[Image displacement elimination method in tomosynthesis].
Computerized Tomography needs projected images from all directions, tomosynthesis doesn't need the information from all directions, but its reconstruction image is indistinct. In this paper, we introduce Frequency Domain Deconvolution Imaging(FDDI) which proposed recently. FDDI overcomes shortcoming of tomosynthesis, but FDDI's calculation is large, and its zero frequency will lose. We propose a new method-image displacement elimination method(IDEM), it overcome shortcomings of FDDI and can solve convolution equation set in space domain quickly.
