Publication number: 20210059644Abstract: Systems and methods for performing ultrasound imaging. Ultrasound information of a subject region in response to ultrasound pulses transmitted toward the subject region can be collected. One or more ultrasound images of at least a portion of the subject region can be formed using the ultrasound information. The ultrasound information can be stored in a memory. In turn, the ultrasound information can be accessed from the memory. Subsequently, the ultrasound information accessed from the memory can be reprocessed to retrospectively generate one or more additional ultrasound images of at least a portion of the subject region.Type: ApplicationFiled: March 10, 2020Publication date: March 4, 2021Inventors: Donglai Liu, Ting-lan Ji, Glen W.

Publication number: 20200219228Abstract: Systems and methods for performing ultrasound imaging. Main channel domain data for performing ultrasound imaging of a subject area for performing ultrasound imaging of the subject area is collected. Further, region of interest (“ROI”) channel domain data for performing ultrasound imaging of a ROI within the subject area is collected. One or more ultrasound images of the subject area can be formed using the main channel domain data. Additionally, one or more ROI ultrasound images of the ROI within the subject can be formed independently from the one or more main ultrasound images of the subject area using the ROI channel domain data of the ROI within the subject area. Subsequently, the one or more ROI ultrasound images can be displayed concurrently with the one or more main ultrasound images.Type: ApplicationFiled: January 8, 2019Publication date: July 9, 2020Inventors: Ting-lan Ji, Donglai Liu, Glen W.

Patent number: 10222461Abstract: A system for ultrasonic imaging utilizing multiple sets of transmit pulses differing in amplitude, frequency, phase, and/or pulse width. One embodiment has phase differences between the k transmit signal as 360 k degrees providing for constructive interference of the kth order harmonic pulse, while an amplitude modulation of each transmit profile is constant between sets. These sets of pulses are transmitted into media of interest and received echoes from these pulses are combined to form an averaged signal. The averaged pulses represent the net common mode signal received from each of the transmit sets. This combined signal set is used to reconstruct an ultrasound image based on broad beam reconstruction methodology.Type: GrantFiled: October 28, 2007Date of Patent: March 5, 2019Assignee: Shenzhen Mindray Bio-Medical Electronics Co., Ltd.Inventors: Glen McLaughlin, Ting-Lan Ji

Publication number: 20160011498Abstract: Methods of probing a material under investigation using an ultrasound beam. Echolocation data is generated using a multi-dimensional transform capable of using phase and magnitude information to distinguish echoes resulting from ultrasound beam components produced using different ultrasound transducers. Since the multi-dimensional transform does not depend on using receive or transmit beam lines, a multi-dimensional area can be imaged using a single ultrasound transmission. In some embodiments, this ability increases image frame rate and reduces the amount of ultrasound energy required to generate an image.Type: ApplicationFiled: April 15, 2015Publication date: January 14, 2016Inventors: Glen W. McLaughlin, Ting-Lan Ji, David Napolitano
