1. An image presentation method for medical imaging, comprising:
obtaining, for a target area including a first target, (i) a first image of the target area, which is taken without the use of a contrast agent in the target area, and (ii) a second image of the target area, which is taken with the use of a contrast agent in the target area;
subtracting the second image from the first image to obtain a subtraction image;
extracting a contour of a second target from the subtraction image to obtain a contour image of the second target;
registering, based on a same marker, the contour image of the second target and a currently-acquired image; and
displaying the registered contour image of the second target and the currently-acquired image in a superimposed manner,
wherein the registering and the displaying the contour of the second target and the currently-acquired image comprise:
determining, based on the second image, two reference points on the contour of the second target and a mark point on the marker:
calculating a position relationship between the two reference points and the mark point; and
from each one of a set of currently-acquired images that includes the currently-acquired image:
determining a corresponding mark point on the same marker:
registering the contour image of the second target and a respective currently acquired image from among the set of currently-acquired images based on the position relationship; and
displaying the contour of the second target and the respective currently-acquired image in a superimposed manner using a pixel translation algorithm.
