Abstract

Single transmit imaging, formed by scanning the receive beam around a single transmit beam is used to study the characteristics of fundamental and harmonic beams and to evaluate the performance of time-shift compensation as a means of phase aberration correction. The results indicate that the harmonic beam has a greater depth of field compared to the normal beam, and that time-shift compensation can restore the beam pattern using random scattering data under ideal aberration conditions. Results of time-shift compensation using random scattering data also showed significant improvement in image quality on a special phase aberration phantom that contains an aberration layer of extended thickness
