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

摘要

When assembling images of incoherent radiators sampled from different angles, three dimensional imaging has relied on recognizing the features in different images. If the goal is to produce a 3D model of the object, tomographic methods such as cone-beam reconstruction can produce high-quality models. Tomographic methods do not exactly apply to modeling of surface objects due to the opaque nature of typical objects and the inaccuracy of the pencil-line assumption of the point spread function (PSF).
