1. A CBCT image acquiring method based on adaptive sampling, comprising:
a step of acquiring a plurality of image scanning points based on a previously acquired medical image for a target patient, by acquiring an image for every image scanning point based on the medical image, sorting images for image scanning points based on a quantitative value for each of images for image scanning points, selecting a plurality of images according to a predetermined criterion, among sorted images for image scanning points, and acquiring the image scanning points corresponding to the plurality of selected images as the plurality of image scanning points;
a step of acquiring a plurality of cone beam computed tomography (CBCT) images for the target patient based on the plurality of image scanning points; and
a step of acquiring a final CBCT image for the target patient based on the plurality of CBCT images.
