1. A method of medical imaging device guidance, the method comprising: receiving a volumetric medical image, the volumetric medical image including a plurality of image slices; determining a density of content within the volumetric medical image based at least in part on an intensity value of voxels associated with the content within the volumetric medical image; receiving an indication of a target location within the volumetric medical image; identifying based at least in part on the determined density of the content obstructing objects within the volumetric medical image having a density that does not satisfy a density threshold, wherein the density threshold is based at least in part on one or more imaging characteristics of a medical imaging device; determining a plurality of direct pathways from an approach region of the volumetric medical image to the target location that pass through at least two of the plurality of image slices and that do not pass through the obstructing objects; and causing a display to concurrently display: the volumetric medical image, and a plurality of emplacements on the approach region of the volumetric medical image for emplacement of the medical imaging device based at least in part on the determined plurality of direct pathways.
