A fluoroscopic imaging device (110) rotatable about a target area of a patient and configured to acquire a fluoroscopic video of the target area comprising frames of the target area. The frames being captured during rotation of the imaging device about the target area. A computing device (125) configured to determine a pose of the fluoroscopic imaging device for each frame of the fluoroscopic video； construct, from the fluoroscopic video and the pose determined for each frame of the fluoroscopic video, fluoroscopic-based three dimensional volumetric data of the target area； and sharpen or intensify at least one of a portion of the fluoroscopic-based three dimensional volumetric data or at least one frame to identify soft tissue objects using the fluoroscopic-based three dimensional volumetric data.
