Ultrasound phase aberration correction

WebAbstract—A method of acoustic imaging in a liquid throug h a solid-state lens by using phase data processing with aberration correction is proposed. Results are presented from the theoretical modeling and the experi-mental study of investigating objects located in water. DOI: 10.3103/S1062873821060198 INTRODUCITON WebMedical sonography images are reconstructed with simplifying assumptions on wave propagation, by one of the most important assumptions being that the imaging center is written of a constant sound speed. Once the presumption of a constant sound speed are violated, which lives true in most in vivoor cl …
