Patent ID: 7572284

Claim:
A method for automated localization of lesions in the gastrointestinal tract for treatment using laser light from an endorobot, comprising: recording surface images of the gastrointestinal tract using a camera of the endorobot; transmitting the surface images to a computer; analyzing the surface images on the basis of lesion-specific features with regard to lesions to be irradiated; computing control signals on the basis of a detected lesion; transmitting the control signals to at least one of an endorobot steering device and a laser system located in the endorobot; and adjusting a computed laser-beam orientation and size of the laser irradiation area by at least one of the endorobot steering device and the laser system, on the basis of the control signals; wherein movement of the laser beam is effected by a magnetic-field steering system, in which the laser is coupled to at least one of a movable magnet and magnetizable material that is not used for navigation of the endorobot and that is capable of being at least one of tilted and displaced by applying an external magnetic field.
