Application of medical imaging technology in medical imaging principle

Medical imaging technology originally refers to radiation imaging technology, such as x-ray, meta-line and so on. X-ray imaging mainly depends on the penetrating power of ray wavelength, and is mainly used to observe human organs and tissues, such as bones, shapes, positions, properties, metal foreign bodies and so on. If human bones or organs are diseased or deformed, you can scan the relevant parts with rays and then image them on film. From the imaging of the film, we can see the lesions in the body. Today's X-ray technology is more perfect and advanced than before. Natural tissues and organs that were previously difficult to image, such as blood vessels, heart and bladder, can now be imaged by X-rays. At present, X-ray photography and fluoroscopy equipment mostly adopts multi-host system, and then it can be used together with various auxiliary equipment such as photography and diagnostic bed. Combined with advanced computer control and image processing system, X-ray technology can complete some special tasks and functional tests.

Secondly, computer tomography technology.

Computerized tomography, also known as CT, mainly includes X-ray tomography device and computer system. CT mainly works by using the different properties of X-rays absorbed by human tissues. It can divide a specific layer of human body into many cubes, and X-ray can obtain clinical diagnosis information by scanning these cubes. Computed tomography mainly scans a certain part or area of the human body. Then the diagnosis data or treatment measures are formed in the connected computer. Computed tomography has very high accuracy in scanning the cross section of tissue. The biggest difference between computed tomography and radiological imaging is that the former can not only qualitatively monitor the progress of human organs, but also provide accurate inspection data information. Moreover, the scanning speed of computerized tomography is very fast, and the final imaging resolution is particularly high. The scanning area and working area of photography technology are also related to the efficiency of photographic imaging.

Third, nuclear magnetic resonance imaging technology

Magnetic resonance imaging is a kind of magnetic resonance imaging closely related to human body. Its working principle is that when the human body is stimulated by external fixed pulses, the hydrogen in the human body will produce magnetic vibration. Once the magnetic field disappears, protons will send out signals and form images, sir. Magnetic resonance imaging can clearly show the fine structure of heart, atrium and other organs, which also provides accurate treatment basis for various cardiovascular diseases and heart diseases.
