1. A super-resolution reconstruction method for three-dimensional contrast-enhanced ultrasound images, applied to a first three-dimensional local image sequence comprising microbubbles, comprising:
performing at least one thinning operation on the first three-dimensional local image sequence, wherein the thinning operation is used to enhance motion trajectories of microbubbles; and
performing an image reconstruction operation based on the first three-dimensional local image sequence subjected to the at least one thinning operation, so as to generate a three-dimensional super-resolution image;
wherein the performing at least one thinning operation on the first three-dimensional local image sequence comprises:
performing a first thinning operation on the first three-dimensional local image sequence to generate a second three-dimensional local image sequence corresponding to the first three-dimensional local image sequence, wherein the first thinning operation is used to enhance motion trajectories of microbubbles for a first time; and
performing a second thinning operation on the second three-dimensional local image sequence to generate a third three-dimensional local image sequence corresponding to the second three-dimensional local image sequence, wherein the second thinning operation is used to enhance motion trajectories of microbubbles for a second time;
wherein the performing an image reconstruction operation based on the first three-dimensional local image sequence subjected to the at least one thinning operation, so as to generate a three-dimensional super-resolution image comprises:
performing an image reconstruction operation based on the third three-dimensional local image sequence, so as to generate three-dimensional super-resolution images corresponding to the third three-dimensional local image sequence.
