Encoded Total Focusing Method for Improving Data Acquisition Rate
Proceedings of the International Conference on Bioimaging, 2015 Synthetic aperture imaging techniques are capable to obtain high quality images, fully focused in both transmission and reception. However, these techniques require to perform so many emissions as elements in the array to acquire RF data. This requirement decreases acquisition rate and can result in tissue motion artifacts because of the phase
