“…Acquiring 3-D information from endoscopic images is usually done during an off-line routine, i.e. an image sequence is recorded and subsequently processed to get the desired information about the operation area (Vogt et al, 2005;Thormählen et al, 2002).…”

TOF chips enable the acquisition of distance information via the phase shift of a reference signal and the reference signal reflected in a scene. Transmitting the reference signal via the light conductor of an endoscope and mounting a TOF chip distally enables the acquisition of distance information via an endoscope. The hardware combination of TOF technology and endoscope optics is termed Multisensor-Time-Of-Flight endoscope (MUSTOF endoscope). Utilizing a MUSTOF endoscope in the context of NOTES procedures, enables the direct endoscopic acquisition of 3-D information (NOTES 3D). While hardware issues are currently under investigation, an algorithmic framework is proposed here, dealing with the main points of interest: calibration, registration and reconstruction.
