An intelligent data encoding algorithm to control high voltage multiplexers for multi-channel medical ultrasound applications is validated in this paper. The time interleaving scanning sequence is controlled spatially on the ultrasound transducer elements to avoid the strong interference caused by the excitation of neighbor elements. The output noise of multiplexer which is designed to enable 32-channel ultrasound scanner mapped with a 128-element linear probe is measured to quantify the interference. The experimental results have shown the leakage at the outputs of multiplexer due to the excitation of neighboring elements is negligible by adoption of the proposed encoding scheme.
