Resumen

Typical ultrasound image beamforming is based on delay and sum of received echoes. Sound speed inhomogeneity, phase aberration and acoustic clutter induce errors in the beamformed signals. Therefore, coherence-based techniques such as Generalized Coherence Factor (GCF) and Short-lag Spatial Coherence (SLSC) have been developed to reduce these errors. GCF has been used as a weighting factor applied to the conventional image (b-mode), and SLSC has been used as a new standalone image. In this study, a new approach for comparison of both techniques is proposed by using GCF and SLSC as weighting factors and standalone images. Image contrast and contrast-to-noise (CNR) were evaluated to analyze the approaches' performance.
