Abstract

This invention relates to a system and methods for determining the initiation and/or the termination of an autonomous in vivo imaging procedure, such as by a capsule imaging the gastro intestinal tract.

Claims

1. A method of determining termination of an in vivo capturing procedure by an autonomous device comprising the steps of:

determining whether a condition with respect to said device has been met;

if said condition has been met, setting the device to a beacon mode;

receiving a signal from the device;

determining if said signal is a beacon signal, an imaging signal or neither;

if the signal is a beacon signal, determining that the in vivo image capturing procedure is terminated;

determining, based on analysis of images captured by the autonomous device, whether the autonomous device is in vivo; and

providing a notification of whether or not the autonomous device is in vivo.

2. The method of claim 1, further comprising, if the in vivo image capturing procedure is terminated, providing a notification.

3. The method of claim 1, further comprising detecting the signal type based on said signal'"'"'s power intensity, frequency, rate, length or content.

4. The method of claim 1, further comprising the step:

if no signal is received from the device, determining termination of the image capturing procedure.

5. The method of claim 1, further comprising using an RF scanner to determine if the device is still in the patient'"'"'s body.

6. The method of claim 1, further comprising based on said signal type, determining if the in vivo image capturing procedure is initiated.

7. The method of claim 1, wherein the condition is a low battery voltage;

a completed, stopped or terminated image capturing procedure;

a lapse of a predetermined period of time;

or the capsule having reached a predetermined position in vivo.

8. The method of claim 1, wherein the step of determining that the in vivo image capturing procedure is terminated is done only if a predetermined period has elapsed.

9. A system for determining termination of an in vivo image capturing procedure comprising:

an autonomous imaging device for imaging a body lumen, the device comprising a sensor for sensing a condition in vivo and a transceiver to transmit signals wirelessly, the transceiver being operable at least in an image capturing mode or in a beacon mode;

a control unit to switch between the image capturing mode and the beacon mode based on the condition sensed;

a receiving unit to detect a signal transmitted from the imaging device and to determine if the detected signal is an image signal, a beacon signal or neither;

a processing unit to determine whether an image capturing procedure has terminated, based on analysis of the detected signal, the processing unit further to determine if the autonomous imaging device is in vivo by analyzing images received from the autonomous imaging device and to provide a notification of whether or not the autonomous imaging device is in vivo.

10. The system of claim 9 wherein the receiving unit detects the received signal power intensity, frequency, rate, length or content.

11. The system of claim 9 further comprising a notification unit to notify a user if image capturing procedure has or has not terminated.

12. The system of claim 9 wherein the processing unit to determine if the autonomous imaging device is in vivo is provided in the receiving unit.

13. The system of claim 9 wherein the analyzed images are the last image or plurality of images that were received from the imaging device.

14. The system of claim 9 wherein the autonomous imaging device further comprises an RF identification unit.

15. The system of claim 9, wherein the condition is a low battery voltage;

a completed, stopped or terminated image capturing procedure;

a lapse of a predetermined period of time;

or the capsule having reached a predetermined position in vivo.
