摘要

Synthetic aperture focusing techniques (SAFT) make the lateral spatial resolution of single-element conventional B-mode imaging more uniform, which leads to an improved spatial resolution and an extended depth of field. SAFT uses signal processing techniques to synthesize a larger aperture by moving a smaller physical aperture. Several SAFT algorithms have been proposed for different transducer geometries. For single-element focused transducer, the virtual point source techniques have proposed, which treats the geometric focus of the transducer as a virtual point source in the image reconstruction process.
