Computed tomography (CT) is a medical imaging method employing tomography created by computer processing. Digital geometry processing is used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. CT produces a volume of data which can be manipulated, through a process known as "windowing", in order to demonstrate various bodily structures based on their ability to block the X-ray/Röntgen beam. Although historically the images generated were in the axial or transverse plane, orthogonal to the long axis of the body, modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures. Although most common in medicine, CT is also used in other fields, such as nondestructive materials testing. Another example is the DigiMorph project at the University of Texas at Austin which uses a CT scanner to study biological and paleontological specimens. Usage of CT had increased dramatically over the last number of years with an estimated 72 million scans performed in 2007. From Wikipedia under the

Q. Drank 500 ml 1% barium sulfate for a CT scan. I have drank over the required 4 cups of water. How is the barium sulfate eliminated? Does it all come out in a bowel movement? Is some of it absorbed by the body? How long does it take to leave the body? If I don't have a bowel movement soon, should I take a laxative? Asked by Marlie S - Fri Mar 28 20:02:23 2008 - - 1 Answers - 0 Comments A. It will be eliminated during bowel movements. They should have given you a stool softener. It will come out as little white rock like substances. You may just notice your stool being white. Not always pleasant and easier if you have taken a stool softener. A laxative may make cramping worse. There are softener available over the counter at most drug stores like Walgreens. You may feel constipated for a day, but eventually, they will pass. Keep drinking the water. Answered by researcher - Fri Mar 28 20:12:58 2008 If I get a CT scan for my sinuses will it also detect a brain tumor? Q. Sounds crazy but I have sinus headaches along with a big bump on the top of my head. Whenever my sinus hurt that bump hurts also, pressure I guess.

Q. Some of us know that the X-ray machine needs a darkroom for the processing of the radiographs. I'm just wondering if the CT scan still needs a darkroom to produce diagnostic images and a cassette that will contain the film. Asked by "TORPEdo" - Thu Sep 17 12:31:42 2009 - - 2 Answers - 0 Comments A. Nope! The CT scanner contains an x-ray tube, the same as a regular x-ray room, but has detectors on the other side, rather than a film cassette. The tube and detectors spin around you (this part is called the gantry) acquiring information continuously (in a spiral) as you move through it on the table. All the information from the detectors is gathered by the Image Capture System (called raw data) which is then reconstructed, first into a usable image, and then into any way the operator chooses - in different planes, in different slice thicknesses, in different brightness/contrasts ('windows') concentrating on different body parts (ie, bone or soft tissue or lung), or in cool 3D pictures. These images are then sent electronically to a… [cont.] Answered by ausrad - Sun Sep 20 18:59:31 2009 From Yahoo Answer Search: "CT scan" |
