...We recently demonstrated that an actuator-assisted translation of the regular λ-pitch linear array by sub-λ distances and creating an augmented denser matrix of raw ultrasound radiofrequency (RF) data resulted in improved resolution and contrast in the reconstructed PAT images from a low-cost PLDbased PAT imaging system [45], [46]....
