Abstract

An algorithm for correction of both the amplitude attenuation and frequency-shift in B-mode ultrasonic imaging is presented. The algorithm is based on a dynamic one-dimensional finite-impulse-response (FIR) filter. A direct formula for coefficients of the system was derived supposing that the attenuation is linearly dependent on the frequency. Also the approach incorporating the lateral inhomogeneity is described
