The image quality provided by current ultrasound (US) scanners can be increased by extending the effective bandwidth of the US transducers. In 2007, a promising technique, called Resolution Enhancement Compression (REC), was proposed. Combining chirp modulated signals in emission and Modified Wiener Filters (MTF) in reception, REC allows bandwidth enhancement by boosting the energy of the emitted/received signal in the frequency bands where the transducer operates inefficiently. In this paper the first implementation of REC on a research ultrasound scanner using a Capacitive Micromachined Ultrasonic Transducer (CMUT) is presented, the objective being to increase the quality of the images obtained using a Coherent Plane Wave Compounding (CPWC) beamforming technique. The experimental results acquired on wire and cyst phantom indicate a clear increase of the image quality in terms of axial/lateral resolution and signal/contrast to noise ratio. This paper thus proves that REC is capable to yield very good results when implemented on broadband ultrasound transducers.
