What is the medical definition for tomography?

Medical Definition of tomography : a method of producing a three-dimensional image of the internal structures of a solid object (as the human body) by the observation and recording of the differences in the effects on the passage of waves of energy impinging on those structures. — called also stratigraphy.

What is the principle of tomography?

Computer Tomography – Principle of X-Ray Tomography X-ray tomography uses the ability of X-ray radiation to penetrate objects. On the way through an object, part of the impinging radiation is absorbed. The longer the radiographic length of the object, the less radiation escapes from the opposite side.

Is tomography an xray?

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 is the difference between CT scan and tomography?

A computerized tomography (CT) scan is usually a series of X-rays taken from different angles and then assembled into a three-dimensional model by a computer. Tomography means a picture of a slice.

What does topography mean in medical terms?

to·pog·ra·phy (tō-pog’ră-fē), In anatomy, the description of any part of the body, especially in relation to a definite and limited area of the surface.

What are the components of CT scan?

CT scanners are composed of three important elements: an X-ray tube, a gantry with a ring of X-ray sensitive detectors, and a computer. In this method, images are created using the same physics principles as in conventional radiography.

What types of CT scans are there?

CT Scan Arthrography. CT Scan Bones. CT Scan Brain/ CT Scan Head. CT Scan Chest (CT Scan Lung)

What is the difference between MRI and CT scan?

The biggest difference between MRI and CT scans is that MRIs use radio waves while CT scans use X-rays. Following are several others. MRIs are typically more expensive than CT scans. CT scans may be quieter and more comfortable.

What is MRI scan used for?

Magnetic resonance imaging (MRI) of the body uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the inside of your body. It may be used to help diagnose or monitor treatment for a variety of conditions within the chest, abdomen, and pelvis.
