Abstract: A method is provided for method for navigating a robotic endoscopic apparatus comprising: (a) navigating the robotic endoscopic apparatus to a target region inside of a body part; (b) acquiring a fluoroscopic image using a fluoroscopic imager when a tool is extended through the robotic endoscopic apparatus into the target region, where the fluoroscopic image comprises a plurality of slices stacked in a depth direction; and (c) identifying a first slice with a first coordinate corresponding to a center of the target region in the depth direction, and a second slice with a second coordinate corresponding to the tool in the depth direction; and (d) determining whether the tool is inside the target region based on a difference between the first coordinate and the second coordinate.

Abstract: A system and method for controlling filament extrusion comprises receiving extrusion path signals that specify a first extrusion path and a second extrusion path for simultaneous execution by a corresponding first print head and second print head, and simultaneously extruding a first filament from the first print head according to the first extrusion path and a first extrusion rate specification, and a second filament from the second print head according to the second extrusion path and a second extrusion rate specification. The first extrusion path and the second extrusion path are specified according to a target coordinate space. In one embodiment, the target coordinate space comprises a cylindrical coordinate space. The system and method advantageously provides faster printing and greater material flexibility for three-dimensional printers.
