an x-ray picture of internal organs of the body.
If a person takes a particular drug (or medicine) over some time, the drug may gradually become less effective as their body may respond less to it. This is known as drug tolerance. If this happens, it may be necessary either to increase the dose or change to another drug.
A method of producing three-dimensional images of the internal structures of a solid object (as the human body or the earth) while blurring out the images of other areas. Reference: B1
A special technique to show in detail images of structures lying in a plane of tissue.
(medicine) obtaining pictures of the interior of the body
A technique of x-ray photography that reveals only one plane of a body's internal structure and eliminates all others. A computer can then build a 3-dimensional image from the images of the different planes.
the use of x-rays to produce images of one specific layer of tissue
An X-ray technique that produces a detailed cross-section of tissue structure at a predetermined depth.
The procedure used to obtain a set of slice images of the patient.
techniques used to obtain an image of a selected plane section within an object. It creates cross-sectional images or slices in 3D of the interior of the investigated object without physically cutting it. Conductance tomography for determining 3D solids distributions within thickener feedwells and the bulk of thickeners involves measurement of changes in conductivity between a number of sensors.
The process for generating a tomogram , a two-dimensional image of a slice or section through a three-dimensional object. Tomography achieves this remarkable result by simply moving an x-ray source in one direction as the x-ray film is moved in the opposite direction during the exposure to sharpen structures in the focal plane, while structures in other planes appear blurred. The tomogram is the picture; the tomograph is the apparatus; and tomography is the process. See the entire definition of 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.
X-ray pictures of body parts that show sections of the anatomy instead of full views. This approach allows for a better view of small areas.
a diagnostic technique using X-ray photographs in which the shadows of structures,, before and behind the section under scrutiny, do not show.
The visual presentation of cross–sectional slices through an object.
The technique of obtaining an X-ray picture of a selected layer in an object.
technique used to study the human body through the imaging of radiological slides of the organs.
A series of detailed pictures of areas inside the body; the pictures are created by a computer linked to an x-ray machine.
The reconstruction of the temperature structure of the ocean from acoustic signals in multiple vertical planes. See acoustic tomography.
a procedure where internal body images at a predetermined plane are recorded by means of the tomograph, a computer-driven device that builds the image from multiple X-ray measurements; tomography is used in CAT scan and PET scan
Tomography is imaging by sections or sectioning. A device used in tomography is called a tomograph, while the image produced is a tomogram. The method is used in medicine, archaeology, biology, geology, materials science and other sciences.
