基于超声定位的胃动力检测系统的设计

Gastric Motility Detection System Design Based On Ultrasound Localization

目的:由于胃的形状、大小、位置、方向存在个体差异,及胃在蠕动、排空过程中容积的变化较大对胃动力信息检测造成了比较上的困难。因此本系统的设计引入超声作辅助定位。方法:设计全数字超声定位模块,通过USB接口把采集的数据传输到PC机,并开发相应的超声图像采集程序。结果:系统设计通过调试,成功的采集到胃的超声横断面图,获得的胃部结构图能够满足本系统辅助定位要求。结论:超声辅助定位的引入,可以有效解决胃动力信息的横向比较困难问题。

Objective： As the shape, size, location, direction of stomach existence individual diversity, and the cubage of the stomach existence large change during the process of squirming and emptying, which cause difficult to comparative gastric motility signal. Therefore, the system design introduces the ultrasound-assisted localization. Methods： Design an all-digital ultrasound localization module, then transfer collect data to PC through the USB interface, and develop the ultrasound image acquisition program. Result： The system is designed successfully, it can acquire the ultrasound cross-sectional map of stomach, which meets the requirements of auxiliary orientation. Conclusion： The ultrasound-assisted localization introduced, which can effectively resolve the problem what the gastric motility signal is difficult to horizontal compare.
