Real time detection of gastrointestinal sections and transitions of an in-vivo device therebetween
First Claim
1. A method for detecting the movement of an in-vivo device between sections of a gastrointestinal (GI) tract, comprising:
- for a stream of image frames, each of the frames comprising an image captured in vivo by an in in-vivo device traversing the GI tract and related non-image data;
sequentially classifying frames from the stream of frames, as being associated with a GI region based on the image data, the classifying producing frame classes;
analyzing the frame classes; and
determining whether the in-vivo device is in a particular GI section based on the analysis.

Abstract
An in-vivo device captures images of the GI system and transfers frames to an external system for analysis. As frames are transferred from the in-vivo device to the external system frames may be classified as belonging to a particular GI section. Based on statistical analysis of the classes, a temporary determination may be made, that the in-vivo device has transitioned to a “target section”, and, as a result of the temporary determination, the operation mode of the in-vivo device may temporarily change from a first mode to a second mode. If the temporary determination is followed by a determination which is based on analysis of additional classes, the determination that the in-vivo device is in the target section may be made final and the in-vivo device may remain in the second mode. Otherwise, the first operation mode may be resumed and the whole transition determination process may start anew.

4. A method for detecting transition of an in-vivo device between sections of the gastrointestinal (GI) system, comprising:
-
a) receiving a stream of frames, each of the frames comprising image data corresponding to an image captured in vivo by an in in-vivo device traversing the GI tract and related non-image data; b) classifying frames from the stream of frames, one frame at a time, as related to a particular GI section or as not related to any particular GI section based on image data, wherein each frame to be classified is classified by the time the next frame to be classified is received, the classifying producing frame classes; c) analyzing the frame classes statistically; and d) determining whether the in-vivo device is in a particular GI section or has transitioned to a particular GI section based on the analysis. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. An in vivo imaging system for detecting transition of an in-vivo device to a target GI section, comprising:
-
a memory to store a stream of frames, each of the frames comprising image data corresponding to an image captured in vivo by an in in-vivo device traversing the GI tract and related non-image data; and a processor to; classify frames from the stream of frames, one frame at a time, as related to a particular GI section or as not related to any particular GI section based on image data, wherein each frame to be classified is classified by the time the next frame to be classified is received, the classifying producing frame classes; analyze the frame classes statistically; and determine whether the in-vivo device is in a particular GI section or has transitioned to a particular GI section based on the analysis. - View Dependent Claims (17, 18, 19, 20)
