Abstract

A robotic endoscopic system and method confirm whether a tool has reached a target region within a subject using tomosynthesis. While the tool is advanced into the target region, a fluoroscopic imager acquires a plurality of images, and a three-dimensional (3D) fluoroscopic image is reconstructed from the plurality of images. A first slice is identified from the 3D fluoroscopic image in which the target region is in focus and a second slice is identified in which the tool is in focus, and a depth coordinate is determined for each. A difference between the coordinates is compared with a threshold derived from a dimension of the target region to determine, in a quantitative manner, whether the tool is positioned within the target region.
