1. Image is the material representation of human visual perception. Images can be obtained by optical equipment, such as cameras, mirrors, telescopes, microscopes, etc.; they can also be created artificially, such as hand-painted images. Image is also a visual symbol. Through professionally designed images, you can develop a visual language for communication between people, and you can also learn about a large number of two-dimensional paintings, three-dimensional sculptures and architecture in world art.
2. Image is also called image. Refers to the imaging method of non-photographic imaging sensors, which is essentially an extension of photographic images. Photos usually refer to optical photography and are recorded on photosensitive film, which is passive remote sensing imaging. Images can receive visible light, infrared, thermal infrared and microwave information from ground objects through optical-mechanical, optical-electronic or antenna scanning, and be recorded on magnetic tape or on photosensitive film through electro-optical conversion.
3. Imaging not only expands the scope of human body examination and improves the level of diagnosis, but also can treat certain diseases. In this way, the work content of this discipline has been greatly expanded and it has become an important pillar in medical work.
4. Soon after Wilhelm Conrad Rontgen discovered X-rays in 1895, X-rays were used in medicine to examine the human body and diagnose diseases, forming a new field of diagnostic radiology. discipline and laid the foundation for medical imaging. To this day, diagnostic radiology is still the main content of medical imaging and is widely used.
