Second-harmonic aberration correction

Kaupang, H; Varslot, Trond; Masoy, Svein-Erik


A simulation study is performed to present results concerning 3D aberration correction for harmonic imaging. Two different correction schemes (a pure time-delay correction and a time-delay and amplitude correction) are employed along with estimation based on either the received first- or second-harmonic frequency. An aberrating body wall is implemented as a 20 mm delay-screen body wall using eight screens, and is tuned to match human abdominal wall characteristics. The transmit pressure of the...[Show more]
