PC environment, nuclear medicine imaging system

Layers are used to construct a PC-based nuclear medicine imaging environment, and diagnostic layer can be said to be based on the environment, nuclear medical imaging post-processing, then analysis methods, including image fusion complex, three-dimensional reconstruction, quantitative analysis medical diagnostic studies and computer image processing algorithm. Diagnostic layer system functions framework extended repeatedly 1. Medical image archiving PACS (picturearchlevingandcommuni-cationsystem image archiving and communication system) + is an important current information science in the development of medical image processing is a hot research field. We developed image processing system in nuclear medicine patient records and image databases and image processing blocks will provide a complete medical image archiving system, as a computer automatic management, diagnostic filmless basis. 2. Image processing and auxiliary diagnostic features of the environment on the basis of image processing to provide supplementary diagnostics. Including; anatomy, physiology, pathology of some basic knowledge of the Navy General Hospital, 1998 Volume 11 No. 2 187 knowledge, and nuclear medicine system development status of a typical case. Medical records and medical image database management module and image database management module of the algorithm are a variety of database input, modify, query, processing, maintenance and output method; the module development ideology: the basis of the data structure. Processing function module} to the data dictionary as the core. Design a database; from the data stream to the logical flow of generic modules and specific modules design. According to the size of the system's data and investment, nuclear medical imaging management system using relational database management system as a development platform, as xBAsE series of database operations and relations between the integrity of the support is not sufficient, without supporting data dictionary management, to consider to the system should have the flexibility, scalability and maintainability, we have developed a data dictionary-based information management system. Programming is very easy to control and system expansion. 2. Nuclear medicine imaging touch block (1) the application layer to improve the image quality for a variety of needs,[link widoczny dla zalogowanych], providing a variety of image processing means. Noise filtering include: spatial, temporal mean filtering, median filtering, adaptive filtering, morphological filtering algorithm; edge detection, including: edge sharpening, edge enhancement,[link widoczny dla zalogowanych], contour tracking, I gray operations include: Images ash degree of transformation (linear, exponential, logarithmic). Image histogram, image inversion, etc.; geometric operations include: payment of interest Fourier transform image, image rotation, zoom, etc. I also re-sample images, pseudo-color to enhance the visual effect I basically cover all the classic image processing algorithms . All of these processing functions can handle the whole lot of images. Can also deal with a ROI (re-gionofinteresting region of interest). (2) diagnostic layer ① provides a powerful ROI management. Provides a square, circle, straight line, polygon, any shape ROI's drawing, moving, scaling, measurement and statistical analysis of data can be - ~ M ROI on the image to the file is saved, you can also read from a file display. This part of the function is performed by further diagnostic procedures and to achieve practical basis for diagnosis. ② nuclear medicine imaging for the needs of a developed a series of appropriate units in the clinical diagnosis of nuclear medicine applications. Including the body, heart, brain, liver,[link widoczny dla zalogowanych], spleen, kidney, lung, thyroid, bone scan and other categories. ③ According to the diagnostic needs, developed a series of image sets financial instruments, mainly various three-dimensional image position adjustment tool. Different resolution images and the necessary treatment. Currently developed a thyroid and heart diagnostic procedures. Conventional treatment of thyroid functional imaging into 5rain 2Omin static dynamic image processing and image processing. Simply enter the picture and the relevant parameters, the results can be illustrated report. The results generated report on the results of thyroid function imaging processing to save the file, open access to a doctor at any time. Heart and brain diagnostic procedures to achieve three-dimensional surface reconstruction and projection reconstruction, to facilitate direct observation of a doctor. Given the accuracy of SPECT, the system provides a relative quantitative analysis (including the two-dimensional, three-dimensional) tool, and the absolute quantitative analysis of SPECT try to do some of the system based on PC. Used in all Chinese language interface, take full advantage of the resources the Chinese WINDOWS,[link widoczny dla zalogowanych], Original software with the machines, compared with a friendly interface and simple operation. Taiwan more appropriate use of health care workers in China,[link widoczny dla zalogowanych], the system uses open architecture, according to the requirements of the user to expand and improve. The current system is still under development and improvement phase. On this occasion, fully describes the system's structure, function, in order to achieve the purpose of discussion with their peers.
