Abstract
Optical Properties of Non-Malignant and Malignant Breast Tissue Determined by Surface Displacement of Laser-Induced Photoacoustic Generation
Highlights
It has been estimated that one out of every nine women will develop breast cancer during her lifetime and approximately 30% of them will die of the disease [1,2].The beneficial effect of screening mammography has been shown in several studies world-wide where 20%-50% reduction in breast cancer mortality with screening has been demonstrated [3,4,5,6,7,8,9]
While mammography has clearly become the method of choice in the detection of early, clinically occult breast cancer, it has limitations
Of all the breast cancers, only averages of 88% are seen on mammography [12]
Summary
Ultrasonic thermo elastic waves were generated in breast tissue by the absorption of nanosecond laser pulses at 1064 nm produced by a Q-switched Nd: YAG laser in conjunction with an optical interferometer sensor was used to detect the thermo elastic deformation
