Study of circularly symmetrical two-dimensional digital filters possessing separable denominator transfer functions
… objective of this Thesis has been to implement two-dimensional filter functions using simple design procedures and to study the presence of circular symmetry in such designed filters by parameter modifications. In keeping with the simple design criteria, the two-dimensional filters studied in …

Post-beamforming filtering for enhanced contrast resolution in medical ultrasound.
… the use of post-beamforming pseudoinverse filtering algorithms for restoring contrast resolution in pulse-echo medical ultrasound imaging. Limited contrast resolution is probably the single most important limitation of ultrasound compared with leading medical imaging modalities. While …
