System and method for checking the status of an in-vivo imaging device
A system and method for monitoring the status of a battery in an in-vivo imaging device, prior to use of the in-vivo imaging device. The device may include a frame counter for counting the number of frames captured and may include monitoring the voltage of the battery. A warning signal is generated if it is determined that the battery is faulty prior to use. The warning signal can be generated by the device and/or by a receiver which receives data from the in-vivo imaging device and/or a by workstation which receives the data from the receiver.
1. A method for checking the status of a swallowable in-vivo imaging device powered by a battery, comprising the steps of:
counting image frames captured by an imager located in the in-vivo device;
registering said captured image frames by a processor; and
indicating a warning if a number of image frames counted by the frame counter prior to swallowing of the in-vivo imaging device exceeds a critical number of frames,
wherein the critical number of frames is calculated based on a lifetime of the battery, the amount of time required for sensing passages or cavities within a body of a patient, and an image frame capture rate of the imager,
such that a difference between a lifetime of the battery and a division of the critical number of frames by a frame capture rate is greater than a time necessary to complete imaging of a required length of the gastrointestinal tract.
2. The method according to claim 1 , wherein the in-vivo imaging device is a swallowable capsule.
3. The method according to claim 2 , wherein the swallowable capsule is autonomous.
4. The method according to claim 1 , wherein the warning is indicated by an indicator located in the in-vivo sensing device.
5. The method according to claim 1 , wherein the warning is indicated by the in-vivo imaging device shutting down.
6. The method according to claim 1 , wherein the warning is indicated by the in-vivo imaging device suppressing the operation of illumination sources.
