Abstract: A method and system for automated detection of lesions such as masses and/or parenchymal distortions in medical images such as mammograms. Dense regions and subcutaneous fat regions (102) within a mammogram (100) are segmented (101). A background correction may be performed within the dense regions. Hough spectrum within ROIs (104) placed in the breast region of a mammogram (100) are calculated and thresholded (106) using the intensity value eta in order to increase sensitivity and reduce the number of false-positive detections. Lesions are detected based on the thresholded Hough spectra. The thresholded Hough spectra are also used to differentiate between benign and malignant masses.
Abstract translation: 一种自动检测诸如乳房X线照片之类的医学图像中的诸如肿块和/或实质变形之类的病变的方法和系统。 乳房X线照片（100）内的密集区域和皮下脂肪区域（102）被分段（101）。 可以在密集区域内执行背景校正。 为了增加灵敏度并减少假阳性检测的次数，计算并且使用强度值eta对阈值（106）放置在乳房X线照片（100）的乳房区域内的ROI（104）内的霍夫谱进行阈值处理。 根据阈值霍夫谱检测病变。 阈值霍夫谱也用于区分良性和恶性肿块。

Abstract: A method and system for the automated detection of lesions such as masses and/or tissue (parenchymal) distortions in medical images such as mammograms. Dense regions and subcutaneous fat regions within a mammogram are segmented. A background correction may be performed within the dense regions. Hough spectrum within ROIs placed in the breast region of a mammogram are calculated and thresholded using the intensity value eta in order to increase sensitivity and reduce the number of false-positive detections.
