Abstract
A new approach for the optimal design transversal filter bank for parallel processing of echo data in 3D realtime acoustical imaging is proposed. The approach is based on a discretized linear time-domain formulation of the imaging equation for systems that employ either coded-aperture transducers or transmitter arrays with coded-excitation. The two approaches are mathematically equivalent and result in an imaging system architecture which is based on parallel processing of sampled vector of echo data with a bank of transversal filters. The filter coefficients are obtained through a pseudoinverse operator which is designed to decouple echoes received from different image lines.
