    • Provided are a system and method for supporting a logical sensor network (LSN) separate from an actual physical sensor network (PSN) to readily obtain sensing data required by a user or application program in an environment consisting of various types of PSNs. The system includes a metadata database (DB) for storing metadata of a plurality of available PSNs each having a plurality of sensor nodes, a LSN generation module for generating a LSN including one or more PSNs among the PSNs registered in the metadata DB or one or more sensor nodes in the PSNs, and storing metadata of the generated LSN in the metadata DB, a LSN update module for updating the metadata of the LSN including the PSNs or the sensor nodes in the PSNs when a state of the PSNs or the sensor nodes is changed, and a query processing module for, when a query about the LSN is received from an application program, collecting sensing data from the PSNs or the sensor nodes included in the LSN, generating query result data for the LSN using the collected data, and providing the query result data to the application program.

    • The present invention provides an integrated PET/CT system that can simultaneously or sequentially take PET pictures and CT pictures, in which an integrated PET detector module is formed by packaging a plurality of PET (Positron Emission Tomography) detectors in a can or a cartridge, an integrated PET/CT detector module is formed by mounting a front end of a flat-panel x-ray detector at the PET detector, and the PET/CT detecting modules are mounted to a gantry.The integral PET/CT detecting module that is the most important component of the present invention can take CT pictures by mounting a flat-panel x-ray detector (or DR (Digital Radiograph)-detector) at the front end of a common PET detector, and the flat-panel x-ray detector can minimize attenuation and scatter of gamma rays, such that it is possible to minimize interference due to the x-ray detector in acquiring a PET picture.Since the integrated PET/CT system proposed of the present invention uses one integrated gantry, unlike the PET/CT products formed by simply combining PET and CT systems in the related art, it is possible to remarkably reduce the volume of the system by integrating additional periphery devices and driving devices, reduce the manufacturing cost of the system, provide improved PET/CT composite pictures, and simultaneously acquire PET and CT pictures. Further, it is possible to remove the limit in space for installing the system by achieving a slim system, and attenuate anxiety of patients by reducing the length of a tunnel through which the patients pass in taking pictures of the patients.
    • 本发明提供一种能够同时或顺序地取得PET图像和CT图像的集成PET / CT系统,其中通过将多个PET(正电子发射断层扫描)检测器封装在罐或盒中而形成集成的PET检测器模块, 通过在PET检测器上安装平板X射线检测器的前端来形成集成的PET / CT检测器模块,并且将PET / CT检测模块安装到台架。 作为本发明最重要的组成部分的整体PET / CT检测模块可以通过在普通PET检测器的前端安装平板X射线检测器(或DR(数字射线照片)检测器)来获取CT图像 ,并且平板X射线检测器可以使γ射线的衰减和散射最小化,使得可以在获取PET图像时使由X射线检测器引起的干扰最小化。 由于本发明提出的综合PET / CT系统使用一体式门架,与现有技术中通过简单地组合PET和CT系统形成的PET / CT产品不同,可以通过集成额外的方式显着地减小系统的体积 周边设备和驱动设备,降低系统的制造成本,提供改进的PET / CT复合图像,并同时采集PET和CT图像。 此外,可以通过实现苗条系统来消除用于安装系统的空间限制,并且通过减少患者在拍摄患者时通过的隧道的长度来减轻患者的焦虑。
