|Abstract||This paper deals with the design of coded-excitation signal for medical ultrasound imaging. In order to design a code sequence that generates an ultrasound signal with good detail resolution and signal-to-noise ratio, both in frequency-dependent and frequency-independent attenuating media, we propose to use a linear Huffman code obtained by an efficiency-driven optimizing procedure. By resorting to computer simulations, we show that this approach is particularly effective and it outperforms other linear coding schemes commonly used in coded-excitation ultrasound imaging.|
