What Is Body Image Disturbance?

Imaging not only expands the scope of the human body's examination and improves the level of diagnosis, but also can treat some diseases. In this way, the work content of this discipline has been greatly expanded, and it has become an important pillar in medical work. Shortly after Wilhelm Conrad Rontgen discovered X-rays in 1895, in medicine, X-rays were used to examine human bodies and diagnose diseases, forming a new discipline of diagnostic radiology and establishing medical imaging medicalimageology). To date, radiological diagnostics is still the main content of medical imaging, and its application is widespread.

Videography

From the 1950s to the 1960s, the use of ultrasound and magnetic resonance scanning for human examination began to appear.

X-ray images are composed of images with different gray levels from black to white. These different grayscale images reflect the anatomy and structure of human tissues.

The patient lies on the examination table, positions it, selects the thickness of the slice and the scanning range, and makes the scanning part extend into the hole of the scanning frame to perform scanning. Most of them use cross-section scanning, and the layer thickness is 5 or 10mm. For special needs, a thin layer can be used, such as 2mm. The patient should remain motionless and stop breathing on chest and abdomen scans. Because slight movements or activities can cause artifacts and affect image quality.

CT check points

When observing and analyzing, you should first understand the technical conditions of the scan.

CT diagnosis has been widely used in clinic because of its special diagnostic value. However, CT equipment is relatively expensive, and the inspection cost is high. The inspection and diagnostic value of some parts, especially

The new situation of medical imaging development is constantly developing. In the new century, the globalization and sustainable development of knowledge and economy will become the mainstream of human social and economic development. Among them, life sciences and information science will be the main disciplines of scientific development across the century.

Modern medicine is evidence-based medicine, and medical imaging includes a variety of imaging examinations and treatment methods, which has become the largest source of evidence in clinical practice. It is worth mentioning that the development trend of medical imaging is the fusion and optimization of multiple imaging inspection methods. In addition, the medical imaging profession also needs information exchange and mutual integration.

The development of medical imaging is manifested in several aspects. Image digitization is the basic need for image development. Networking of equipment can improve the use and guarantee efficiency of equipment. Comprehensive diagnostics can optimize multiple image examinations and improve the accuracy of diagnosis. Grouping systems It can be more closely integrated with the clinic to fully utilize the advantages of comprehensive imaging; and the filmless archiving is to realize digital management.

The Necessity of Digital Image Construction

The digitization of the imaging department is an important part of the digital construction of the hospital. Its main advantages are as follows: it can simplify and accurately manage the department, provide a new way of reading digital images; reduce tedious file management; retain image data intact; Teaching and resolving possible legal disputes in the future are the best guarantees; reducing the amount of film used, saving camera and processor medicine.

The digitization of the imaging department is still a requirement of the clinical department. The image information is used in the clinic. During the clinical diagnosis and treatment, especially the emergency department and the operating room, which are in urgent need of the image, can quickly obtain the image data, improve the emergency and emergency level, significantly speed up the medical procedures, and better serve the patients. service.

In addition, the digitization of the imaging department is also a requirement for the development of the discipline. The digitization of image data is the prerequisite for image resource sharing and remote consultation. Through digitization, informationization, and networkization, the hospital can modernize its management work. In addition, digitization also provides medical staff with a large number of image data and materials that can be called at will, thereby generating greater social and economic benefits.

Digital Grand Imaging

Hospital digital construction is the product of the combination of electronics industry, computer technology and medicine. It is the inevitable development of imaging and the inevitable development of the whole science. Science has developed to this day, and electronic information and computer technology have been fully developed. The combination of them is the origin and foundation of the development of digital imaging. The main advantages of digital imaging are: it can convert simulated dead images into reusable or data, and further convert two-dimensional planar images into multi-dimensional stereo images; it can make quantitative image diagnosis possible; it has completely changed traditional medicine Image viewing, usage, storage and management methods.

Digital imagery turns past analog images into reusable data. In the past, the hospital gave the patient an X-ray film. It could only record the image of the patient under the current conditions. It could not see new things through it. And digitization turns the image into a kind of living data, which can turn the past two-dimensional flat image into a multi-dimensional stereo image, from the past only one plane and length and width to a length, width, height, or front, back, left, Up and down stereo image.

Due to the different functions introduced, medical imaging itself not only reflects the three-dimensional structure, but also includes elements such as time and resolution. In the change of function, we call it a four-dimensional image. In the past, we could only make qualitative judgments. There was no precise data to make quantitative judgments on patient films. With digital imaging, we can make accurate measurements of these. For example, by measuring the CT value of the patient's image, the tissue type of the lesion can be clearly obtained, so as to make a diagnosis.

On the basis of the digital platform, with the help of digital images, we can clearly show the entire blood vessel running, and even the fine blood vessel branches at the end of the organ, which is helpful for us to explore the pathological changes of blood vessels.

Large image and all digital standards

The standard for all digital images should be expressed as follows: all radiology inspection equipment (XR, CT, MRI, DSA, etc.) must be digitized; all imaging inspection methods that display the general morphological information of human organs and tissues as diagnostic purposes , NM) must be digitized; all information (applications, reports, etc.) related to imaging diagnosis and treatment in the hospital must be digitized.

The standard of large images is mainly composed of modern medical imaging disciplines that combine both diagnosis and treatment, including radiological (including XR, CT, MRI, DSA), ultrasound, nuclear medicine and other diagnostic imaging technologies and interventional treatment technologies. At the same time in the radiology department to achieve system grouping rather than equipment division. The so-called system grouping mainly refers to the division of the system of modern medical imaging in accordance with the settings of clinical disciplines in the grouping, which can simultaneously synthesize all the data of radiation, ultrasound, nuclear medicine, etc., which can also provide more Multi-foundation. This is the big image, so that the entire digital image data can be used with each other.

The significance of a fully digital image

The hospital's realization of full digitalization has laid the foundation for the development of medical imaging such as image regulation, viewing mode, diagnostic quality, transmission and archiving, information exchange, and management.

It provides the best and convenient mode for clinical reference and retrieval of images. At the same time, remote consultation solves the problem of people seeking medical treatment in remote areas, and promotes the development of medical imaging teaching and scientific research. In addition, all digitalization has improved the platform of medical imaging, and the combination with biotechnology, genetic engineering and medical bioengineering will accelerate the update of prevention and diagnosis and treatment technology (PET-CT, MRI-CT).

Large imaging is conducive to the selection and optimization of information and complementary information among various imaging technologies in the hospital. It can achieve a close combination between diagnosis and treatment, which greatly promotes the training of personnel and the development of disciplines in medical imaging. Application for multi-level, high-level comprehensive imaging research projects.

The all-digital large-scale imaging can achieve the effect of 1 + 12, which is a complete reform of the way of viewing, using, storing and managing medical images.

Digital imaging can completely change the perspective of traditional medical imaging. The traditional viewing is generally the fluorescent screen perspective or film viewing, and we have many methods. With the help of digital images, we have new treatments in the use of image data, including storage management methods.

Digital imaging can bring us endless benefits. Digital construction can first meet the needs of the department, simplify the management of the department, reduce the labor intensity of the doctor, and retain the patient's original consultation data, so that the doctor can make the diagnosis more finely and make Research and teaching are of great help, and can also resolve legal disputes that may occur in the future.

The development of medical imaging has made doctors have greater initiative in image review and image quality control. What's more, it has changed the key paradigms of doctors' work. In the past, doctors looked at the patient's CT films one by one. Now, when scanning a patient's image, there are 1,000 images. One day, 10,000 images will be generated. The doctor cannot watch these films completely. With the help of medical imaging, these films can be post-processed to fuse them into a three-dimensional image so that doctors can look at the three-dimensional image first. Digital imaging has laid a foundation for diagnostic quality, graphic control, transmission and archiving, information exchange, and department management. It provides an optimal and convenient mode for clinical reference images, and solves many difficult and marginal problems.

It must be pointed out that the development of information technology has indeed provided us with great convenience, and has also promoted the development of medical imaging and teaching and research work. Its combination with biotechnology, genetic engineering and medical engineering will accelerate the update of new technologies.

Challenges of Digital Big Imaging

Due to historical reasons, most hospitals in China currently have independent departments of radiology, ultrasound, and nuclear medicine, and even XR, CT, and MRI in the radiology department are fighting each other. Many hospitals are constrained by old ideas, and there are misunderstandings in implementation. The ideal step is in place. They only see the update of medical equipment and ignore the importance of all digitalization of hospital equipment. Therefore, hospitals at all levels should improve their understanding of digital big imaging, update their concepts, and actively promote their application in hospitals.
