Grayscale is used in CT scans (Computed Tomography) so the images sent to a computer for analysis contain lighter and darker "spots" of grey. This allows the computer to determine what parts of the body in that scan are blocking the most radiation, and can use it to create a 3D image of the area scanned, such as the skull or diaphragm.

What is a scanning electron microscope used for?
A scanning electron microscope is used to create high resolution images of the surface of a sample by scanning it with a focused beam of electrons. It is commonly used in research and industry to study the surface morphology of materials at a nanometer scale.
What is a scanning probe microscope used for?
A scanning probe microscope is used for observing, studying and measuring surfaces on a fine scale to the level of atoms and molecules. One can find more information about these on Wikipedia.
Explain how a proportion is used to convert measurements on a scale drawing or map to actual lengths or distances?
Hi
Is uv rays used in scanning?
no
Do you use the scanning tunneling microscope for live or dead samples?
The scanning tunneling microscope (STM) is typically used for imaging surfaces of materials at the atomic level, regardless of whether the sample is alive or dead. The STM works by scanning a sharp metal tip over the sample surface and detecting the tunneling current between the tip and the surface, allowing for atomic-scale resolution imaging. It is commonly used in both materials science and nanotechnology research.
What is a scanner and what is it used for?
its a machine that scans things... and it's used for scanning
Why is an odd number of line used for scanning?
An odd number of lines are used in interlaced scanning because, in each field of the TV, the scanning displaces the field by a half of the area. If there were an even number of lines, it would flicker noticably.
What scansion used to find in a poem?

What are data scanning devices?
A scanning device is something that looks over a surface and can transfer information. Scanning devices are used to tell you the price of things for example.
What is offset scanning?
Offset scanning is a technique used in various scanning technologies where the scanning head moves slightly from side to side while capturing an image. This movement helps to reduce the effects of artifacts and improve the overall quality of the scan by ensuring that each point on the scanned object is captured from multiple angles. Offset scanning is commonly used in document scanners and medical imaging devices.
What is Doppler scanning?
Doppler scanning-- A procedure in which ultrasound images are used to watch a moving structure such as the flow of blood or the beating of the heart.
Are gamma rays used in altrasounds?
No. Sound, not radiation, is used in ultrasonic scanning.
