Detection of Breast Tumor in Scattered Fibroglandular Breast Tissue Using Inverse Scattering Technique

Abstract

In this paper, Forward-Backward Time-Stepping inverse scattering technique is utilized to detect the presence of malignant tumor in a scattered fibroglandular tissue of the breast. A 2D slice on the coronal plane from the 3D numerical scattered fibroglandular breast phantom is selected. The tumor is added into breast phantom with low contrast between the normal breast and malignant tumor tissue. Through numerous simulations, FBTS technique showed the ability to identify the presence of 6mm in diameter tumor embedded in fibroglandular tissue of the breast at low frequency. As frequency increases, this technique was unable to reconstruct the object under test (OUT) accurately. In order to solve this problem at higher frequency, Frequency-Hopping approach is then applied to integrate with the FBTS technique. The presence of tumor successfully detected and computational time is also reduced.
