Detection of Microcalcification in Mammograms Using Wavelet Transform and Fuzzy Shell Clustering

TLDR
The proposed algorithm for detecting microcalcification in mammogram quality enhancement using multirresolution analysis based on the dyadic wavelet transform and microCalcification detection by fuzzy shell clustering and the effectiveness of the proposed algorithm is confirmed by experimental results.
Abstract
Microcalcifications in mammogram have been mainly targeted as a reliable earliest sign of breast cancer and their early detection is vital to improve its prognosis. Since their size is very small and may be easily overlooked by the examining radiologist, computer-based detection output can assist the radiologist to improve the diagnostic accuracy. In this paper, we have proposed an algorithm for detecting microcalcification in mammogram. The proposed microcalcification detection algorithm involves mammogram quality enhancement using multirresolution analysis based on the dyadic wavelet transform and microcalcification detection by fuzzy shell clustering. It may be possible to detect nodular components such as microcalcification accurately by introducing shape information. The effectiveness of the proposed algorithm for microcalcification detection is confirmed by experimental results.

Estimating the Accuracy Level Among Individual Detections in Clustered Microcalcifications

TL;DR: The results showed that there was a strong consistency between the estimated and the actual number of TPs (or FPs) for these detectors, and lesions estimated to be more accurate in detection were shown to have better classification accuracy than those estimates to be less accurate.

Some practical issues of experimental design and data analysis in radiological ROC studies.

TL;DR: The purposes of this paper are to make users of ROC methodology in medical imaging aware of potential problems that should be confronted before an ROC study is begun and to indicate, at least broadly, how those problems may be dealt with, given the present state of the art.

TL;DR: Analysis of 320 cancers found in a screened population between August 1985 and May 1990 revealed 77 cancers that were "missed" at screening mammography, which occurred in women with denser breasts, were less likely to demonstrate malignant microcalcifications, and were more likely to demonstrating a developing opacity as an indication of cancer.

A novel approach to microcalcification detection using fuzzy logic technique

TL;DR: The essential idea of the proposed approach is to apply a fuzzified image of a mammogram to locate the suspicious regions and to interact the fuzzification image with the original image to preserve fidelity.
