Abstract

With the rapid development of information technology and computer technology, hospital information, and medical digital construction tide has come. Telemedicine to become one of the the most extensive areas of this tide of development prospects. In this paper, the operating principle of high energy intensity focused ultrasound tumor therapy equipment products and its supporting equipment as telemedicine service object, treatment of the theory, methods of operation, and data characteristics analysis, the researchers found that the use of computer visualization to control ultrasonic energy to kill tumor lesions not only the need for accurate and efficient image processing, strict dose treatment orientation, release energy need simple and flexible development module and a reasonable computing resources layout. PACS applications become increasingly widespread, but for special medical image format data in the display, transmission and other aspects, the current lack of a modular application control and compression parameters standard makes developers need to invest a lot of manpower and material resources to carry out this work. It can be said, lack of medical image file browser module and a single image processing development environment into restricting the construction of hospital information (HIS), image archiving and communication system (PACS) and the project (TMS telemedicine terminal, HIFU the doctors exchange platform, HIFU consultation The platform) functional development bottleneck compression standard is not clear, but also makes a number of projects in transmission efficiency and doctors on the balance between the image satisfaction wavering. Imaging applications for HIS, PACS development bottleneck problem of using digital image \Browse DICOM image-based files, format conversion and compression of the common module. Collected through clinical cancer therapy MRI, CT and other types of images for the naked eye doctor requirements identified nine kinds of image data compression reference table and NET framework under the the System.Runtime.InteropServices interface with common the module output Hbitmap dovetail compression processing of the obtained image stream using GDI technology. DICOM image browser generic module to achieve using COM technology VC 6.0. NET technology mixed development of a new model, applied to the remote diagnosis system. Another important factor as the recording and monitoring of the operation of medical equipment, remote medical diagnosis. Exchanges (such as B ultra developing and positioning, surgical planning, the energy intensity of the lesions on postural sites change over time, the curve, the determination of the safety threshold, HIFU dose) for the treatment effect and experience, as well as the patient responsible stressed treatment standardization, and strict inspection tools and detailed recording equipment operating status, operation log, the need for a large medical device data for effective management, and allow these data to be able to exchange value. However, due to the special nature of the medical industry products and targeted, difficult for all medical devices have the same communication capabilities. Running a huge amount of data, for the stability and safety of the treatment, the various devices as much as possible so that the single function of the present apparatus. For consideration of the independence of medical privacy and the construction of hospital information, some large equipment and Internet. To solve these problems, this paper proposes the eventual establishment of a multi-process device-based of equipment data separate management and multi-process data import, processing time efficiency model, a better solution to the universal problem of data entry with different equipment. Finally, an overview of the included in the telemedicine project similar to NetMeeting, but more in line with the characteristics of medical consultation teleconsultation system, the system contains audio dialogue, video exchange of HIFU device data management, image transmission with online outline function. And creative use of AJAX technology and XML technology. NET technology for the introduction of WebGIS principle WebService-based medical image browsing and online design the synchronization sketched platform (B / S Sketchpad). Compared with NetMeeting, the system reduces the network traffic and to facilitate communication among physicians. Research-based of equipment data separate management and multi-process equipment data import mode C / S, B / S mixed application mode, solve the problem of information security and equipment data acquisition versatility. Logging but also for the operation of large-scale medical equipment and treatment plan based on HIS safety record provides a method and laid the foundation for the future establishment of a database of experts. Windowed display technology to resolve the problems of ordinary PC display of medical images (including DICOM), modular platform WebService/J2EE use of new B / S mode. Introduces the WebGIS principle, to establish different from NetMeeting and C / S Sketchpad consultation pseudo-dynamic mode, combining XML the AJAX technology design WebService-based medical image browsing and online synchronization sketched platform (B / S Sketchpad) for remote diagnosis and treatment the new mode. Ultimately, the design the HIFU telemedicine overall planning of the project and goals, and to achieve. The Clinical Experimental results show: equipment data into the database, the accuracy, completeness, rapid and operation of equipment in the network environment are inseparable. If you do not have a good network environment, not even isolated network environment equipment, HIFU device data management system can still allow doctors to manually select the need to store or published and remote diagnostics data files in a network environment under transfer entered into the database via a web and to ensure the safety and accuracy of the data. B / S structure of medical imaging module and line drawing board function is applied to the remote diagnosis system, greatly facilitates the Doctor offsite exchange, updated the traditional mode of telemedicine in the past, has achieved the desired results. Through COM technology, the use of the respective advantages of the VC. NET, mixed development to achieve the above research. Greatly improve the development efficiency. In addition to audio and video portion of the drawing board and C / S as of predecessors on the basis of other than the rectification work, design ideas and features mentioned in this article are of independently.
