Gastrointestinal Transit Measurement System

描述(由申请者提供)：胃肠动力障碍是一个严重的健康问题，每年有数百万人去看医生。在许多患者中，胃肠传输的测量可以提供重要的诊断信息。然而，目前的凌日测量技术涉及辐射，无法进行全面评估患者所需的长时间、高度详细的记录。 这个项目的目标是开发一种新的技术来测量运动障碍患者的胃肠传输。这项技术捕捉到了胃肠道传输的细节，不涉及辐射，并且能够在患者进行日常生活的同时进行长时间的记录。 在该项目的第一阶段，建造了胃肠运输测量系统(GTMS)的原型，并在实验室中成功地进行了测试。在第二阶段，该系统将得到增强，以支持完全活动的受试者的手术，并使用胃肠功能正常的志愿者受试者进行评估。

DESCRIPTION (provided by applicant): Gastrointestinal motility disorders are a significant health problem accounting for millions of physician visits each year. In many patients, measurement of gastrointestinal transit can provide important diagnostic information. However, current transit measurement techniques involve radiation and cannot make the long-duration, highly-detailed recordings needed to fully evaluate patients. The goal of this project is development of a new technique for measurement of gastrointestinal transit in patients with motility disorders. The technique captures the fine details of gastrointestinal transit, does not involve radiation, and is capable of making recordings for extended periods while patients undergo their daily routines. In Phase I of this project, a prototype of the Gastrointestinal Transit Measurement System (GTMS) was constructed and successfully tested in the laboratory. In Phase II, the system will be enhanced to support operation on fully ambulatory subjects and evaluated using volunteer subjects with normal gastrointestinal function.
