Increasing axial resolution of ultrasonic imaging with a joint sparse representation model.

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2016
The axial resolution of ultrasonic imaging is confined by the temporal width of acoustic pulse generated by the transducer, which has a limited bandwidth. Deconvolution can eliminate this effect, and therefore improve the resolution.
