Abstract: A processor-implemented method includes accessing or acquiring one or more images from a medical imaging device. The processor-implemented method also includes receiving an indication of one or more constraints associated with one or more physical characteristics of the medical imaging device, an interventional device, or both, and receiving an indication of a target point in the one or more images. The target point may specify an intended location of the interventional device. The processor-implemented method also includes determining corresponding reachability regions for each of the one or more images based on the target point and the one or more constraints. Each corresponding reachability region includes reachable paths for the interventional device between one or more reachable entry points and the target point. The processor-implemented method also includes overlaying the corresponding reachability regions upon each of the one or more images and displaying the one or more images.

Abstract: An x-ray imaging system and method of operation includes a gantry having an x-ray source and an x-ray detector alignable with the x-ray source, along with an image processing system operably connected to the gantry and including a processing unit for processing the x-ray image data from the detector to form x-ray images. The processing unit is configured to determine a position of at least two radiopaque markers located on an object within the anatomy of a patient, where the at least two radiopaque markers identify a proximal end of the object and a distal end of the object. The processing unit can then form one or more x-ray images of the object and the anatomy, and present at least two different indicators representing the radiopaque markers within the one or more x-ray images on the display to provide anatomical orientation information regarding the object within the patient anatomy.
