Field II Simulation of Ultrasound Imaging

Using the Field II simulation software, we have implemented dynamically focused ultrasound phased array imaging. This simulation package runs directly within the Field II environment and requires only the main function to operate. Through this implementation, we can simulate the complete ultrasound phased array imaging process with dynamic focusing capabilities. The code models key aspects including transducer element excitation, pulse propagation, beamforming algorithms, and dynamic focus adjustment during reception. This allows researchers to better understand and investigate the principles and applications of ultrasound phased array imaging technology. During the simulation process, users can modify relevant parameters such as transducer geometry, excitation frequency, focal depth, and scanning patterns to observe how different parameters affect imaging quality and resolution. Therefore, this simulation software serves as an excellent tool for both learning and practical experimentation with ultrasound phased array imaging techniques, providing insights into beamforming algorithms and image reconstruction methods.
