1, CT, that is, electronic computed tomography
CT is the use of precise collimation of X-ray beams, γ-rays, ultrasound, etc., with a very high sensitivity detector around a part of the human body for a cross-section of the scanning time is fast, the image is clear and so on, it can be used for a variety of diseases, according to the use of the ray can be divided into: X-ray CT (X-CT), ultrasound CT (UCT), and γ-ray CT (γ-CT), and so on. (X-CT), ultrasound CT (UCT) and γ-ray CT (γ-CT).
2, CR, that is, computerized radiography system
Computerized radiography refers to the use of light-excited storage fluorophore as a detector of the X-ray projection imaging method, but also refers to the use of this imaging method of medical imaging equipment.
3, DR, that is, direct digital radiography system
DR refers to a new technology in the computer-controlled direct digital radiography, that is, the use of amorphous silicon flat-panel detector to penetrate the body of the X-ray information into digital signals, and by the computer to reconstruct the image and a series of post-processing of the image.
DR system mainly includes X-ray generator, direct conversion of flat-panel detector, system controller, image monitor. Detector, system controller, image monitor, image processing workstation and other components.
4, magnetic **** vibration
It is a revolution in medical imaging, biological tissues can be electromagnetic spectrum of short-wave components such as X-ray penetration, but can block the medium-wave components such as ultraviolet, infrared and long-wave. Human tissue allows the long-wave components such as radio waves generated by magnetic *** vibration to pass through, which is one of the basic conditions for magnetic *** vibration to be used in clinical applications.
5, DSA, that is, digital subtraction angiography technology
Digital subtraction angiography technology is a new X-ray imaging system, is a combination of conventional angiography and electronic computer image processing technology. The images processed by DSA give a clearer image of the blood vessels and are safer when performing interventional procedures.
