The majors that can be applied for postgraduate entrance examinations in medical imaging include: general surgery, orthopedic surgery, burn surgery, neurosurgery, plastic surgery, clinical medicine, imaging medicine, internal medicine, pediatrics and neurology.

Medical imaging mainly studies the recording, processing and interpretation of information on the appearance, structure, tissue, organs and functions of the human body and animals. It can also be used in clinical diagnosis, pathological research, drug efficacy evaluation, etc., and has become one of the important pillars of clinical medicine. Medical imaging is also called silver halide imaging, because in the past, film (film) was imaged with the photosensitive material silver halide chemical photosensitive material.

Because medical imaging has the characteristics of high definition, high sensitivity, and non-invasiveness, it has been widely used in clinical practice. For example, image recording and processing through X-ray, film, digital display systems and other technical means can accurately diagnose and treat lesions in tumors, cardiovascular, nervous, skeletal and other systems.

With the rapid development of computer technology, the application fields of medical imaging are also constantly expanding, including digital image microprocessing, computer-aided diagnosis, three-dimensional imaging and other directions. Medical imaging includes two relatively independent research directions: medical imaging systems and medical image processing.

Applications of medical imaging:

Medical imaging can be used as a medical auxiliary method for diagnosis and treatment, and can also be used as a scientific research method in life science research. . Diagnosis mainly includes fluoroscopy, radiographs, CT, MRI, ultrasound, digital subtraction, angiography, etc. The main applications of treatment include interventional therapy, radiotherapy, etc.

Many technologies in medical imaging have been widely used in the scientific research industry. The development of medical imaging has benefited from the rapid advancement of modern computer technology. Its combination with image processing, computer vision, and pattern recognition technology has produced a new branch of computer technology - medical image processing.

Origin and development: In 1895, the German physicist R?ntgen discovered X-rays, which were soon used to examine diseases in the human body, and thus formed radiological diagnosis. In the past 30 years, CT, MRI, ultrasound and radionuclide imaging equipment have been continuously improved and perfected, and inspection techniques and methods have also been constantly innovated. Imaging diagnosis has developed from relying solely on morphological changes to integrating morphology, function, etc. .
