It depends on the manufacturer and how old the machine is.
Most new CT scanners take slices every 0.5 mm. Older ones use 1.0-3.0 mm. Depending on the protocol that is selected, your scan will be reconstructed at thicker slices (from 1.0-10mm) to reduce the amount of images archived and that need to be read by the radiologist. A typical CT scan of the Abdomen/Pelvis generates 1500-2000 slices at 0.5mm. Usually slices are reconstructed at 5.0mm 'cuts' which combines usable quality and lower amount of images that need to be read and archived. The 0.5mm cuts are saved as a volume of information that can be reconstructed, re-cut up, and 3D modeled in a variety of different ways depending on what and why the exam is being performed.

What does an MRI use to scan soft tissues?
it uses infer red
What does CT stand for medically?
You might be referring to CT scan, which is another name for CAT scan used to show human body in various slices using X-ray.
How do you acquired image in second and third and fourth generation of ct scan?
 4th Generation: continuous movement of the patient table along the cephalocaudal direction (z-axis) of the scanner. Axial slices were generated through interpolation along the z-axis prior to Filtered Back- Projection (FBP) reconstruction
What is the name of the scan that is not nuclear?
The scan that is not nuclear is typically referred to as an MRI (magnetic resonance imaging) scan. It uses a magnetic field and radio waves to create detailed images of organs and tissues in the body.
Is a MRI a treatment?
No. It is not a treatment it is a scan. An MRI is a Magnetic Resonance Imaging. MRI are used for imaging tissues.
Why do they inject dye into you before a ct scan?
Dye is used to enhance tissues, to increase contrast between tissues that receive blood and structures that do not. There can be scans before, during, and at different delays after injection. The enhancement pattern, or lack of enhancement, is the basis for diagnosis (along with morphologic information from the scan).
What is the mean of scan traffic volume?
propagational behaviour of worms or programs which generate the traffic which consist of random internet ip address of vulnerable computer...is called scan traffic volume...generated by worms....!
If you have a clear CAT scan how can you be in coma?
Something in a CAT scan might explain a coma, but it is not a definitive test. Just because a computer "looks normal" that is no indication that it will run. This is a crude analogy. The CAT scan images tissues. It does not evaluate how those tissues are operating - or not. Though there are a few "clues" to what is going on in a CAT scan, the scan is not the "litmus test" for actual brain operation and function. A CAT scan may be performed as part of the workup to find out why someone is in a coma. It will allow the physicians to determine if there is a "physical" cause or not. If nothing shows up, the cause of the coma must be investigated further. A coma can be a difficult thing to find a cause for.
How does an image from a CT scanner differ from a regular X-ray scanner?
The CT scan uses many X-ray images in thin slices to make a 3D image.
What does density mean on a ct scan?
On a CT scan, density refers to the degree of attenuation of X-rays as they pass through different tissues in the body, which is represented in Hounsfield Units (HU). Denser tissues, such as bone, appear brighter (higher HU values), while less dense tissues, like air or fat, appear darker (lower HU values). This variation in density helps radiologists differentiate between various types of tissues and identify abnormalities or conditions within the body.
What is a CT scan?
A Computed Tomography Scan, also known as Computed Axial Tomography or CAT Scan, uses X rays and computers to produce detailed images of the inside of a body. It provides three-dimensional views of the body's soft tissues such as blood vessels, muscles, and organs.
What is a ct-scan?
A Computed Tomography Scan, also known as Computed Axial Tomography or CAT Scan, uses X rays and computers to produce detailed images of the inside of a body. It provides three-dimensional views of the body's soft tissues such as blood vessels, muscles, and organs.
