1. A method for image guidance, applied to a medical device, wherein the medical device comprises a patient positioning mechanism and an imaging mechanism, the imaging mechanism is configured to be capable of capturing medical images of a patient on the patient positioning mechanism at a plurality of capturing angles by rotating around the patient positioning mechanism; and the method comprises:
controlling the imaging mechanism to rotate around the patient positioning mechanism;
acquiring a first image in response to that the imaging mechanism is rotated to any one of the capturing angles, the first image being a medical image of the patient captured by the imaging mechanism at a first capturing angle, and the first capturing angle being a capturing angle to which the imaging mechanism is currently rotated; and
performing, after a second image corresponding to the first image is acquired, image guidance using a combination of the first image and the second image as an indicator of a current position state of the patient, wherein the second image is a medical image of the patient captured by the imaging mechanism at a second capturing angle, the second capturing angle is one of the capturing angles, the second capturing angle is at a first preset angle with the first capturing angle, and an angle interval between any two adjacent capturing angles among the capturing angles is smaller than the first preset angle.
