Sample Essay on Medical Imaging
Medical imaging is the technique and process of obtaining images of internal tissues of the human body, or a part of the human body, in a non-invasive manner for the purpose of medical treatment or medical research. Below, I am sharing a dissertation on medical imaging to help you!
Introduction
Digital image processing technology based on the current development of digitalization, and gradually derived from a network processing technology, digital image processing technology can be realized on the screen more realistic display. In medicine, with the penetration of digital image processing technology, digital images will be related to the disease presented, and through the processing technology on the screen related data processing, this medical means, can greatly enhance the cure rate of related diseases, to achieve more accurate treatment of the efficacy of treatment. In medicine, medical imaging is widely used in the following aspects, including CT (computed tomography), PET (positron emission tomography), MRI (magnetic resonance imaging) and UI (ultrasound imaging). Based on the technological development of digital image processing technology, the scope of its application will be gradually expanded, and the effectiveness of its application will be further enhanced.
1 The application of key technologies in digital image processing
The processing of digital images in medical imaging, usually the digital image into the relevant data, and for the results of the relevant data presented to analyze the patient's disease, in the digital image processing, there are certain key technologies, these key technologies directly affect the entire medical treatment and examination. These key technologies directly affect the entire medical treatment and examination.
1.1 Image acquisition
Image acquisition, as the name suggests, will be the doctor and patient data for the organization, in the digital image detection, the relevant images, after the acquisition of relevant images, through the transformation of the computer, the image in the form of data processing, and finally the results will be presented. In the computer ingested images, through the conversion of photoelectricity, in the form of digital presentation, digital image processing technology can also realize the results of the analysis as a basis for medical diagnosis, to be saved [1].
1.2 Image Processing
After the use of digital images to obtain relevant images, the need for image processing, such as compression processing, coding processing, all the running data to be organized, the data will be compressed, and will be related to the coding process, such as model-based coding, neural network coding processing.
1.3 Image Recognition and Reconstruction
After image restoration, the image is transformed, the relevant image is segmented after picture analysis, the regional features of the image are measured, and finally the image device and presentation are realized, and after the reconstruction of the image, the image alignment is performed.
2 Digital Image Processing Technology in Medical Imaging
2.1 Digital Image Processing Technology for Auxiliary Treatment
The current medical images include computed tomography, positron emission tomography (PET), nuclear magnetic *** vibration (NMR) images, and ultrasound images. In the medical treatment, according to the relevant data formation, and then realize the presentation of geometric patterns, such as 3D, restore the body of the various tissues, for the small parts of the zoom observation can be realized, can realize the quantitative understanding of the doctor, more detailed observation of the lesions, for the next medical treatment to provide help. For example, in the nuclear magnetic *** vibration imaging therapy, the first set a certain magnetic field, through the radio frequency pulse excitation 'way, the body in the hydrogen nucleus for stimulation, in the process of generating *** vibration, to promote the body's ability to absorb, to help find the location of the disease [2].
2.2 Enhance the efficacy of radiation therapy
In medical treatment, the use of digital image processing technology can realize the observation of the diseased area, but also to achieve the treatment of the diseased area, which is commonly used in the radioactive treatment of tumors or cancerous lesions. Before the treatment, the first position is located in the direction of the patient, after accurate positioning, with the help of digital image processing technology, a full range of plans for the treatment program, and on this basis for the treatment of the patient. For example, in the treatment of tumors and cancers and other lesions, the use of digital images to check the condition of the body outside the lesion, reducing the risk of surgery.
2.3 Deepening the understanding of brain tissue and its functions
Brain tissue is the core of human functioning, and there are many complex structures in brain tissue, so to realize the functional understanding of brain tissue, it is necessary to carry out all-around observation of brain tissue, and y analyze the structure of its various tissues. In recent years, with the improvement of medical technology, digital image processing technology has been used in medicine, and digital image processing technology can realize all-round observation of brain tissue through the cerebral cortex, and finally present the operation of various institutions in the brain in a three-dimensional manner [3]. For example, functional magnetic **** vibration imaging that is FMRI, this imaging can be detected on the body of the cerebral cortex activity, but also real-time tracking of signal changes, its high-definition temporal resolution, for the contemporary medical care to provide a lot of help.
2.4 Realization of the digital anatomy function
Digital anatomy is virtual anatomy, this kind of anatomical behavior needs to be based on high-tech from the mechanics, vision and other aspects, through the virtual human resources to establish, dialysis of the body's various tissues and structures, the realization of the anatomy of the virtual human, to increase the body's understanding of the real restoration of the knowledge related to anatomy, this means of teaching for the medical treatment and anatomical research has an important impact on the role of the anatomy. This is an important tool for medical teaching and anatomical research.
3 Conclusion
In summary, digital image processing technology has an important application value in medical imaging, the development of its technology provides a platform for the progress of medical technology, but also for the development of digital image processing technology to provide the application of space, the combination of this is the requirements of the development of the community, and the trend of the times.
This is the first time that we have seen this.
