Abstract:
Objective: To investigate a new class of solutions to the isotropic/homogeneous scalar wave equation, which termed limited diffraction beams and realize ultrasonic 3D imaging. Methods: Limited diffraction beams were derived. We performed the study of 3D pulse-echo imaging with limited diffraction array beam. To obtain high frame rate images, a single plane wave pulse (broadband) was transmitted with the arrays. Echoes received with the same arrays were processed with Fourier method to construct 3D images. Results: Compared with traditional pulse-echo imaging, this method has a larger depth of field, high frame rate, and high signal-to-noise ratio. Conclusion: The new method has prospect of high frame rate 3D imaging. In addition, the imaging system based this method is easily implemented and has high quality image.
