Development of a dynamic 4D anthropomorphic breast phantom for contrast-based breast imaging

Conference Progress in Biomedical Optics and Imaging Proceedings of SPIE · May 4, 2012 Mammography is currently the most widely accepted tool for detection and diagnosis of breast cancer. However, the sensitivity of mammography is reduced in women with dense breast tissue due to tissue overlap, which may obscure lesions. Digital breast tomos ... Full text Cite

Optimal Multisensor Decision Fusion of Mine Detection Algorithms

Conference Proceedings of SPIE the International Society for Optical Engineering · November 26, 2003 Numerous detection algorithms, using various sensor modalities, have been developed for the detection of mines in cluttered and noisy backgrounds.

Improved decision-theoretic approach to the optimum detection of mines

Conference Proceedings of SPIE the International Society for Optical Engineering · December 1, 1997 The fundamental goal of mine detection is to achieve a high detection rate along with a low false alarm rate. While many mine detectors achieve the first of these goals, it is often at the cost of a prohibitively large false alarm rate. In this paper, a Ba ... Cite
