Application of medical imaging technology in medical imaging principle

The application of medical imaging technology in medical imaging principle is as follows:

(A) computer X-ray photography technology analysis

In the practical application process, the main working principle of X-ray photography technology is: first, the image version will receive the X-ray latent image completely and form a certain image after passing through the human body, and then use the laser scanner and data converter to convert various types of signals into images. Compared with traditional X-ray photography, the application of this technology has good advantages. On the one hand, it can reduce the amount of X-ray radiation to patients, and one photography can collect more information. ?

On the other hand, in the actual processing process, the exposure width is large, the capacity is large, and the dynamic range of density is large, which can improve the effect of photography technology, improve the definition of images, reduce the influence of various factors, and reduce the number of remakes.

(2) Computer tomography analysis.

In the practical application process, the main principle is: using X-ray to scan the human body layer by layer, scanning a certain area or range according to the relevant physical examination requirements, and then generating diagnostic information in the computer, and comprehensively processing the data or suggestions for processing it in the case of cross-sectional anatomical map.

Secondly, in the actual use process, it has higher advantages than the traditional CT, which can speed up the scanning work, obtain high image resolution, expand the data scanning collection range, improve work efficiency, and avoid the gradual improvement of reliability and effectiveness under the condition of increasing technical improvement.

(3) Analysis of magnetic resonance imaging technology

This technology, also known as nuclear resonance technology, deals with nuclei related to human tissues. Under the action of external magnetic field, nuclear magnetic resonance can be generated to achieve the purpose of imaging. The principle of this technology is: scan the diseased part of the patient, parallelize it while maintaining the long axis direction and static magnetic field, and then process the part to be detected with pulsed RF magnetic field. Finally, the computer will obtain relevant signals to form two-dimensional or three-dimensional images.
