WebApr 11, 2024 · The filtered back projection (FBP) algorithm is a classical method widely applied in CT image reconstruction. Since its first introduction in the 1970s by R. A. Crowther and colleagues [ 37 ], FBP has become the mainstream technology in the field of CT image reconstruction due to its advantages in computational efficiency and image … WebThe main principle of image reconstruction is this: When multiple 2d projection images are acquired of an object from many angles, one can use mathematical tools to reconstruct a 3d representation of that object. It is with this principle that we are able to acquire 3d images in medical imaging modalities: Computed Tomography (CT), Positron ...
