Abstract
In this paper, the correlation-based ultrasound imaging method called Excitelet is used in conjunction with a new Phase Coherence (PC) metric for medical imaging applications. In this shown that improved lateral resolution and a reduction of imaging artifacts are obtained when compared with Synthetic Aperture Focusing Technique (SAFT). Moreover, the phase content of the reflectivity map can be overlaid to the ultrasound image and allows distinguishing reflectors with different mechanical properties. This novel approach shows great potential for the imaging of specular reflectors and is supported with numerical and experimental imaging results.
