摘要： Disclosed is an ultrasound imaging system that includes a remote server configured for communication with a first ultrasound imaging console and a second ultrasound imaging console. The server is configured to receive, from the first ultrasound imaging console, an upload request for a custom image setting, receive and store the custom image setting. The server is further configured to output, to the second ultrasound imaging console, data representative of the custom image setting; receive a request for the custom image setting; retrieve and send, to the second ultrasound imaging console, the custom image setting such that the second ultrasound imaging console can generate an image with the custom image setting.

摘要： Systems, devices, and methods for ultrasonic imaging by sparse sampling are provided. In one embodiment, an ultrasound imaging system comprises an array of ultrasound transducer elements, electronic circuitry in communication with the array of ultrasound transducer elements and configured to select a first receive aperture of the array comprising a plurality of contiguous ultrasound transducer elements and at least one non-contiguous ultrasound transducer element, and a beamformer in communication with the electronic circuitry. Each ultrasound transducer element of the first receive aperture is configured to receive reflected ultrasound echoes and generate an electrical signal representative of imaging data. The beamformer is configured to receive the electrical signals generated by the first receive aperture and apply different weight to the electrical signals generated by the contiguous ultrasound transducer elements and the electrical signal generated by the at least one non-contiguous ultrasound transducer element.

摘要： An ultrasound imaging system transmits two beams in succession in the same beam direction, the waveform of the second beam being a phase inverted form of the first waveform, and each waveform containing first and second major frequency components. Echoes are received from along the beam direction in response to each beam transmission, and are processed by additively and subtractively combining the two echo sequences on a common depth basis. The echo components resulting from this processing extend from high frequencies for good near field resolution to low frequencies for good depth penetration, and include fundamental, harmonic, and sum or difference frequency components. The linear and nonlinear echo signal components may be frequency compounded for speckle reduction.
