Abstract

Ultrasound medical imaging continues to progress and allows practitioners to have a fundamental tool to make a good diagnosis and be able to take the best decisions for different medical fields and contributes to the improvement of the medical examination of different diseases. Researchers continue to develop approaches to improve the quality of the ultrasound image. Images generated by the ultrasound system requires high spatial resolutions for a better detection of the organs boundaries. However, images generated by the system suffers from artefacts (e.g. side lobs, grate lobs. etc) which negatively impact the quality of the ultrasound image. Several approaches have been proposed to enhance the spatial resolutions; however, their performances differ depending on the degree of artefacts. In this paper we present three methods of beamforming which has a serious role in the process of US image generation. The first one concern delay-and-sum (DAS) algorithm which is the most commonly used as beamformer , the second is an extension of DAS (DMAS: Delay Multiply and Sum) and the last one is MVB ( Minimum Variance Beamforming) technic. the results show the difference between the three beamforming methods. We try in this work to identify thehiglights and limits of each of these methods.
