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 a multiple of 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 system and a method for ultrasound elastography and a method for dynamically processing frames in real time. The system includes an elasticity processing apparatus having an elasticity information detecting module for extracting elasticity information representing the elasticity of a target to be detected; a quality parameter calculating module for calculating at least a quality parameter reflecting quality of each elasticity image corresponding to the elasticity information; and a frame processing module for determining whether to output corresponding elasticity image based on the quality parameter of each elasticity image. When calculating a strain of consecutive images, the parameter reflecting the quality of each image is also computed, through which, the current elasticity image is determined whether to be displayed, thus avoiding the situation that colors of acquired successive elasticity images may vary greatly due to large difference existing in stress.

摘要： An ultrasonic imaging device and a method for detecting endometrial peristalsis. The method comprises: acquiring ultrasound echo data of the endometrium (1), and determining on said basis the peristaltic displacement or peristaltic speed of a point in the endometrium within a preset period of time (2); calculating peristalsis parameters of the endometrium according to the peristaltic displacement or the peristaltic speed of the point in the endometrium within the preset period of time, the peristalsis parameters being used to describe the moving state of endometrial peristalsis (3); and displaying the peristalsis parameters (4). Thus, peristalsis parameters are calculated automatically without relying on the subjective determination of an ultrasound doctor, which improves the accuracy and efficiency of the detection of peristalsis.
