An x-ray procedure that produces an image (tomogram) of a selected layer of tissue
A test using computers and x-rays to see part of the body after the injection of a die
Any of several techniques for making detailed x-rays of a predetermined plane section of a solid object
An X-ray technique that produces a detailed cross-section of tissue structure at a predetermined depth
A technique used in remote sensing for retrieving atmospheric parameters in a plane (cross-section) by taking measurements at different angles (and possibly different frequencies)
Radiological technique for obtaining clear X-ray images of internal structures by focusing on a specific plane within the body to produce a cross-sectional image. It allows the examination of structures that are obscured by overlying organs and soft tissues and do not show up clearly on conventional X-ray images. See also computed axial tomography. computed axial tomography computed tomography positron emission tomography
from the Greek words "to cut or section" (tomos) and "to write" (graphein), in nuclear medicine, it is a method of separating interference from the area of interest by imaging a cut section of the object
A method of producing a 3-D image of internal objects by comparing the energy (usually x-rays) that is absorbed at various angles about the outside of the object See also Computed Tomography
Of or pertaining to imaging by the method of rotating a radiation source and the accompanying sensor so that areas outside the required plane of investigation are not in focus
The patient was examined using a positron emission tomographic system.
(Tıp, İlaç) Radiography in which a three-dimensional image of a body structure is constructed by computer from a series of plane cross-sectional images made along an axis ― called also computed axial tomography computerized axial tomography computerized tomography
technique for creating detailed images of bodily tissues by injecting positron-laden material into the body and recording the gamma rays emitted over a period of about two hours (Medicine)
or computed tomography (CT) Diagnostic imaging method using a low-dose beam of X rays that crosses the body in a single plane at many different angles. Conceived by William Oldendorf and developed independently by Godfrey Hounsfield (b. 1919) and Allan M. Cormack, who shared a 1979 Nobel Prize for their inventions, this major advance in imaging technology became generally available in the early 1970s. Detectors record the strength of the exiting X rays; this information is then processed by computer to produce a detailed two-dimensional cross-sectional image of the body. A series of such images in parallel planes or around an axis can show the location of abnormalities (especially tumours and other masses) more precisely than can conventional X-ray images
A diagnostic technique that uses a computer and an x-ray machine to take a series of images that can be transformed into a clear and detailed image of a joint
a non-invasive procedure that takes cross-sectional images of the brain or other internal organs; to detect any abnormalities that may not show up on an ordinary x-ray
Computed Tomography (also known as CAT Scan, Computed Axial Tomography) is a technical advance over Conventional Tomography A x-ray source and detector are moved about a focal plane in the body, as in Conventional Tomography, but a computer is used to generate an accurate cross-sectional image of the body This powerful technique is used to evaluate pathology throughout the body Administration of intravenous iodinated contrast aids in the evaluation of solid organ disease, for example metastatic lesions within the liver Iodinated contrast may also be injected into the joints in the detection of ligament tears or other joint abnormalities
a diagnostic imaging method in which x-ray measurements from many angles are combined in an image CT scans help physicians evaluate bone structures and bleeding within the skull and spine
Method of visualizing the body's soft tissues Using x-rays with the beam passing repeatedly thorugh the body part, the CT scans while a compurter calculates tissue absorption at each point scanned
(Also called a CT or CAT scan ) - a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called "slices"), both horizontally and vertically, of the body A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs CT scans are more detailed than general x-rays

Tomography in which computer analysis of a series of cross-sectional scans made along a single axis of a bodily structure or tissue is used to construct a three-dimensional image of that structure. The technique is used in diagnostic studies of internal bodily structures, as in the detection of tumors or brain aneurysms
Also known as CT scans or CAT scans (for Computer Assisted Tomography) This technique uses X-rays to generate computerized images (pictures) of all parts of the body The technique can create pictures in 2D and 3D
A computerized x-ray examination that allows visualization of the brain or other parts of the body The dose of radiation received by the baby is very small (about equal to one chest x-ray)
Tomography in which a computer-generated image of a biological activity within the body is produced through the detection of gamma rays that are emitted when introduced radionuclides decay and release positrons. Imaging technique used in diagnosis and biomedical research. A chemical compound labeled with a radioactive isotope (see radioactivity) that emits positrons is injected into the body, and detectors measure their activity in the tissues as they combine with electrons and are annihilated. Computers analyze, integrate, and reconstruct the data to produce images of the organs scanned. PET is particularly useful for studying brain and heart functions
