The application of ultrasound imaging diagnostic technology in medicine began in the middle of the last century. At the beginning, only the thickness of the isolated organs was detected by the A-type ultrasonic instrument, and some clinical disease diagnosis was explored; then the M-type ultrasonic instrument was used to detect normal people and The heart of patients with rheumatic heart disease; until the early 1970s, B-mode ultrasound imaging technology, which can show changes in the morphology and structure of organs and lesions, was used in clinical practice. Page. In the mid-1980s, the color Doppler ultrasound diagnostic instrument came out. Because it can display the dual information of the morphological structure and hemodynamic changes of organs and lesions, it has advanced the level of ultrasound imaging diagnosis technology. Until the wide application of computer digital technology in the 1990s, the successful research of medical ultrasound 3D imaging technology enabled ultrasound imaging diagnosis technology to enter a higher level and a new stage of development. In other words, from the end of the last century to the beginning of this century, the development of ultrasound imaging diagnostic technology is amazing, and it has made many major technological breakthroughs. Throughout the development process of ultrasound imaging diagnostic technology, it is a development process from “point” (A-mode ultrasound) → “line” (M-mode ultrasound) → “surface” (two-dimensional ultrasound) → “body” (three-dimensional ultrasound) ; It is a development process from one-dimensional array to two-dimensional array to three-dimensional array; it is a development process from static imaging to real-time dynamic imaging; it is a development process from single-parameter diagnostic technology to multi-parameter diagnostic technology; It is also a process of development from anatomical structure morphological imaging to anatomical structure functional imaging, metabolic imaging, enzyme and receptor and gene expression imaging fusion molecular imaging.
