Ultrasound image enhancement: A review

SHC Ortiz, T Chiu, MD Fox - Biomedical Signal Processing and Control, 2012 - Elsevier
Medical ultrasound imaging uses pulsed acoustic waves that are transmitted and received
by a hand-held transducer. This is a mature technology that it is widely used around the …

Nonlocal means-based speckle filtering for ultrasound images

P Coupé, P Hellier, C Kervrann… - IEEE transactions on …, 2009 - ieeexplore.ieee.org
