Since the discovery of X-rays (commonly known as X-rays) by the German physicist Wilhelm Conrad R?ntgen in 1895, a whole new page of medical imaging has been opened. Prior to this, physicians who wanted to know what was going on inside a patient's body could only do so by palpation, in addition to direct dissection, but both of these methods had certain risks.
In 1978, at the Annual Meeting of Radiology, an engineer named G.N.
Hounsfield announced the results of computed tomography. This was the most important breakthrough in radiology since the discovery of X-rays, and one of the great achievements of science and technology in the 20th century.
Hounsfield and Cormack were awarded the 1979 Nobel Prize in Physiology and Medicine for their groundbreaking contributions to radiation medicine. The development of ultrasound imaging equipment was aided by the development of radar and sonar technology during World War II.
In the 1950s, simple A-mode diagnostic ultrasound machines began to be used in clinical practice. By the 1970s, B-mode instruments were introduced that provided cross-sectional dynamics.
Ultrasound colorflowmapping (CFM), introduced in the early 1980s, is a high-grade ultrasound diagnostic instrument currently in clinical use. In 1945, American scholars first discovered the phenomenon of magnetic **** vibration, from which arose the science of nuclear magnetic **** vibration spectroscopy.
In the late 70s, the human body of the magnetic **** vibration imaging success. 2003, the Nobel Prize for victory or medicine awarded to the magnetic **** vibration imaging research has made outstanding contributions to the American scientists PaulC.

History of Medical ImagingMedical imaging is an important part of medical science, and has a history of more than 100 years. It is both closely related to clinical disciplines and based on basic disciplines such as human anatomy, physiology, pathophysiology, and physics. In addition, the integration of computer science has added vitality and enriched the content.
In recent years, the development of medical imaging has been very rapid, medical imaging equipment is constantly updated, and inspection technology is constantly improved, so that the effect of medical imaging diagnosis and interventional therapy has been improved to a new level, and vigorously promote the development of clinical medicine, and become an important pillar of medical work. Therefore, medical imaging is also an important clinical medical science, is a compulsory course for medical school students.
What is the history of clinical medical imagingR?ntgen rays since R?ntgen (Wilhelm Conrad rontgen) in 1895 after the discovery of X-rays soon after the medical, X-rays are used to check the human body, disease diagnosis, the formation of a diagnostic radiology (diagnostic radiology) of the new disciplines and laid the groundwork for the development of clinical medical imaging (medical imaging).
Diagnostic radiology is a new discipline of radiology, and lays the foundation for clinical medical imaging (medical imageology).
Diagnostic radiology is still the main content of clinical medical imaging, and its application is widespread. 50's to 60's began to apply ultrasound and nuclide scanning for human body examination, the emergence of ultrasonography (ultrasonography, USG) and gamma scintigraphy (γ-scintigraphy).
In the 1970s and 1980s, X-ray computed tomography (X-ray puted tomography, X-ray CT, or CT), magnetic resonance imaging (MRI), and emission puted tomography (ECT) were introduced. ECT) such as single photon emission puted tomography (SPECT) and positron emission tomography (PET). In this way, diagnostic imaging, including X-ray diagnostics, has been developed in only 100 years.
Although the imaging principles and methods of various imaging technologies are different, and the diagnostic value and limitations are also different, they all make the internal structure of the human body and organs to form an image, so as to understand the anatomy and physiological function of the human body as well as the pathological changes, in order to achieve the diagnostic purpose; they are all belonging to the scope of the visual diagnosis of the living organ, which is a special diagnostic method. In the 1970s, the rapid emergence of interventional radiology, that is, in the image under the supervision of the collection of specimens or on the basis of image diagnosis, the treatment of certain diseases, diagnostic imaging for the development of clinical medical imaging of a new situation.
Clinical medical imaging not only expands the scope of human examination and improves the level of diagnosis, but also allows for the treatment of certain diseases. In this way, the work of this discipline has been greatly expanded and has become an important pillar of medical work.
China's clinical medical imaging has developed greatly. The professional team is growing, and there are imaging departments in all medical units.
Modern imaging equipment, in addition to conventional diagnostic imaging equipment, USG, Ct, SPECT, and even MRI and other advanced equipment has been applied in the larger medical units, and has accumulated a relatively rich experience. Clinical medical imaging ground specializing in a wide range of books and journals, in medicine, teaching, research, training professionals and academic exchanges play a positive role.
As an academic organization, the National Society of Radiology and and local chapters, strongly promote domestic and international academic exchanges.
China has been able to design, manufacture or assemble its own.
