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 signals. By compressing these signals in reception with a Modified Wiener Filter (MWF), REC boosts the energy of the backscattered echoes in the frequency bands where the transducer operates inefficiently. This technique has been successfully applied on piezoelectric US probes. However, no real study was conducted on Capacitive Micromachined Ultrasonic Transducers (CMUT). This work is focussed on the implementation of the REC on a CMUT probe in order to evaluate the resolution improvement.
