Computed tomography factor

What are the factors affecting image in tomography?
Affected by:
Noise: higher noise = worse contrast differentiation.Tube current: lower tube current = more noise (see above)Inherent tissue properties: difference in linear atteunation coefficient of adjacent imaged objects determines contrast.Beam kilovoltage: higher beam energy generally reduces contrast..
What are the factors affecting image quality in CT?
Fundamentally, image quality in CT, as in all medical imaging, depends on 4 basic factors: image contrast, spatial resolution, image noise, and artifacts..
What are the factors of CT?
Three main factors are varied systematically: the magnification of the CT, the numbers of views (NoV), and the set-up of the scanning mode.
In the course of measurement evaluation several GD&T parameters are determined such as diameter of holes, distances between the holes, flatness and perpendicularity..
What is the risk factor of CT?
Risks of CT Scan
The amount of radiation used during a CT scan is considered minimal; therefore, the risk for radiation exposure is low.
If you are pregnant or suspect that you may be pregnant, you should notify your physician.
Radiation exposure during pregnancy may lead to birth defects..

The term “computed tomography,” or CT, refers to a computerized x-ray imaging factor for a successful clinical outcome.
