Coherent Multi-Transducer Ultrasound Imaging [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2019 An extended aperture has the potential to greatly improve ultrasound imaging performance. This work extends the effective aperture size by coherently compounding the received radio frequency data from multiple transducers. A framework is developed in which an ultrasound imaging system consisting of $N$ synchronized matrix arrays, each with partly ...
