1. A method for detecting endometrial peristalsis, applied to an ultrasound imaging device, wherein the ultrasound imaging device at least comprises an ultrasound probe, a processor and a human-machine interaction apparatus; and the method comprises:
transmitting, by the ultrasound probe controlled by the processor, an ultrasound wave to an endometrium, and receiving, by the ultrasound probe controlled by the processor, echoes of the ultrasound wave to obtain ultrasound echo data;
performing, by the processor, imaging on the ultrasound echo data to obtain an ultrasound image of the endometrium;
determining, by the processor, peristaltic displacements of points in the endometrium within a preset time length based on the ultrasound echo data,
wherein determining, by the processor, the peristaltic displacements of points in the endometrium within the preset time length based on the ultrasound echo data comprises:
selecting, from the ultrasound echo data, a first one-dimensional ultrasound echo data segment centered on a first point in the endometrium at a first moment, searching, in a one-dimensional search region covering the first point, a second one-dimensional ultrasound echo data segment at a second moment in a greatest correlation with the first one-dimensional ultrasound echo data segment, a position of a center point of the second one-dimensional ultrasound echo data segment being a position of the first point at the second moment, and obtaining a peristaltic displacement of the first point between the first moment and the second moment; and
obtaining, by analogy, the peristaltic displacements of the points in the endometrium at different moments within the preset time length;
calculating, by the processor, a peristaltic parameter of the endometrium based on the peristaltic displacements of the points in the endometrium within the preset time length, wherein the peristaltic parameter is used to describe a motion status of the endometrial peristalsis; and
displaying, by the human-machine interaction apparatus controlled by the processor, the peristaltic parameter.
