X-ray tomography is a process of reconstructing the internal structure of a physical body using X-ray images of the body taken from different dimensions. Mathematically, the problem is to recover a non- negative function f(x) form a collection of line integrals of function ‘f’. This technique helps obtain digital information on their 3-D geometries and properties. The earliest clinical tomography scanner had an X-ray source and a single detector. Now computed tomography uses ionizing x-ray to generate images by emitting a-rays from a fan-beam source that rotates around the patient.
After passing through the physical body, the beam is incident on a ring of x-ray detectors, which register a value for the degree of attenuation of the X-ray beam. The values reflect the density of the tissue in tiny volumes of space within the physical body known as voxels. Computational models are applied to assign a gray scale to the individual voxels to make up the 2D cross-sectional image. Once the process is done, the data set may also be constructed into 3-D computer generated the model, in which colors can be applied to represent tissues.
Tomography imaging consists of directing X-rays at an object from multiple orientations and measuring the decrease in the intensity of a series of linear paths.
Before you initiate the process, the preparation necessary for CT scanning is to ensure that the object fits inside the field of view and that does not move during the scan. Later the data is collected in the form of a sequence of image files which can be visualized and analyzed using a wide variety of 2D and 3D based image processing tools. The two standard modes of 3D visualization are volume rendering and isosurfacing.
X-ray tomography is used in wide variety of domain like archaeology, Biomedical, spray nozzle, small electronic components, foods, etc. Due to its multi scalable applicability, it is widely used diesel nozzle internal microstructure. To own an X-ray tomography in USA you need to find the best manufacturer. These devices are complex and readily require a hefty investment. There are different types of such machine is available and as the manufacturer vary, you can easily see the variation in the gray level value. So, it is better to own reputed brand x-ray machine because even a slightest of variation in the data set can cause the extremely awkward result. In medical science, you cannot take such risk at all.

The uses of X-ray tomography in Clinical Practice:
- It produces high-resolution 2D and 3D images and provides rapid evaluation of bone and soft tissue.
- It provides an excellent 3D assessment of bone in the setting of trauma and can be utilized to assess fracture with metallic fixation hardware in situ.
- Reconnaissance imaging of samples for optimal geochemical exploitation like locating crystal central sections, spiral axes, etc.
- As an alternative to MRI, X-ray tomography can be combined with arthrography to assess intra-articular derangement of joints.
