Certain embodiments include an endoscope and methods for imaging using the endoscope. The endoscope may include an imaging channel and a tip positioned at one end of the imaging channel, the tip adapted to collect light from a field of view that extends 360° around at least a portion of the endoscope and to transmit the light to the imaging channel. Certain embodiments may also utilize various sensors, controllers and processing mechanisms to record and process images into a representation, move the endoscope in and out of the endometrial cavity, and to biopsy a portion of the endometrium.

A method as in claim 1, wherein: processing the series of images comprises selecting a ring-like segment from one of the images and applying a transformation to convert the ring-like segment into a first rectangular segment, and selecting a ring like segment from a second of the images and applying a transformation to convert the ring-like segment into a second rectangular segment; and combining at least a portion of the processed images comprises combining the first rectangular segment and the second rectangular segment. 3. A method as in claim 1, wherein the field of view of the endoscope extends 360 degrees around at least a portion of the endoscope. 4. A method as in claim 1, wherein the endoscope includes at least one of a reflective element and a refractive element. 5. A method as in claim 1, further comprising obtaining images using a specific wavelength or a specific bandwidth of light. 6. A method as in claim 1, further comprising obtaining images using at least one of visible, ultra-violet and infrared wavelength light. 7. A method as in claim 1, further comprising obtaining images using at least one of reflected imaging, scattered light imaging and florescence imaging of the organ system. 8. A method as in claim 1, further comprising a control system adapted to move the endoscope in the organ system, the control system also adapted to measure the change in position of the endoscope as it moves. 9. A method as in claim 1, further comprising illuminating the organ system with broadband light and recording the images with an image sensor positioned outside of the organ system. 10. A method as in claim 9, wherein the image sensor includes a CCD. 11. A method as in claim 1, further comprising illuminating the organ system with light of a particular wavelength or a particular band of wavelengths and recording the images with an image sensor positioned outside of the organ system. 12. A method as in claim 1, further comprising a control system adapted to position the endoscope to a desired location within the organ system based on the map of the endometrial lining of the uterus of the patient. 13. A method as in claim 1, further comprising capturing images using an image sensor positioned within the organ system and transmitting the images to a device positioned outside of the organ system. 14. A method as in claim 13, wherein the image sensor comprises an electrical transducer. 15. A method as in claim 1, further comprising providing a control system to locate a specific area of interest in the endometrial lining based on the map of the endometrial lining of the uterus of the patient, and using the control system to position a biopsy apparatus to obtain a biopsy in the specific area of interest. 16. A method as in claim 15, wherein the biopsy apparatus comprises a collector and plunger system. 17. A method as in claim 15, wherein the biopsy comprises at least one biopsy technique selected from an optical biopsy technique and a physical biopsy technique. 18. A method as in claim 1, further comprising: providing an imaging sensor to control the timing of the obtaining of images image; detecting changes in position of the omni-directional tip of the endoscope within the collapsed cavity formed by the uninsufflated uterus of the patient using a position sensor; and triggering the imaging sensor to obtain an image upon receiving a signal from the position sensor indicating that the omni-directional tip of the endoscope has moved a predetermined distance within the collapsed cavity formed by the uninsufflated uterus of the patient after a first image has been obtained. 19. A method as in claim 18, further comprising: obtaining a plurality of additional images of the collapsed cavity formed by the uninsufflated uterus of the patient using the imaging device, wherein the omni-directional tip of the endoscope is moved in the collapsed cavity formed by the uninsufflated uterus of the patient between each of the additional images, the additional images each including distortion created by the imaging device, processing the additional images to remove at least a portion of the distortion in each of the images; and combining at least a portion of each of the additional images together with the at least a portion of the first image and the at least a portion of the second image. 20.
