    • A system and method for measuring and analyzing motility within a body lumen such as the gastrointestinal (GI) tract, where an in vivo imaging device such as a capsule captures images and transmits the images to a processor, which calculates the motility of the device based on comparison of the images. Preferably, the processor compares the intensity of pairs of images or of elements of pairs of images, generates a variance for the compared images, and calculates the motility of the imaging device from the variances. The motility data may be presented to a user in various manners; for example, a plot of motility over time may be generated, or indications of low motility may be presented to the user of the system.
    • 一种用于测量和分析诸如胃肠(GI)管道的体腔内的运动性的系统和方法,其中诸如胶囊的体内成像装置捕获图像并将图像发送到处理器,该处理器计算基于装置的运动性 比较图像。 优选地,处理器比较图像对或图像对的元素的强度,为比较的图像生成方差,并根据方差计算成像装置的运动性。 运动数据可以以各种方式呈现给用户; 例如,可以产生随时间的运动性图,或者可以向系统的用户呈现低运动性的指示。
