Medical imaging paradigm

Medical imaging refers to the technology and processing process of obtaining the internal tissue image of human body or a certain part of human body in a non-invasive way for medical treatment or medical research. Below, I will share my paper on medical imaging with you, hoping to help you!

Digital image processing technology is a kind of network processing technology developed on the basis of current digital development, which can realize more realistic picture display. In medicine, with the infiltration of digital image processing technology, digital images show related diseases, and the related data on the screen are processed by processing technology. This kind of medical treatment can greatly improve the cure rate of related diseases and achieve more accurate treatment. In medicine, medical images are mainly used in the following aspects, including CT (Computed Tomography), PET (Positron Emission Tomography), MRI (Magnetic Resonance Imaging) and UI (Ultrasound Imaging). On the basis of technical development, the application scope of digital image processing technology will gradually expand and the application effect will be further improved.

1 Application of Key Technologies in Digital Image Processing

The processing of digital images in medical images is usually to convert digital images into relevant data, and analyze the symptoms of patients according to the results presented by relevant data. There are some key technologies in digital image processing, which directly affect the whole medical treatment and examination.

1. 1 image acquisition

Image acquisition, as its name implies, is to sort out the relevant data of doctors and patients. When digital image detection is carried out, the obtained related images are processed in the form of data after computer conversion, and finally the processing results are presented. Computer images are displayed in digital form through photoelectric conversion, and digital image processing technology can also save the analysis results as the basis for medical diagnosis [1].

1.2 image processing

After using digital images to obtain related images, it is necessary to compress and encode the images, sort out all running data, compress related data, and process related codes, such as model-based encoding and neural network encoding.

1.3 image recognition and reconstruction

After image restoration, transform the image, segment the related image after image analysis, and measure the regional characteristics of the image. Finally, image equipment and presentation are realized, and image registration is carried out after image reconstruction.

2 Digital image processing technology in medical images

2. 1 digital image processing technology is used for adjuvant therapy.

At present, medical images include computerized X-ray tomography, positron emission tomography, nuclear magnetic resonance imaging and ultrasound images. In medical treatment, geometric patterns can be presented according to the formation of relevant data, such as 3D, which can be used to restore various tissues of the body, to realize the enlarged observation of small parts, to realize the quantitative understanding and more detailed observation of diseases by doctors, and to provide help for the next medical treatment. For example, in the treatment of magnetic resonance imaging, a certain magnetic field is set first, and the hydrogen nucleus in the body is stimulated by radio frequency pulses, so that it generates * * * vibration during operation, which promotes the absorption capacity of the body and helps to find out where the disease is [2].

2.2 Improve the curative effect of radiotherapy

In medical treatment, digital image processing technology can be used to observe and treat the affected area, which is common in radiotherapy of tumor or cancer focus. Before treatment, we must first locate the patient's position. After accurate positioning, the treatment plan should be comprehensively planned with the help of digital image processing technology, and the affected part should be treated on this basis. For example, in the treatment of tumors, cancers and other lesions, digital images are used to check the physical condition outside the lesions and reduce the risk of surgery.

2.3 Deepen the understanding of brain tissue and its function.

Brain tissue is the core of human function, and there are many complex structures in brain tissue. Therefore, in order to realize the functional understanding of brain tissue, it is necessary to observe brain tissue in all directions and explore its various organizational structures in depth. In recent years, with the improvement of medical technology, digital image processing technology has been applied to medicine. Digital image processing technology can realize all-round observation of brain tissue through cerebral cortex, and finally present the running state of various mechanisms in brain tissue in a three-dimensional way [3]. For example, functional magnetic resonance imaging (FMRI) can detect the activity of cerebral cortex and track the changes of signals in real time. Its high-definition time resolution provides a lot of help for contemporary medical care.

2.4 The digital anatomy function is realized.

Digital anatomy is virtual anatomy. This anatomical behavior needs to rely on high technology from mechanics, vision and other aspects. Through the establishment of virtual human resources, we can analyze the organizational structure of human body, realize the anatomy of virtual human, increase the understanding of human body and truly restore the anatomical knowledge. This method has an important influence on medical teaching and anatomical research.

3 Conclusion theory

To sum up, digital image processing technology has important application value in medical imaging. The development of digital image processing technology provides a medical technology platform and application space for the development of digital image processing technology. This combination is not only the requirement of social development, but also the trend of the times.
