The Resolution Enhancement Compression (REC) technique is a coded excitation method developed for improving the axial resolution of ultrasound images. It consists on emitting an amplitude modulated chirp signal that transmits more energy at the frequencies where the ultrasound transducer is less efficient. The focus of this study is to elaborate a new beamforming strategy, which consists of implementing...
One of the objectives in ultrasonic imaging is to improve the spatial resolution of the acquired images. The axial resolution is determined by the transducer bandwidth and the beamforming process. The resolution enhancement compression (REC) technique allows extending the bandwidth by combining the concepts of frequency and amplitude modulated excitation with modified Wiener filter compression.

In the framework of PICMUS challenge, the objective comparison between steered plane waves beamforming is proposed on an external platform. Our beamforming proposal consists in a weighted minimum variance approach which combines a phase coherence factor calculation and a minimum variance beamforming. The computation is made in the IQ domain in order to reduce the calculation effort. An adaptive scheme...
High frame rate imaging became a world-wide use modality. It achieves by coherently coalescing the received radio frequency signal, as low-resolution image, after emitting plane waves. One common way to increase the image quality is to combine multiple low-resolution images, from different insonification angles, into a high-resolution image. However, this compounding technique significantly decrease...
