Feb 25, 2021 · The range of length and timescales that can be imaged non-destructively by X-ray computed tomography (CT) makes it a unique tool for acquiring three-dimensional (3D) movies (sometimes called 4D...

X射线计算机断层成像（X-Ray Computed Tomography，简称X-CT）是一种利用数位几何处理后重建的三维放射线医学影像。 该技术主要通过单一轴面的X射线旋转照射人体，由于不同的组织对X射线的吸收能力（或称阻射率）不同，可以用电脑的三维技术重建出断层面影像。

A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.

The term “computed tomography,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images, or “slices.”

X-ray computed tomography (CT) can reveal the internal details of objects in three dimensions non-destructively. In this Primer, we outline the basic principles of CT and describe the ways in which a CT scan can be acquired using X-ray tubes and synchrotron sources, including the different possible contrast modes that can be exploited.

Dec 6, 2024 · Computed tomography (CT) scanners are essential for modern imaging but require around 600 projections from various angles. We present x-ray–induced acoustic computed tomography (XACT), a method that uses radiation-induced acoustic waves for three-dimensional (3D) x-ray imaging.

计算机断层扫描 （computed tomography scan，CT scan）或 计算机体层成像 （CT），简称 CT扫描，是一種 影像診斷學 的技术或检查；广义上，是指利用精确准直的成像媒介（如X射线、γ射线、超声波等）与高灵敏度的探测器，围绕人体或物体的某一部位采集数据，并根据需要重建出断面影像的一种成像方法。 计算机断层扫描现在多採狭义上定义，是特指以 X线束 从多个方向沿着人体或物体某一选定断层层面进行照射，测定透过的X线量，数字化后经过计算机处理， …

Dec 25, 2024 · Computed tomography (CT), also known as, especially in the older literature and textbooks, computerized axial tomography (CAT), is an imaging modality that uses x-rays to build cross-sectional images ("slices") of the body.

Although also based on the variable absorption of x rays by different tissues, computed tomography (CT) imaging, also known as "CAT scanning" (Computerized Axial Tomography), provides a...

Computed tomography (CT), sometimes called "computerized tomography" or "computed axial tomography" (CAT), is a noninvasive medical examination or procedure that uses specialized X-ray...
