Claim 0:
1. A method for acquiring labeled data, comprising:
acquiring a 3D-3D registration sample, wherein the 3D-3D registration sample comprises a sample 3D image, a reference 3D image and 3D-3D registration data, and the 3D-3D registration data comprises correspondence data between the sample 3D image and the reference 3D image;
generating at least one dual-2D-image based on the sample 3D image, wherein each dual-2D-image is a combination of 2D projection images of the sample 3D image in two different directions; and
generating 2D-3D registration data corresponding to each dual-2D-image based on the 3D-3D registration data, wherein each 2D-3D registration data comprises correspondence data between the dual-2D-image and the reference 3D image;
wherein acquiring the 3D-3D registration sample comprises:
acquiring the reference 3D image and at least one set of sample 2D images, wherein each set of sample 2D images comprises a number of 2D images acquired by imaging a same object in a number of different directions respectively;
reconstructing each set of sample 2D images into one sample 3D image respectively; and
acquiring the correspondence data between each sample 3D image and the reference 3D image by a 3D-3D image registration; and

wherein generating at least one dual-2D-image based on the sample 3D image comprises combining, in each set of sample 2D images, every two 2D images having a predetermined angular interval into the dual-2D-image.
