What is computed tomography?

computed tomography (CT), or computed tomography, is an examination of image diagnostics. This technique was once called Computed Axial Tomography.

X-ray tomography is a three-dimensional radiological medical image reconstructed by digital geometry processing. This technology mainly irradiates the human body through the rotation of X-rays in a single axial plane. Because different tissues have different absorption of X-rays, the three-dimensional technology of the computer can be used to reconstruct the tomographic images. Through the processing of window width and window level, the tomographic images of the corresponding tissues can be obtained. A stereoscopic image can be formed by stacking the fault images layer by layer.

X-ray tomography is a three-dimensional radiological medical image reconstructed by digital geometry processing. This technology mainly irradiates the human body by rotating X-rays on a single axial plane. Because different biological tissues have different absorption power (or Radiodensity) to X-rays, the computer's three-dimensional technology can be used to reconstruct the tomographic image, and the relative gray-scale image can be obtained through window value and window level processing. If the images are stacked with computer software, a three-dimensional image can be formed.
