1. An ultrasound imaging method, comprising:
transmitting a first ultrasound wave and a second ultrasound wave alternately to a target area of an object to be examined;
receiving an ultrasound echo of the first ultrasound wave returned from the target area to obtain first echo data and an ultrasound echo of the second ultrasound wave returned from the target area to obtain second echo data;
obtaining a first elasticity image frame sequence of the target area according to the first echo data and a B-mode image frame sequence of the target area according to the second echo data, wherein the first elasticity image frame sequence comprises at least two frames of elasticity images; and
performing an inter-frame processing, wherein the inter-frame processing comprises:
determining a first elasticity image and a second elasticity image from the at least two frames of elasticity images, wherein the first elasticity image and the second elasticity image are different and correspond to a first B-mode image and a second B-mode image of the B-mode image frame sequence, respectively, and wherein at least one additional B-mode image of the B-mode image frame sequence is inserted between the first elasticity image and the second elasticity image;
determining a time interval from the first elasticity image to the second elasticity image in the first elasticity image frame sequence;
determining a number of frames of the at least one additional B-mode image inserted between the first elasticity image and the second elasticity image;
determining a direction and amplitude of a displacement of the target area according to the first B-mode image, the at least one additional B-mode image, and the second B-mode image;
adjusting the first elasticity image and the second elasticity image according to the direction and the amplitude of the displacement;
generating, according to the determined time interval, the determined number of frames of the at least one additional B-mode image, the adjusted first elasticity image, and the adjusted second elasticity image, at least one frame of additional elasticity image corresponding to the at least one additional B-mode image inserted between the first elasticity image and the second elasticity image;
inserting the generated at least one frame of additional elasticity image into at least a portion of the first elasticity image frame sequence to obtain a second elasticity image frame sequence comprising the generated at least one frame of additional elasticity image and at least the portion of the first elasticity image frame sequence; and
displaying the second elasticity image frame sequence, wherein a number of frames of the second elasticity image frame sequence is greater than a number of frames of the first elasticity image frame sequence.
