Computed tomography projection geometry

What is projection measurement data in CT?
Projection data, by their very nature, are a result of interaction between the radiation used for imaging and the substance of which the object is composed.
To a first approximation, such interactions can be modeled as measuring integrals of some characteristic of the object..
What is the advantage of CT over projection radiography?
CT scanning has several advantages over traditional two-dimensional medical radiography.
First, CT eliminates the superimposition of images of structures outside the area of interest.
Second, CT scans have greater image resolution, enabling examination of finer details..
What is the geometry of CT scan?
The scanner design is based on a partial-ring PET system and a small-animal CT assembled on a rotatory gantry without axial displacement between the geometric centers of both fields of view (FOV)..
What is the projection of a CT scan?
CT images are reconstructed from approximately 1000 projections that are acquired as the x-ray tube rotates through 360\xba around the object (patient)..

Projections (parallel beam type) for the reconstruction are calculated analytically by defining Shepp logan phantom head model with coverage angle ranging from

In technical drawing and computer graphics, a multiview projection is a technique of illustration by which a standardized series of orthographic two-dimensional pictures are constructed to represent the form of a three-dimensional object.
Up to six pictures of an object are produced, with each projection plane parallel to one of the coordinate axes of the object.
The views are positioned relative to each other according to either of two schemes: first-angle or third-angle projection.
In each, the appearances of views may be thought of as being projected onto planes that form a six-sided box around the object.
Although six different sides can be drawn, usually three views of a drawing give enough information to make a three-dimensional object.
