This produces signals that are then analyzed by the machine’s computer to create cross-sectional images, or “slices,” of the patient’s body. These sections, which are known as tomographic pictures, can provide a clinician with more specific information than traditional x-rays. <a href="/w/index.php?title=A_three-dimensionalhttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/&action=edit&redlink=1" class="new" title="A three-dimensionalhttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/ — pagină inexistentă">A three-dimensional</a> (3D) image of the patient can be created once a number of successive slices have been collected by the machine’s computer. This makes it easier to identify the patient’s basic anatomy as well as any potential tumors or anomalies. </p><p>How does CT work? A CT scanner employs a <a href="/w/index.php?title=Motorized_x-rayhttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/&action=edit&redlink=1" class="new" title="Motorized x-rayhttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/ — pagină inexistentă">motorized x-ray</a> source that spins around the circular opening of a donut-shaped frame called a gantry, in contrast to a traditional x-ray, which uses a stationary x-ray tube. In a CT scan, the patient is lying on a bed that gently rotates across the gantry as a narrow beam of x-rays is shot into the body by <a href="/w/index.php?title=The_x-ray_tubehttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/&action=edit&redlink=1" class="new" title="The x-ray tubehttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/ — pagină inexistentă">the x-ray tube</a>. Special digital x-ray detectors, which are placed immediately across from the x-ray source, are used in CT scanners in place of film. The detectors catch the x-rays as they leave the patient and send them to a computer. </p><p>Each time the x-ray source completes one full rotation, <a href="/w/index.php?title=The_CT_computerhttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/&action=edit&redlink=1" class="new" title="The CT computerhttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/ — pagină inexistentă">the CT computer</a> uses sophisticated mathematical techniques to construct a two-dimensional image slice of the patient. The thickness of the tissue represented in each image slice can vary depending on the <a href="/w/index.php?title=CT_machinehttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/&action=edit&redlink=1" class="new" title="CT machinehttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/ — pagină inexistentă">CT machine</a> used but usually ranges from 1-10 millimeters. When a full slice is completed, the image is stored and the motorized bed is moved forward incrementally into the gantry. The x-ray scanning process is then repeated to produce another image slice. This process continues until the desired number of slices is collected. </p><p>The computer can either display the image slices separately or stack them to create a 3D image of the patient that displays the skeleton, organs, tissues and any anomalies the doctor is hoping to spot. This approach has various benefits, including the <a href="/w/index.php?title=Ability_to_rotatehttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/&action=edit&redlink=1" class="new" title="Ability to rotatehttps://mqstechnologies.in/computed-tomography-solution-for-automotive-components/ — pagină inexistentă">ability to rotate</a> the 3D image in space or to see slices one after the other, which makes it simpler to pinpoint the precise location of a potential problem. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Aplicații"><span id="Aplica.C8.9Bii"></span>Aplicații</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ceriu&veaction=edit&section=1" title="Modifică secțiunea: Aplicații" class="mw-editsection-visualeditor"><span>modificare</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ceriu&action=edit&section=1" title="Edit section's source code: Aplicații"><span>modificare sursă</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Întrebuințările ceriului: </p> <ul><li>În <a href="/wiki/Metalurgie" title="Metalurgie">metalurgie</a>: <ul><li>Ceriul este folosit în <a href="/w/index.php?title=Aliajele&action=edit&redlink=1" class="new" title="Aliajele — pagină inexistentă">aliajele</a> de <a href="/wiki/Aluminiu" title="Aluminiu">aluminiu</a>.</li> <li>Adăugând ceriu în <a href="/w/index.php?title=Cast_iron&action=edit&redlink=1" class="new" title="Cast iron — pagină inexistentă">cast irons</a> produce opunerea grafitizării și produce un fier maleabil.</li></ul></li></ul> <div class="mw-heading mw-heading2"><h2 id="Istorie">Istorie</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ceriu&veaction=edit&section=2" title="Modifică secțiunea: Istorie" class="mw-editsection-visualeditor"><span>modificare</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ceriu&action=edit&section=2" title="Edit section's source code: Istorie"><span>modificare sursă</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Ceriul a fost descoperit în <a href="/wiki/Suedia" title="Suedia">Suedia</a> de către <a href="/wiki/J%C3%B6ns_Jakob_Berzelius" title="Jöns Jakob Berzelius">Jöns Jakob Berzelius</a> și <a href="/w/index.php?title=Wilhelm_von_Hisinger&action=edit&redlink=1" class="new" title="Wilhelm von Hisinger — pagină inexistentă">Wilhelm von Hisinger</a>, și, pe plan independent, în <a href="/wiki/Germania" title="Germania">Germania</a> de către <a href="/wiki/Martin_Heinrich_Klaproth" title="Martin Heinrich Klaproth">Martin Heinrich Klaproth</a>, ambele descoperiri fiind făcute în <a href="/wiki/1803" title="1803">1803</a>.
