Medical magnetic resonance imaging equipment is a kind of medical equipment that uses the principle of magnetic resonance to image the internal tissues and organs of the human body to help doctors make medical diagnosis.
Imaging principle
Magnetic resonance imaging is an image detection technology that uses the principle of nuclear magnetic resonance. It uses the characteristics of nuclear spin motion. In an external magnetic field, a signal is generated after a radio frequency pulse, which is detected by a detector and then input into a computer. The image is displayed on the visualization device after data processing conversion. [1]
Human tissue cells are very rich in water. Different tissues have different water content. If its distribution information can be detected, a relatively complete image of the internal structure of the human body can be drawn. Nuclear magnetic resonance imaging technology is By identifying the distribution of hydrogen atom signals in water molecules, it is a technology to infer the distribution of water molecules in the human body, and then detect the internal structure of the human body.
