Sampling and reconstruction of three-dimensional incoherent radiator, using approximately sampled projections and cone-beam tomography


Journal Article

If the goal is to produce a 3D model of the object, tomographic methods such as cone-beam reconstruction can produce high-quality models. Collecting cones of projections through a central point and inverting the projections to form a 3D mode is called cone-beam tomography. Normal tomography assumes the object is non-scattering, so that the projection is the sum of all the points through the projection. With opaque, diffusely scattering objects, only points on the surface are visible through a limited angle given by occlusions of the object itself. A cone-beam reconstruction of a feature on the surface of an opaque object is then expected to have blurring normal to the surface corresponding to the limited view angle.
