Microcalcifications Detection in Digitized Mammographic Images
A method has been developed to detect and analyse microcalcifications in digitized mammographic images. The algorithms presented in this work combine an image preprocessing to denoise the digital image and image treatment techniques to localize and characterize the features of the microcalcifications. Two image denoising methods have been applied to the mammographies, the first one is an adapti...
متن کاملEnhancement of Mammographic Images for Detection of Microcalcifications
A novel approach to image enhancement of digital mammography images is introduced, for more accurate detection of microcalcification clusters. In original mammographic images obtained by X-ray radiography, most of the information is hidden to the human observer. The method is based on redundant discrete wavelet transform due to its good properties: shift invariance and numeric robustness. The p...
متن کاملAnalysis of mammographic microcalcifications using a computationally efficient filter bank
We present a new method for classification of malignant and benign clusters of microcalcifications in digital mammograms. A computationally efficient infinite impulse response (IIR) quadrature mirror filter (QMF) bank is used as a tool for extracting texture and shape features. The filter bank splits the input image into four subbands: low-low band, low-high band, high-low band and highhigh ban...
متن کاملComputerized Image Analysis of Mammographic Microcalcifications: Diagnosis and Prognosis
Breast cancer is the second leading cause of cancer deaths in women today (after lung cancer) and is the most frequently diagnosed cancer among women, excluding skin cancers. According to the American Cancer Society, an estimated of 230,480 new cancer cases are expected to be diagnosed in 2011; about 2,140 new cases are expected in men. In addition to invasive breast cancer, 57,650 new cases of...
متن کاملMRI for the assessment of malignancy in BI-RADS 4 mammographic microcalcifications
PURPOSE Assess the performance of breast MRI to diagnose breast cancer in BI-RADS 4 microcalcifications detected by mammography. MATERIALS AND METHODS This retrospective, IRB-approved study included 248 consecutive contrast-enhanced breast MRI (1.5T, protocol in accordance with EUSOBI recommendations) performed to further diagnose BI-RADS 4 microcalcifications detected at mammography during a...
