我们报告了等倾斜层析成像的发展，用于从许多2D投影重建3D物体。在伪极快速傅里叶变换和迭代算法的过采样方法的结合中，等倾斜层析成像比传统层析成像具有更好的3D重建能力，传统层析成像由于使用等角度二维投影而具有固有的缺点。我们相信这种通用方法将在x射线成像、电子显微镜、相干衍射显微镜和其他层析成像领域得到应用。
We report the development of equally sloped tomography for the reconstruction of a 3D object from a number of 2D projections. In a combination of pseudopolar fast Fourier transform and the oversampling method with an iterative algorithm, equally sloped tomography makes superior 3D reconstruction to conventional tomography that has an intrinsic drawback due to the use of equally angled 2D projections. We believe this general approach will find applications in x-ray imaging, electron microscopy, coherent diffraction microscopy, and other tomographic imaging fields.
