In the new century, knowledge and economic globalization and sustainable development will become the mainstream of human social and economic development. Among them, life science and information science 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 a variety of imaging means of choice. 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 use of equipment and security efficiency; diagnostic synthesis can optimize a variety of imaging tests to improve diagnostic accuracy; grouping systematic can be more closely integrated with the clinical and give full play to the advantages of integrated imaging; and archiving without film is to achieve digital management.
Necessity of fully digital imaging construction
Digitalization 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 precise departmental management, provide a new way of digital image reading; reduce the cumbersome archive management; and keep the image data intact, which is the best guarantee for scientific research, teaching and solving possible legal disputes in the future; Reduce film usage and save camera and film developer potion.
Digitization of the imaging department is still the needs 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, improve the level of emergency, first aid, significantly speed up the medical procedures, and better service for patients.
In addition, the digitization of the imaging department is also the demand for the development of the discipline, the digitization of imaging data is the premise of the imaging resources **** enjoyment and remote consultation, through the digitization, informatization, networking, hospitals can realize the modernization of the management of the work. In addition, digitization also provides medical staff with a large number of image data and information that can be called at will, thus generating greater social and economic benefits.
Digital imaging
Hospital digital construction is the electronic industry, computer technology and medical combination of products, it is the development of imaging is inevitable, but also the development of the whole science is inevitable. Scientific development to today, electronic information, computer technology have been fully developed, the product of their combination is now the origin and foundation of the development of digital imaging. The main advantages of digital imaging performance: can be analog dead images into reusable or data, and further two-dimensional flat images into multi-dimensional three-dimensional images; can make quantitative diagnosis of the image possible; completely change the traditional medical image view, use, storage and management.
Digital imaging is the transformation of analog images into reusable data. In the past, hospitals gave patients an X-ray film, which could only record the patient's image under current conditions, and could not see new things through it. The digitalization 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 a 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 determinations, and there was no exact data to make quantitative determinations on the patient's film. Now, with the help of digitized images, we can make exact measurements of these. For example, by measuring the CT value of a patient's image, the type of tissue that is diseased can be clearly identified and a diagnosis can be made.
Based on the digital platform, with the help of digital imaging, we can clearly show the entire vascular pathway, and even see the microvascular branches at the end of the organ, which helps us to explore the vascular lesions.
The standard of big image and all-digital
The standard of all-digital image should be shown as follows: all examination equipments (XR, CT, MRI, DSA, etc.) in radiology department must be digitized; all the imaging means (BU, NM) which display the information on the general morphology of organs and tissues of the human body as the diagnostic purpose must be digitized; and all the information (application, diagnosis, treatment, etc.) related to the image of the 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 diagnosis and treatment of both 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 within 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 in accordance with the clinical disciplines of the setup, from the system on the division, so that can simultaneously synthesize all the information of radiology, ultrasound, nuclear medicine, etc., which can also provide more bases for the patient's diagnosis. This is the big image, so that the whole digital imaging information can be utilized with each other.
The significance of the all-digital big image
Hospitals to realize the all-digital for the development of medical imaging such as image regulation, viewing mode, diagnostic quality, transmission archiving, information exchange, and management has laid the foundation.
It provides the best and convenient mode for clinical reference to access images, while remote consultation solves the problem of people in remote areas, and promotes the development of medical imaging teaching and research work. 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, able to achieve close integration between diagnosis and treatment, greatly promoting the training of personnel and the development of the discipline of medical imaging, but also conducive to the declaration of national, multi-level, high-level comprehensive imaging research projects.
And the all-digital big imaging can play the effect of 1+1≥2, which is a thorough reform of the way of medical imaging visualization, use, storage and management.
Digital imaging can completely change the traditional medical imaging view. Traditional visualization is usually fluorescent screen fluoroscopy or look at the film, but now we have a variety of methods, with the help of digital imaging, we have a new handling of the use of image data, including the management of storage.
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 to retain the patient's original consultation data, thus enabling doctors to do diagnosis in a more refined, scientific research on the doctor, teaching are of great help, but also to solve the possible legal disputes in the future.
The development of medical imaging has enabled doctors to take greater initiative in image access and image quality control. And it has also led to a change in the critical paradigm of a doctor's work. In the past, doctors used to look at a patient's CT films one by one, but nowadays, scanning a patient's image, there are 1,000 images, and a day will produce 10,000 images, so doctors can't thoroughly look at all these films at all. Now with the help of medical imaging, these films can be post-processed first, so that the fusion becomes 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 for clinical reference imaging and solves many difficult and marginal problems.
It must be pointed out that the development of information technology does provide us with great convenience and promotes medical imaging and teaching and research, and its combination with biotechnology, genetic engineering and medical engineering will accelerate the updating of new technologies.
The challenges of digital imaging
For historical reasons, the vast majority of hospitals in China's radiology, ultrasound, and nuclear medicine are independent departments, and even XR, CT, and MRI within the Department of Radiology are working separately. Many hospitals are bound by old concepts, there are misunderstandings in the implementation of the ideal one step at a time, 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 the understanding of digital macroimaging, update the concept, and actively promote its application in the hospital.
