摘要：
The effects of tissue/transducer motion and artifacts from adaptive focusing on synthetic receive aperture (SRA) imaging are explored using experiment, simulation, and theory. The impact of these issues on the selection of SRA subaperture geometry is discussed and a technique to address this problem is demonstrated. The results indicate that SRA with phase correction holds promise in improving ultrasonic image quality.
