Abstract
A system comprises a tool and a catheter sized to receive the tool. The system also comprises a processor and a memory having computer readable instructions stored thereon. The computer readable instructions, when executed by the processor, cause the system to receive, via an image sensor of the tool, a plurality of images from within a lumen of the catheter. Each image comprises a plurality of pixels. For each image, a subset of the plurality of pixels associated with a viewable feature is identified. For each image, a likely orientation for the viewable feature is determined based on the identified subset of the plurality of pixels. A composite orientation for the viewable feature is determined based on a combination of the likely orientations of the viewable feature for each image. A rotational offset of the tool relative to the catheter is determined based on the determined composite orientation.
