Automatic Annotation of Hip Anatomy in Fluoroscopy for Robust and Efficient 2D/3D Registration
Robert Grupp, Mathias Unberath, Cong Gao +7
Fluoroscopy is the standard imaging modality used to guide hip surgery and is therefore a natural sensor for computer-assisted navigation. In order to efficiently solve the complex…
Fast and Automatic Periacetabular Osteotomy Fragment Pose Estimation Using Intraoperatively Implanted Fiducials and Single-View Fluoroscopy
Robert Grupp, Ryan Murphy, Rachel Hegeman +6
Accurate and consistent mental interpretation of fluoroscopy to determine the position and orientation of acetabular bone fragments in 3D space is difficult. We propose a computer…
Pelvis Surface Estimation From Partial CT for Computer-Aided Pelvic Osteotomies
Robert Grupp, Yoshito Otake, Ryan Murphy +3
Computer-aided surgical systems commonly use preoperative CT scans when performing pelvic osteotomies for intraoperative navigation. These systems have the potential to improve the…
Smooth Extrapolation of Unknown Anatomy via Statistical Shape Models
Robert Grupp, Hsin-Hong Chiang, Yoshito Otake +4
Several methods to perform extrapolation of unknown anatomy were evaluated. The primary application is to enhance surgical procedures that may use partial medical images or medical…
Pose Estimation of Periacetabular Osteotomy Fragments with Intraoperative X-Ray Navigation
Robert B. Grupp, Rachel A. Hegeman, Ryan J. Murphy +5
Objective: State of the art navigation systems for pelvic osteotomies use optical systems with external fiducials. We propose the use of X-Ray navigation for pose estimation of per…
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…
