The Teaching and Learning of Medical Imaging Physics in Higher Education Imaging Programs Abstract: According to the characteristics of the course, the current situation of the students, we attach importance to the quality of teacher training, clarify the level of the teaching materials and the relationship with the students, the use of a rich variety of teaching methods, change the abstract exposition for the theory of the link to the practical teaching, improve the medical imaging technology, and improve the teaching of medical imaging technology. Visualization teaching, improve the teaching quality of medical imaging physics course. Keywords: senior medical imaging physics teaching discussion In recent years, the rapid development of large-scale medical imaging equipment, greatly improving the level of diagnosis and treatment. With the more urgent need for medical imaging professionals, many undergraduate medical schools in China have set up a medical imaging program. And with the development of community health care in China, the number of students who apply for medical imaging majors in colleges of higher vocational and technical colleges continues to increase. In Hubei Vocational and Technical College, for example, the number of students admitted to the imaging program has increased from one class to two to three classes per year. Regardless of whether the institutions focus on cultivating highly educated medical imaging clinical diagnosis professionals or highly educated medical imaging engineering and technology talents, they have emphasized the importance and necessity of opening the basic medical imaging physics (hereinafter referred to as imaging physics) course during the process of setting up the professional curriculum. Some undergraduate colleges and universities in clinical medicine began to open imaging physics as an elective course, the purpose is to allow clinicians to have the basic theoretical knowledge of medical imaging, for the future of the subsequent professional courses - medical diagnostic imaging or medical imaging to provide the necessary theoretical basis. 1. The current situation of the curriculum of imaging in higher vocational medical schools Taking Hubei Institute of Vocational Technology as an example, the imaging program in higher vocational medical schools now enrolls high school liberal arts and sciences students as well as intermediate vocational students. In terms of course offerings, only in the first year of college to open the foundation of medical electronics this science and technology courses, related to the lack of knowledge of higher mathematics, the students' mathematical and scientific foundation is relatively weak. Fundamentals of medical imaging physics is a cross-discipline, and a very important professional foundation course. The purpose of teaching is to enable students to master the basic principles of physics of medical imaging theory, law; to understand the physical theory of medical imaging; to lay the foundation for a deep understanding of the imaging process, evaluation of the image, as well as reading and recognizing the image, digging the image of the biological information contained in the image. This requires a certain amount of advanced mathematics, nuclear physics, quantum physics, ultrasonic physics, and many other knowledge to make a pad. Of course more basic knowledge related to imaging technology is needed. In the face of all this necessary knowledge, it is a fact that senior imaging majors can not be completed in a limited time and a limited number of credit hours. In fact, imaging physics is a new course born along with the establishment of the imaging profession, which has existed in China for less than ten years. Therefore, from teaching materials to teaching, all schools are in the stage of feeling their way forward. How to make higher vocational students in the premise of no foundation to effectively learn the course, I will be in a few years in the teaching process of their own teaching experience to write, with you **** with the discussion. 2. Improve the professional quality of teachers, must establish professional thinking Due to the lack of relevant faculty, the current teaching tasks of imaging physics in various institutions are mostly undertaken by teachers in the physics teaching and research department. However, the professional nature of the two courses of physics and imaging physics is very different, the former is a basic science course, the latter is a professional basic course. Teachers engaged in the teaching of imaging physics must have a certain degree of medical professional knowledge, with a high degree of professional quality, teaching must set up a professional idea, in order to combine the knowledge of physics and imaging knowledge organically, to enhance the students' interest in learning, and to improve the teaching quality of the course. Therefore, the teaching staff should strengthen their own professional quality, use the opportunity of clinical training to learn imaging knowledge and practical technology, and try to do a good job of teaching. 3. The depth of knowledge must be appropriately grasped during the teaching process The physics of imaging is established by the teaching staff in the teaching process of the prior opening of the imaging professional colleges and universities. It is the knowledge of higher mathematics, physics, imaging theory, computer technology and other knowledge applied to ultrasound imaging technology, X-CT imaging technology, isotope imaging technology, magnetic *** vibration imaging technology in a cross-disciplinary. Knowledge of the starting point is very high, students learn to have a certain degree of difficulty, in the teaching process should be appropriate to grasp the depth of knowledge of the material, the explanation needs to be in-depth, easy to understand. For example, the description of the ultrasonic field part, involving more advanced mathematical knowledge, in the teaching process should pay attention to guide students to focus on understanding the nature of the distribution of the field, the description of the physical significance of the amount of the field, and so on, and try to avoid the students due to the mathematical knowledge is less than to reduce the understanding of the course and interest in learning. Magnetic **** vibration part, students need to have a certain atomic nuclear physics, quantum mechanics knowledge in order to accurately understand the nuclear spin energy levels, jumps and other concepts and phenomena. In the teaching should pay attention to collect some information, try to use the more popular, classical, macroscopic hypothesis to explain, enhance the students' perceptual understanding of the microscopic world. 4. Pay attention to grasp the principles of imaging physics and imaging technology, imaging equipment related knowledge of the weight relationship X-CT imaging, ultrasound imaging, isotope imaging, magnetic **** vibration imaging in each part of the two main content: the basic principles of physics and imaging fundamentals. In the teaching process should be the main focus on explaining the basic principles of physics, there is no doubt that this is also a physics graduate teacher is the easiest to do, but the students' interest in learning is often focused on the imaging principles of the imaging technology involved, imaging equipment, and other knowledge to show more keen interest. Although imaging technology and imaging equipment will be explained in detail in the practical teaching of later specialized courses, here we make a brief introduction to this part to receive good teaching results. Over the years, our successive students have shown great interest in learning imaging physics. This has something to do with our teaching methods. 5. Pay attention to improve students' perceptual understanding of knowledge All parts of the knowledge of imaging physics are relatively abstract, and students generally find it difficult to understand and learn. Therefore, through a variety of means to improve students' perceptual understanding of knowledge, can play a multiplier effect on student learning to help. In the teaching process, we will gyroscope into the experiment to students to do a demonstration, explain the atomic nucleus in the nuclear spin and spin magnetic moment of the relevant knowledge; with the help of the propagation of sound waves and the reflection of knowledge of ultrasound measurement experiments to explain in detail; allocate a certain number of hours to lead the students to the affiliated hospitals related to the Department of study tours. Invite ultrasound, CT clinical diagnostic teachers and technical teachers to give students on the spot to explain the principle of the instrument, the operation method, and diagnosis, so that students have a perceptual awareness of the knowledge learned in the classroom to deepen their understanding, and received a very good effect. 6. To realize the multi-level, three-dimensional teaching materials As the course is applied knowledge, learning more difficult, we carried out a multi-level, three-dimensional attempts at teaching materials. The curriculum is the basis of the textbook, the textbook is the carrier of the curriculum, the textbook should be integrated into modern teaching techniques, to achieve diversification, matching and coordination. Our approach is: textbooks and modern multimedia tools are closely integrated. The teaching material system includes: (1) the traditional paper textbook "Medical Imaging Physics" (People's Health Publishing House); (2) the original electronic lesson plans for teachers' lectures, which are accompanied by a large number of homemade and clinical pictures and animations developed by themselves, and put forward the questions for students to think about; (3) learning software to assist students in self-study and research, such as the "Principles of CT and Magnetic **** vibration imaging CAI courseware (People's Health Electronic Audio and Video Publishing House publicly published and distributed, was included in the ? Eleventh Five-Year? National Key Electronic Publications); (4) 2 web page form courseware. Initially formed a multi-form, multi-purpose, multi-level teaching resources and a variety of teaching services for the purpose of structural supporting the collection of teaching publications. In short, imaging physics is a new course, only to continue to explore, constantly summarize the experience, and gradually improve the teaching methods and means to enhance the teaching effect. Through the efforts of several years, on the one hand, students see that what they learn now is what they will use in the future, and improve the interest in learning basic courses, on the other hand, students have developed the ability to learn, and at the same time, the follow-up courses?

"Ruminations on image fusion to promote the development of the field of medical imaging 》 Abstract: The progress of science and technology not only drives the development of industry and commerce, but also promotes the development of medical development, computer technology is widely used in imaging Medicine. Now a variety of medical examination instruments are more and more sophisticated, more perfect function, the storage and transmission of image information for medical research and diagnosis to provide a better basis. The fusion of medical images is the fusion of image information, which is assisted by computer technology to diagnose the condition. The fusion of medical imaging is a new direction of development of medical imaging, this paper analyzes the fusion of medical imaging and discusses the impact and role of image fusion on the development of medical imaging. Keywords: medical imaging, image fusion, diagnosis I. Image fusion Medical image fusion is actually the use of computer technology, the fusion of image information. This includes digital processing of image information, and then data synergy and matching, to get a new image information to get a better observation of the condition, with the computer as an auxiliary means, so that the diagnosis is more accurate, figurative. The development trend of image fusion The trend of image fusion Medical imaging is one of the fastest growing clinical disciplines in recent years, in which ultrasound, radiology, etc. have long been applied to the diagnosis of medicine, but in the face of a variety of symptoms in different patients, a single imaging examination is no longer sufficient as a basis for diagnosis. Therefore, image fusion is becoming more and more a focus in medicine, people prefer to use multiple image examination, comparison and analysis, so that the examination results are more accurate and better assist the treatment of clinical diseases. The development of impact fusion improves the comprehensive level of medical diagnosis and is of great significance in promoting the development of imaging. Moreover, the fusion of medical imaging can not only add to the diagnosis, but also provide help for treatment. For example, X-ray, ultrasound, focusing and magnetic **** vibration combined together for treatment. The development of impact fusion is imperative and will drive the renewal and development of medical imaging. The need for image fusion 1. The updating and development of medical technology requires impact fusion Computer technology is widely used in a variety of fields, and this includes medical imaging. With the development and implementation of new technologies, image post-processing technology also needs to be constantly improved, and the fusion technology of images is the new development of post-processing technology. The synchronization of front and back technology can better bring out the benefits of imaging. 2, image fusion to make the examination more comprehensive and accurate Imaging means of examination is a lot, from ultrasound to radiation to CT, etc., each examination is targeted, but because of this there are certain limitations. Each test has a single limitation, which can only accurately reflect one aspect of the data value, which is not conducive to the diagnosis of the disease. The fusion of images makes up for this shortcoming. 3. Clinical diagnosis requires image fusion All means of examination are for the ultimate clinical treatment, and diagnostic imaging is the same for clinical treatment. The fusion of the impact of a number of advantages of a single examination, presenting a clearer image, more convenient for the doctor's judgment, so that the diagnosis is clearer and more accurate, but also according to the diagnosis to provide a better treatment plan, to assist in the clinical treatment. Influence the integration of methods and technology application First is the integration of information technology. No matter what kind of diagnostic technology, the last thing to get is the information that this technology can diagnose. The fusion of the image first to implement the fusion of information, image data conversion is the key to understanding. The image conversion will be different inspection equipment to detect the image information for the format of the conversion and adjustment, so that it is more realistic presentation of the state of the test site to ensure the accuracy of the diagnosis. Second is the integration of digital technology. The establishment of an image database is more intuitive and easy to extract information. There is also the application of computer technology, the fusion of these technologies, so that the image fusion examination is more specific and detailed. Methods of image fusion: boundary mark pairing, surface phase law, spatial moment pairing, cross-correlation method. Fourth, the clinical value of medical image fusion Modern medicine has been computer technology to obtain the image information processing research results applied to the diagnosis of clinical medicine, the results of the examination through the computer technology to analyze, processing, image fusion to reproduce a high definition, high quality images. The main clinical values are as follows: Help in clinical diagnosis The image fusion will clearly present the structure of the examination site and the surrounding tissues, and through the image diagnosis, the doctor will be able to understand more about whether the tissue morphology of the test site is diseased or not as well as the extent of the lesions. In many diseases, early lesions are not obvious, and if they are not detected, the best time for treatment may be missed. The fused images can be zoomed in to mark out the differences in the tissues, making it easier to observe and diagnose, detecting lesions in a timely manner, and reducing the number of missed diagnoses. Helps with surgical treatment Image fusion combines image reconstruction and 3D stereotactic technology, which can clearly show the condition and spatial status of the lesion and its surrounding tissues, allowing the surgeon to formulate a surgical plan based on the fused images and provide real-time displays during the surgical procedure, and providing a convenient way of post-surgical observation. For medical research The fusion of images combines the advantages of multiple tests to provide more comprehensive and clearer image information, and more obvious pathological features, which is a very valuable imaging data for medical research, and provides a better basis for future research on diseases. Conclusion: The fusion of medical imaging is the integration of the advantages of a number of examinations, through a series of computer technology to integrate and process the re-formation of new images. The fusion of medical imaging is a great update of the development of medical imaging technology, which will be a variety of various technologies are integrated into the medical examination and diagnosis, promoting the further development of imaging.
