摘要： A diagnostic ultrasound image of a region of interest (ROI) of a body is formed by transmitting into the ROI at least a first and a second ultrasound pulse, in which the second pulse is phase-shifted relative to the first pulse by an amount other than 0 or 180 degrees. Discretized receive signals from the pulses are interleaved to form a resultant operating signal that is detected and beamformed as the operating signal.

摘要： Disclosed are a method and a device for detecting displacement in elastography. The method comprises: acquiring a target point, acquiring a cross-correlation phase calculation location of the target point in a second frame image; calculating a cross-correlation phase according to the cross-correlation phase calculation location; calculating a longitudinal displacement result according to the cross-correlation phase; and calculating a gradient of the displacement result to obtain a strain result. Through the elastography method and device, I/Q-channel echo baseband signals, obtained by downsampling, of two frames before and after compression are acquired, displace information between the two frames is rapidly detected by guiding phase estimation, and axial gradient calculation is performed to obtain strain information, which can not only obtain a strain image of high quality but also reduce the calculation amount, thereby satisfying the clinical real-time requirement.
