Patent number: 11385349Abstract: Systems and methods for ultrasound imaging using a delay-encoded harmonic imaging (“DE-HI”) technique is provided. An ultrasound pulse sequence is coded using temporal delays between ultrasound emissions within a single transmission event. This coded scheme allows for harmonic imaging to be implemented. The temporal time delay-codes are applied temporally to multiple different ultrasound emissions within a single transmission event, rather than spatially across different transmitting elements. The received radio frequency (“RF”) signals undergo a decoding process in the frequency domain to recover the signals, as they would be obtained from standard single emissions, for subsequent compounding. As one specific example, a one-quarter period time delay can be used to encode second harmonic signals from each angle emission during a single multiplane wave (“MW”) transmission event, rather than inverting the polarity of the pulses as in conventional MW imaging.Type: GrantFiled: October 19, 2017Date of Patent: July 12, 2022Assignee: Mayo Foundation for Medical Education and ResearchInventors: Ping Gong, Pengfei Song, Shigao Chen
