The Functions of Image Diagnosis
Medical image diagnosis occupies a considerable proportion in modern medical activities. With the continuous development of visualization technology, modern medicine has become increasingly inseparable from medical image information, and is playing an extremely important role in clinical diagnosis and medical research. Medical image information is diversified, such as B-scan images, color Doppler ultrasound images, magnetic resonance (MRI) images, X-CT images, X-ray images, various electronic endoscopic images, and pathological slices under a microscope Images etc. With the in-depth development of medical diagnostic visualization technology, people are constantly striving to seek clearer and more diagnostically valuable high-quality medical images. In the past decade or so, Chinese hospitals have introduced a large number of imported advanced medical imaging equipment, which has played an important and active role in improving the level of diagnosis and strengthening the management of hospitals. Due to financial difficulties and the level of instrument design, most medical imaging equipment does not consider the image storage and transmission functions, at best, it is equipped with a printer or X-ray film for image recording. The doctor's diagnosis is based on the naked eye observation of the image on the screen of the instrument, and the analysis and diagnosis based on personal experience. There are many subjective components.
With the rapid development of electronic computer technology, especially multimedia technology, the storage and transmission of medical images have become possible. The application of large-capacity hard disks, image information compression technology, and read-write optical discs has enabled the storage of medical images in large quantities. The formulation of the DICOM3.0 standard enables a unified standard for the transmission of medical images and various digital information between computers. Through the data interface and the Internet, the remote transmission of medical image information can be carried out, and remote consultations can be realized. PACS is an important condition for realizing medical image information management. It digitally processes medical images from acquisition, display, storage, exchange and output, and finally realizes image storage and transmission.
In addition, through the intelligent computer processing of medical images and information, image diagnosis can abandon traditional visual observation and subjective judgment. With the help of computer technology, the pixels of the image can be analyzed, calculated, and processed to obtain relevant complete data and provide more objective information for medical diagnosis. The latest computer technology can provide not only morphological images, but also functional images, so that Medical image diagnosis technology is going to a deeper level. For example, Siemens' syngo.via system has changed the traditional image post-processing concept, completely abandoned the software-oriented traditional CT workstation working method, opened up a new working perspective oriented to anatomy or disease diagnosis, and became the first direct service for disease diagnosis. Image work platform. It frees the diagnostician from the tedious post-processing of images and focuses on medical diagnosis. syngo.via also won the 2010 IF Product Design Award for its user-friendly operation interface.
