  • Publication number: 20210369355
    Abstract: An endoscope imaging system comprises a robotic controlled steerable catheter and an imaging device removably arranged in a tool channel of the catheter. One or more sensors or markers are configured to map a positional relation of the catheter with respect to an orientation of the imaging device. A controller drives the steerable catheter to manipulate the distal end thereof, while the imaging device acquires an image of a subject or sample. While the imaging device acquires the image, a processor calculates a change in positional relation of the catheter with respect to the orientation of the imaging device based on information provided by the one or more sensors or markers. An output unit provides an indication for remapping the orientation of the steerable catheter with respect to the orientation of the imaging device.
