The new situation of the development of medical imaging has a continuous development.
In the new century, globalization of knowledge and economy and sustainable development will become the mainstream of human social and economic development.
Among them, life sciences and information sciences will be the main disciplines of scientific development across the century.
Modern medicine is evidence-based medicine, medical imaging encompasses a variety of imaging examination, treatment means, has become the largest source of clinical evidence.
It is worth mentioning that the trend in the development of medical imaging is the integration and optimization of multiple imaging methods.
In addition, there is a need for information exchange and mutual integration within the medical imaging specialty.
The development of medical imaging is manifested in several aspects, image digitization is the basic need for the development of imaging; equipment networking can improve the efficiency of the use of equipment and security; diagnostic synthesis can optimize a variety of imaging tests to improve diagnostic accuracy; grouping systematic can be more closely integrated with the clinic to give full play to the advantages of integrated imaging; and archiving without film is to achieve digital management.
The necessity of full digital construction of imaging
The digitization of the imaging department is an important part of the hospital's digital construction, and its main advantages are as follows: it can simplify and accurately manage the department, provide a new way of reading digital images; reduce the tedious archive management; and retain the image data intact, which is the best guarantee for scientific research, teaching, and solving the possible legal disputes in the future; Reduce the amount of film used, saving cameras, film developer potions.
The digitization of the imaging department is still a need of the clinical department.
Imaging information for clinical use, in the process of clinical diagnosis and treatment, in particular, can make the emergency department, operating room, these urgent need to see the image of the department to quickly get the image information, to improve the level of emergency, emergency, obviously speed up the medical procedures, and better service for patients.
In addition, the digitization of the imaging department is also a need for the development of the discipline, the digitization of imaging data is the premise of the imaging resources **** enjoyment and remote consultation, through the digitalization, informatization, networking, hospitals can realize the modernization of the management of the work.
In addition, digitization also provides healthcare professionals with a large amount of image data and information that can be called at will, thus generating greater social and economic benefits.
Digital imaging
The digital construction of hospitals is a product of the combination of the electronics industry, computer technology and medicine, which is the inevitable development of imaging, but also the inevitable development of the entire science.
The development of science today, electronic information, computer technology have been fully developed, and the product of their combination is now the origin and foundation of the development of digital imaging.
The main advantages of digital imaging are: the ability to analog dead images into reusable or data, and further two-dimensional flat images into multi-dimensional stereo images; can make quantitative diagnosis of the image possible; and completely change the traditional way of viewing, using, storing, and managing medical images.
Digital imaging is the transformation of analog images into reusable data.
In the past, hospitals gave patients an X-ray, which could only record the patient's image under current conditions, and could not see new things through it.
And digitization of the image into a living data, the past two-dimensional plane image into a multi-dimensional stereo image, from the past only a plane and the length and width into a length, width, height or before and after, left and right, up and down the three-dimensional image.
Because of the different functions introduced, medical imaging itself reflects not only the three-dimensional structure, but also 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 determinations, and we did not have the exact data to make quantitative determinations on the patient's slice.
Now, with digital imaging, we can make exact measurements of these.
For example, by measuring the CT value of a patient's image, it is possible to determine the type of tissue that is diseased and make a diagnosis.
On the basis of the digital platform, with the help of digital imaging, we can clearly show the entire vascular alignment and even see the microscopic vascular branches at the end of the organ, which facilitates our exploration of vascular lesions.
Standards for big images and full digitalization
The standards for full digitalization of images should be expressed as follows: all examination equipment in the radiology department (XR, CT, MRI, DSA, etc.) must be digitized; all the means of imaging (BU, NM) that display information about the gross morphology of human organs and tissues as a diagnostic purpose must be digitized; and all the information (application, treatment, etc.) related to the diagnostic and therapeutic information of the imaging department of a hospital must be digitized. All information related to diagnosis and treatment (applications, reports, etc.) must be digitized.
The standard of big image is mainly manifested in the composition of diagnostic and therapeutic modern medical imaging disciplines, including radiology (including XR, CT, MRI, DSA), ultrasound, nuclear medicine and other diagnostic imaging technology and interventional therapy technology.
At the same time in the radiology department to realize the system grouping rather than equipment division.
The so-called system grouping mainly refers to the modern medical imaging in the grouping according to the clinical disciplines of the setup, from the system on the division, so that at the same time can synthesize all the information of radiology, ultrasound, nuclear medicine, etc., which can also provide more basis for the diagnosis of the patient.
This is big imaging, so that the whole digital imaging can be utilized for each other.
The significance of all-digital big image
Hospitals to achieve all-digital for the development of medical imaging, such as image regulation, viewing mode, diagnostic quality, transmission archiving, information exchange, and management to lay the foundation.
It provides the best and most convenient mode for clinical reference images, and at the same time, remote consultation solves the problem of people in remote areas, and promotes the development of medical imaging teaching and research.
In addition, full digitalization enhances the platform of medical imaging, and the combination with biotechnology, genetic engineering and medical bioengineering will accelerate the updating of preventive and diagnostic technologies (PET-CT, MRI-CT).
Big Imaging is conducive to the optimization of the choice between various imaging technologies in hospitals, complementary information, and can achieve a close integration between diagnosis and treatment, which greatly promotes the cultivation of talents and the development of the discipline of medical imaging, and is also conducive to the declaration of national, multi-level, high-level comprehensive imaging research projects.
And all-digital big imaging can play the effect of 1 +1 ≥ 2, it is the medical image visualization, use, storage and management of the way the thorough reform.
Digital imaging can revolutionize the way traditional medical imaging is viewed.
Traditional visualization is usually fluoroscopy or looking at film, but now we have a variety of methods, and with digital imaging, we have a new way of dealing with the use of imaging data, including the way it is stored and managed.
Digital imaging can bring us endless benefits, digital construction can first meet the needs of the department, simplify the management of the department, can reduce the intensity of the doctor's labor, and retain the patient's original consultation data, so that the doctor to do diagnosis in a more delicate, the doctor's scientific research, teaching have a great deal of help, but also to solve the future may occur in the legal disputes.
The development of medical imaging has given doctors greater initiative in image access and image quality control.
Moreover, it has led to a change in the critical paradigm of the physician's work.
In the past, when doctors looked at a patient's CT films, they looked at them one by one, and now when they scan a patient's images, there are 1,000 images, and 10,000 images a day, and the doctor can't even look at them thoroughly.
Now, with the help of medical imaging, these films can be post-processed, so that they can be fused into a three-dimensional stereo, so that the doctor can first look at the stereo image.
Digital imaging lays the foundation for diagnostic quality, graphic control, transmission and archiving, exchange of information, and departmental management.
It provides an optimal and convenient mode of clinical reference imaging and solves many difficult and marginal problems.
It is important to point out that the development of information technology does provide us with great convenience and promote medical imaging and teaching and research, and its combination with biotechnology, genetic engineering, and medical engineering will accelerate the updating of new technologies.
Challenges to digital macro-imaging
For historical reasons, the vast majority of hospitals in China currently have independent departments for radiology, ultrasound, and nuclear medicine, and even XR, CT, and MRI within the radiology department work separately.
Many hospitals are bound by the old concepts, there are misunderstandings in the implementation, the ideal one step, only to see the update of medical equipment, ignoring the importance of the full digitalization of hospital equipment.
Therefore, hospitals at all levels should improve their understanding of digital macroimaging, update their concepts, and actively promote its application in hospitals.
