22 and the direction by the direction extraction unit 23 for the region of interest including the disorder of mammary gland construction detected by the preprocessing unit 21. Thus, a feature amount based on the difference is obtained, and it is determined whether the construction is disordered based on the feature amount. [Selection] Figure 3
