摘要：
The invention pertains to an apparatus and methods of a medical imaging device for obtaining images from the walls of luminal organs or a surgical cavity. The invention is a rigid enclosure that is capable of passage through luminal organs or introduction into surgical cavities, and obtains images by rapidly scanning a focused light beam on the tissue to be imaged and receiving light from the tissue. The invention has at least one beam scanning mechanism and has multiple embodiments of scanning and focusing optics at different regimes of numerical aperture. The invention also describes methods for correcting inaccurate beam scanning. The device is capable of performing imaging, image guided therapy, tissue excision, or other interventional procedures.
