摘要
考虑由过井间和地面三侧的Ｒａｄｏｎ变换重建问题用仿射变换，建立了这个重建问题与已知函数的圆外Ｒａｄｏｎ变换反演函数的关系。
We consider the problem of reconstructing a function on cross-borehole and three side on ground from its Radon transform. We use affine transform and establish relations between it and the reconstruction of a function on the exterior of a disk from its Radon transform. Its unique theroem is obtained in L 2 space.
