Design of a quadratic filter for contrast - assisted ultrasonic imaging based on 2D gaussian filters
We present a novel design of quadratic filters (QFs) in the frequency domain in order to improve the quality of contrastassisted ultrasound images for medical diagnosis. The QF is designed as a 2D linear-phase filter. In addition, the magnitude is based on the sum of two 2D Gaussian filters. The cen...
