CT

解釋一(中)：電腦斷層掃描（Computerized Tomography，又稱為「計算機斷層掃描」，簡稱CT），是一種影像診斷學的檢查。這一技術曾被稱為電腦軸切面斷層影像（Computed Axial Tomography）。

電腦斷層掃描是一種利用數位幾何處理後重建的三維放射線醫學影像。該技術主要通過單一軸面的X射線旋轉照射人體，由於不同的組織對X射線的吸收不同，可以用電腦的三維技術重建出斷層面影像。經由窗寬、窗位處理，可以得到相應組織的斷層影像。將斷層影像層層堆疊，即可形成立體影像。

解釋二(英)：Computed tomography (CT) is a medical imaging method employing tomography created by computer processing.[1] 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 Austinwhich uses a CT scanner to study biological and paleontological specimens.

解釋二(中)：計算機斷層掃描（CT）是一種醫學斷層成像方法採用計算機處理造成的。數字幾何處理是用於生成三維圖像的內部對象從一個大的一系列二維 X射線圖像採取圍繞一個軸旋轉。

CT產生量的數據，可以被操縱，通過一個過程稱為“窗口”，以顯示不同的身體結構，根據他們的能力阻止X-ray/Röntgen光束。儘管歷史上產生的圖像在軸向或橫向平面，垂直於長軸身體，現代掃描器讓本書的數據進行格式化各種飛機，甚至是體積（三維）申述結構。雖然最常見的在醫藥，CT是也用在其他領域，如材料的無損檢測。另一個例子是DigiMorph項目在德克薩斯大學奧斯汀分校的使用CT掃描儀，研究生物和古生物標本。
