3-D microwave imaging of breast tumors with matched-filtering.
Matched-filtering is applied to an algorithm similar to confocal microwave imaging of the breast in order to better detect tumors in a 3-D FDTD model. Strongly scattering objects detected by the imaging algorithm are examined for tumor existence through matched-filtering. Based on the matched-filtering examination, early-time clutter is well suppressed by this method. Also, an antenna-array with a spatial resolution of 8.3 mm is shown to be effective in reducing the clutter level for the successful detection of a 5-mm-diameter spherical tumor.
