Patent ID: 8251896

Claim:
An endoscopic imaging device, the device comprising: an insertion tube comprising a proximal end and a distal end having a distal tip; an annular illumination tube comprising an annular illumination fiber for illuminating a vessel during endoscopy, the annular illumination tube being disposed through the insertion tube to the distal end thereof; a first imaging tube comprising a first imaging fiber, the first imaging fiber disposed within the annular illumination tube; a second imaging tube comprising a second imaging fiber, the second illumination fiber being disposed adjacent the first imaging tube along substantially a length of the annular illumination tube; and a control system in communication with the insertion tube for receiving data of a vessel and for imaging the data during operation of the device, wherein the control system is operable to receive video data of gross video images and image data of cellular images of the vessel from the insertion tube; convert the video data to 3-dimensional imaging data in cylindrical coordinates, and to define cylinder image data; and convert the cylinder image data to a 2-dimensional map for imaging tissues on both a gross level and a cellular level; and, an optical field of view of the first imaging tube is larger than an optical field of view of the second imaging tube.
