US20060183993A1 - Device, System, and Method for Locating An In-vivo Signal Source - Google Patents > 자유게시판

More particularly, the present invention pertains to gadgets, methods, and methods for locating an in-vivo sign supply. Devices, systems and methods for in-vivo sensing of passages or cavities inside a physique, and for sensing and gathering data are known within the artwork. In-vivo sensing devices such as capsules might embrace a sensing system and a transmission system, wherein the sensing system collects information and the transmission system transmits the collected data utilizing Radio Frequency (RF) to an external receiver system, e.g., for additional processing and show. Some in-vivo imaging systems include a picture sensor carried inside a swallowable gadget comparable to a capsule. GI tract, or different body lumen or body cavity being imaged, iTagPro product while the gadget might pass by means of your entire digestive tract and should operate as an autonomous video endoscope. Prior attempts have been made at monitoring an intra-gastric and intrauterine transmitting gadget embody spatially scanning a non-ambulatory affected person with a receiver. Such programs might require laboratory gadget that is probably not portable and will not be industrial.

Some embodiments of the invention present, for instance, a system and ItagPro technique for tracking an in-vivo picture sensor, the system together with a location detecting unit to find the in-vivo image sensor over time and an information modifying unit to modify the information sampled by the situation detecting based on, for instance, data sensed by the in-vivo picture sensor. Other suitable strategies could also be used to switch and/or enhance information sampled form the location detection unit as may be described herein. Embodiments of the invention might enable various other benefits, and could also be used in conjunction with various different applications.
