Binary tomography

WebComputed tomography (CT) is a non-invasive imaging technique that reconstructs images of non-accessible or non-visible objects from a set of projection data [ 1, 2 ]. Computed tomography has a wide range of applications in diverse fields, such as medicine, science, industrial non-destructive testing, and electron tomography [ 3 – 8 ]. WebJan 1, 2024 · Tomography is a field of image processing which deals with reconstruction of unknown images from available projection data [ 7 ]. Mathematically, the image can be modeled by a function whose codomain or range may be continuous or discrete set. In the Computerized Tomography the image function has a continuous range.
