Abstract

Open ultrasound platforms foster the development of novel image processing techniques due to its flexibility in terms of both software and hardware updates. There is a growing need for rapid prototyping and modelling platforms can be used to develop high-level applications, such as MATLAB/Simulink. Although there are several model-based methods for ultrasound imaging described in the literature, most of them focus on specific digital signal processing stages, and there is little assessment of the simulation environment of Model Composer and System Generator for Xilinx Field-programmable Gate Arrays (FPGA). The purpose of this article is to implement the steps of an ultrasound reception beamforming using the delay and sum technique for B-mode imaging, and then comparing the results between a reference MATLAB script and the results from Xilinx based-model implemented in Simulink environment. The simulation uses 12-bit ultrasound data sampled at 40 MHz from a phantom acquired with a 128-element transducer with an aperture of 8 elements. The design was synthesized for a Xilinx Zynq 7000 FPGA. The qualitative results of the generated B-mode imagens are in excellent agreement, with a CNR error of 0.01, and a processed envelope with NRMSE of 0.085%. In conclusion, the use of tools such as Model Composer and system generator proved to be adequate for rapid prototyping and yields very accurate results for FPGA simulations when compared to MATLAB calculations.
