What is medical imaging?

Medical imaging refers to the technology and processing process of obtaining the internal tissue image of human body or a certain part of human body in a non-invasive way for medical treatment or medical research. It includes the following two relatively independent research directions: medical imaging system and medical image processing. The former refers to the imaging process, including the study of imaging mechanism, imaging equipment, imaging system analysis and other issues; The latter refers to the further processing of the obtained image, the purpose of which is either to restore the original unclear image, or to highlight some characteristic information in the image, or to classify the image in a pattern, etc.

As a science, medical imaging belongs to biological imaging, including image diagnosis, radiology, endoscope, medical thermal imaging technology, medical photography and microscope. In addition, although technologies including EEG and brain magnetic resonance imaging focus on measurement and recording, and there is no image display, the generated data can be regarded as another form of medical images because of its positioning characteristics (that is, it contains location information).
