FBG-Based Position Estimation of Highly Deformable Continuum Manipulators: Model-Dependent vs. Data-Driven Approaches
Shahriar Sefati, Rachel Hegeman, Farshid Alambeigi +2
Conventional shape sensing techniques using Fiber Bragg Grating (FBG) involve finding the curvature at discrete FBG active areas and integrating curvature over the length of the co…
FBG-Based Control of a Continuum Manipulator Interacting With Obstacles
Shahriar Sefati, Ryan Murphy, Farshid Alambeigi +4
Tracking and controlling the shape of continuum dexterous manipulators (CDM) in constraint environments is a challenging task. The imposed constraints and interaction with unknown…
Inroads Toward Robot-Assisted Internal Fixation of Bone Fractures Using a Bendable Medical Screw and the Curved Drilling Technique
Farshid Alambeigi, Mahsan Bakhtiarinejad, Armina Azizi +4
Internal fixation is a common orthopedic procedure in which a rigid screw is used to fix fragments of a fractured bone together and expedite the healing process. However, the rigid…
Augmented Reality-based Feedback for Technician-in-the-loop C-arm Repositioning
Mathias Unberath, Javad Fotouhi, Jonas Hajek +5
Interventional C-arm imaging is crucial to percutaneous orthopedic procedures as it enables the surgeon to monitor the progress of surgery on the anatomy level. Minimally invasive…
Exploiting Partial Structural Symmetry For Patient-Specific Image Augmentation in Trauma Interventions
Javad Fotouhi, Mathias Unberath, Giacomo Taylor +7
In unilateral pelvic fracture reductions, surgeons attempt to reconstruct the bone fragments such that bilateral symmetry in the bony anatomy is restored. We propose to exploit thi…
Closing the Calibration Loop: An Inside-out-tracking Paradigm for Augmented Reality in Orthopedic Surgery
Jonas Hajek, Mathias Unberath, Javad Fotouhi +6
In percutaneous orthopedic interventions the surgeon attempts to reduce and fixate fractures in bony structures. The complexity of these interventions arises when the surgeon perfo…
