History of images

What is the development history of medical imaging? Since German physicist wilhelm konrad rontgen discovered X-ray (commonly known as X-ray) in 1895, medical imaging has turned a new page. Before that, doctors had to rely on palpation except direct incision, but both methods had certain risks.

1978, at the annual meeting of radiology, one is called g.n.

Engineers in Hounsfield published the results of computed tomography. This is the most important breakthrough in the field of radiation medicine after the discovery of X-rays, and it is also one of the great achievements of science and technology in the 20th century.

Hunsfield and Cormac won the 1979 Nobel Prize in Physiology and Medicine for their epoch-making contributions to radiation medicine. The development of ultrasonic imaging equipment benefited from the development of radar and sonar technology in World War II.

In 1950s, a simple A-type ultrasonic diagnostic instrument began to be used in clinic. In 1970s, the B-type instrument which can provide cross-section dynamics came out.

Color flow chart (CFM) came out in the early 1980s, and it is a high-grade ultrasonic diagnostic instrument currently used in clinic. 1945, American scholars first discovered the phenomenon of magnetic vibration, and then the science of nuclear magnetic resonance spectroscopy came into being.

In the late 1970s, human magnetic resonance imaging was successful. In 2003, the Nobel Prize or Medical Prize was awarded to Paul Burke, an American scientist who made outstanding contributions to the research of magnetic resonance imaging.

History of medical imaging Medical imaging is an important part of medical science, with a history of 100 years. It is not only closely related to clinical disciplines, but also 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 is very rapid, the medical imaging equipment is constantly updated, and the inspection technology is constantly improved, which has raised the effect of medical imaging diagnosis and interventional therapy to a new level, effectively promoted the development of clinical medicine and become an important pillar in medical work. Therefore, medical imaging is also an important clinical medicine and a compulsory course for medical college students.

What is the historical evolution of clinical medical imaging? Roentgen X-ray was discovered by wilhelm konrad rontgen in 1895. In medicine, X-ray is used to examine human body and diagnose diseases, which forms a new discipline of diagnostic radiology and lays the foundation for clinical medical imaging.

Radiodiagnostics is still the main content of clinical medical imaging and is widely used. From 1950s to 1960s, ultrasound and radionuclide scanning were used in human body examination, and ultrasonic imaging (USG) and γ scintillation scanning appeared.

In 1970s and 1980s, X-ray put tomography (CT), magic resonance imaging (MRI) and emission computed tomography (EMT) appeared one after another. ECT), such as single photon emission tomography (SPECT) and positron emission tomography (PET). In this way, only after 100 years, diagnostic imaging including X-ray diagnosis was formed.

Although the imaging principles and methods of various imaging technologies are different, the diagnostic value and limit are also different, but they all image the internal structures and organs of the human body, so as to understand the anatomical and physiological functions and pathological changes of the human body and achieve the purpose of diagnosis; All belong to the category of visual diagnosis of living organs and are special diagnostic methods. Interventional radiology, which rose rapidly in the 1970s, is to collect specimens under image monitoring or treat some diseases on the basis of image diagnosis, making image diagnosis a brand-new situation in clinical medical imaging.

Clinical medical imaging not only expands the scope of human examination and improves the diagnostic level, but also can treat some diseases. This has greatly expanded the work content of this discipline and become an important pillar in medical work.

China has made great progress in clinical medical imaging. The professional team continues to grow, and all medical units have established imaging departments.

Modern imaging equipment, in addition to conventional imaging diagnostic equipment, advanced equipment such as USG, Ct, SPECT and even MRI have been applied in larger medical units and accumulated rich experience. There are many kinds of books and periodicals for clinical medical imaging specialty, which have played an active role in medicine, teaching, scientific research, professional personnel training and academic exchanges.

As an academic group, the National Radiological Society and local chapters have effectively promoted academic exchanges at home and abroad. Imaging equipment, including conventional and advanced equipment, such as CT and MRI equipment and such as film, developer, fixative and contrast agent.

China has been able to design, produce or assemble by itself.
