Wavefront Reconstruction of Breast Microwave Imagery Acquired along Circular Scan Trajectories: A Study on Experimental Feasibility

摘要

In recent years, the use radar technology has been proposed in a wide range of subsurface imaging applications. Traditionally, linear scan trajectories are used to acquire data in most subsurface radar applications. However, novel applications, such as breast microwave imaging, require the use of non linear scan trajectories in order to adjust to the geometry of the scanned area. In this paper the experimental feasibility of a 2D wavefront reconstruction algorithm for subsurface radar data acquired along circular scan trajectories is assessed. The proposed algorithm was successfully tested using data collected from phantoms that mimic the dielectric properties contrast present in an average breast microwave imaging scenario, yielding promising results.
