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...
In ultrafast imaging using pulse compression, the image quality is limited by the bandwidth of the ultrasonic (US) transducer. Thus extending the effective bandwidth of the US transducers could improve the performance of the current US imaging methods. Resolution Enhancement Compression (REC) allows bandwidth enhancement by exciting the ultrasound transducer with frequency and amplitude modulated...
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...
