US Patent 11317974 Systems and methods for navigation and visualization

Systems and methods for visualization of a surgical site are disclosed. An imaging device provides image data of the surgical site. A computing device detects, in the image data, at least one obstruction. The computing device filters the image data to remove the at least one obstruction by being configured to alter pixels related to the at least one obstruction based on at least one of (i) one or more buffered frames and (ii) one or more pixels adjacent to the pixels related to the at least one obstruction. The computing device generates an output from the filtered image data. A display device presents the output for visualization of the surgical site.
