1. A tissue imaging method, comprising:
inserting an electronic probe into a lesion area of a patient to ablate tissue of the lesion area;
capturing a first image including the lesion area by using an imaging apparatus;
vibrating the electronic probe to generate displacement of at least a portion of the tissue of the lesion area, and capturing a second image, including the lesion area when the electronic probe vibrates, by using the imaging apparatus, wherein the displacement of the electronic probe by vibration is larger than a size of a single pixel of the first image and the second image, and a vibration frequency of the electronic probe is larger than a frames per second of the image captured by the imaging apparatus;
generating a correlation image according to a correlation between the first image and the second image; and
computing an ablation boundary according to the correlation image;
wherein the electronic probe vibrates in a first direction and a second direction from an initial position, and an angle value between a first vector corresponding to the first direction and a second vector corresponding to the second direction is larger than an angle threshold value, wherein the angle value is detected by a sensor of the electronic probe and a sensor of the imaging apparatus;
wherein the angle threshold value is a value to ensure the electronic probe being able to obtain the correlation image for determining the ablation boundary.
