Computed tomography x ray

Is tomography the same as X-ray?

A CT scan, or computed tomography scan, sends radiation through the body.
However, unlike a simple X-ray study, it offers a much higher level of detail, creating computerized, 360-degree views of the body's structures.
CT scans are fast and detailed.
They take longer than X-rays but are still fast (about one minute)..

What are the advantages of CT scan on x-ray?

CT images of internal organs, bones, soft tissue, and blood vessels provide greater clarity and more details than conventional X-ray images, such as a chest X-Ray (see Figures 3 and 4)._{May 1, 2023}.

What is the x-ray tube used in computed tomography?

The CT x-ray tube (typically with energy levels between 20 and 150 keV), emits N photons (monochromatic) per unit of time.
The emitted x-rays form a beam that passes through the layer of biological material of thickness Δx.
A detector placed at the exit of the sample, measures N + u039.

1. N photons, u039
2. N smaller than 0
