What are the characteristics of CT images compared with other images?

Through the collimation of X-ray collimation system, CT examination can obtain cross-sectional images that are not interfered by out-of-plane tissue structures. Compared with conventional X-ray tomography, the tomographic image obtained by CT has accurate thickness, clear image and high density resolution, and is not disturbed by out-of-plane structures. In addition, the cross-sectional images obtained by CT scanning can also be reconstructed by computer software to obtain cross-sectional images of multiple planes (such as coronal and sagittal planes) needed for diagnosis.

(2) High density resolution

In addition to magnetic resonance examination, CT examination has the highest density resolution compared with conventional image examination. XCTMR.com

(3) It can be used for quantitative analysis

CT examination can accurately measure the X-ray absorption attenuation value of each tissue, and make quantitative analysis through various calculations. J

(4) Computers can be used for various image processing.

With the help of computer and some image processing software, the shape and structure of the lesion can be analyzed. Spiral scanning can obtain high-quality three-dimensional images and multi-plane cross-sectional images.
