Abstract

An in-vivo sensing system including an in-vivo sensing device, a data recorder a receiver and a work station. The data recorder receives data signal from the in-vivo sensing device during an acquisition period. Batches of the data signal may be transmitted from the data recorder to a receiver, as soon as a batch has been received by the data recorder. The batches of data signal received by the receiver may be downloaded to the workstation as soon as each batch is received by the receiver. Signals are typically transmitted from the data recorder to the receiver through wireless transmission techniques such as cellular transmission, WLAN (Wireless Local Area Network) transmission, BT (BlueTooth) transmission and Wimax (Worldwide interoperability for Microwave Access) transmission.

Claims

1. A method for transmitting data by an in-vivo sensing device comprising:

sensing an in-vivo region of a body lumen by an in-vivo sensing device to produce sensed data during an acquisition period;

capturing said sensed data by the in-vivo sensing device;

transmitting the captured data by the in-vivo sensing device and receiving the transmitted data by a data recorder;

temporarily storing the received data in the data recorder until a specified amount of data has been stored, wherein said specified amount of data constitutes a batch of data;

transmitting the batch of data by the data recorder in real time to a workstation; and

processing the batch of data in the workstation.

2. The method according to claim 1, wherein the sensed data includes image frames.

3. The method according to claim 1, comprising determining when to transmit a batch of stored data.

4. A system for transmitting in-vivo data comprising:

an in-vivo sensing device to sense an in-vivo region of a body lumen, said in-vivo device comprising a sensor and a transmitter;

a data recorder to receive in-vivo data from the in-vivo device, said data recorder comprising a storage unit for temporarily storing a batch of received data and a transmitter to transmit the batch of received data in real time; and

a workstation comprising a receiver to receive the data batch and a processor to process it.

5. The system according to claim 4 wherein the data recorder comprises a compression unit to compress the in-vivo data.

6. The system according to claim 5 wherein the compression unit comprises a smart-select unit to select image frames for transmission to the workstation.

7. The system according to claim 4 wherein the data recorder comprises a telemetry storage unit for storing telemetry information of a received data signal.

8. The system according to claim 4 further comprising a receiver, wherein said receiver is to receive data from the data recorder and to transmit it to the workstation, said receiver comprising a processor for processing the data before transmitting it to the workstation.

9. The system according to claim 4 wherein the data recorder is hand-held.
