Abstract

The present invention provides a system and method for obtaining in vivo images. The system contains an imaging system and a transmitter for transmitting signals from a camera to a receiving system located outside a patient.

Claims

1. An in-vivo imaging device comprising:

an imager;

an illumination source; and

a transmitter to transmit images at a rate of two to eight frames per second.

2. The device of claim 1, wherein the transmitter is to operate at frequencies of 432 to 434 MHz.

3. The device of claim 1, wherein transmitter has an input bandwidth of more than 1.35 Megabit per second.

4. The device of claim 1, comprising an optical window.

5. The device of claim 1, comprising an optical system.

6. The device of claim 5, wherein said optical system comprises a lens.

7. The device of claim 1, comprising a plurality of illumination sources.

8. The device of claim 1, wherein the illumination source comprises an LED.

9. The device of claim 1, comprising an illumination source provided in a ring around the imager.
