METHOD AND SYSTEM FOR SUPER-RESOLUTION OF CONFOCAL IMAGES ACQUIRED THROUGH AN IMAGE GUIDE, AND DEVICE USED FOR IMPLEMENTING SUCH A METHOD

摘要

The invention concerns a method for increasing the resolution of confocal images acquired through an image guide whereof the distal end is associated with an optical head for focusing the laser beam emitted by the image guide in an observation object. The invention is characterized in that for a given position of the optical head, said method comprises the following steps: producing a plurality of acquisitions through the image guide, each acquisition being produced for a specific spatial shift of said distal end of the guide image relative to the optical head which remains stationary; transforming the data of each acquisition into a point cloud; registering each scatter plot relative to a point cloud taken as reference; superimposing the thus registered point clouds; and reconstructing a final image from said superimposition. Advantageously, a controlled piezoelectric tube is used arranged about the distal end of the image guide to shift the latter.
