Complementary Textures. A Novel Approach to Object Alignment in Mixed Reality
Alejandro Martin-Gomez, Alexander Winkler, Rafael de la Tijera Obert +4
Alignment between real and virtual objects is a challenging task required for the deployment of Mixed Reality (MR) into manufacturing, medical, and construction applications. To fa…
From Perspective X-ray Imaging to Parallax-Robust Orthographic Stitching
Javad Fotouhi, Xingtong Liu, Mehran Armand +2
Stitching images acquired under perspective projective geometry is a relevant topic in computer vision with multiple applications ranging from smartphone panoramas to the construct…
Spatiotemporal-Aware Augmented Reality: Redefining HCI in Image-Guided Therapy
Javad Fotouhi, Arian Mehrfard, Tianyu Song +5
Suboptimal interaction with patient data and challenges in mastering 3D anatomy based on ill-posed 2D interventional images are essential concerns in image-guided therapies. Augmen…
On the Effectiveness of Virtual Reality-based Training for Robotic Setup
Arian Mehrfard, Javad Fotouhi, Tess Forster +5
Virtual Reality (VR) is rapidly increasing in popularity as a teaching tool. It allows for the creation of a highly immersive, three-dimensional virtual environment intended to sim…
Exploring Partial Intrinsic and Extrinsic Symmetry in 3D Medical Imaging
Javad Fotouhi, Giacomo Taylor, Mathias Unberath +5
We present a novel methodology to detect imperfect bilateral symmetry in CT of human anatomy. In this paper, the structurally symmetric nature of the pelvic bone is explored and is…
A Comparative Analysis of Virtual Reality Head-Mounted Display Systems
Arian Mehrfard, Javad Fotouhi, Giacomo Taylor +3
With recent advances of Virtual Reality (VR) technology, the deployment of such will dramatically increase in non-entertainment environments, such as professional education and tra…
Reflective-AR Display: An Interaction Methodology for Virtual-Real Alignment in Medical Robotics
Javad Fotouhi, Tianyu Song, Arian Mehrfard +8
Robot-assisted minimally invasive surgery has shown to improve patient outcomes, as well as reduce complications and recovery time for several clinical applications. While increasi…
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…
X-ray-transform Invariant Anatomical Landmark Detection for Pelvic Trauma Surgery
Bastian Bier, Mathias Unberath, Jan-Nico Zaech +5
X-ray image guidance enables percutaneous alternatives to complex procedures. Unfortunately, the indirect view onto the anatomy in addition to projective simplification substantial…
DeepDRR -- A Catalyst for Machine Learning in Fluoroscopy-guided Procedures
Mathias Unberath, Jan-Nico Zaech, Sing Chun Lee +4
Machine learning-based approaches outperform competing methods in most disciplines relevant to diagnostic radiology. Interventional radiology, however, has not yet benefited substa…
Double Your Views - Exploiting Symmetry in Transmission Imaging
Alexander Preuhs, Andreas Maier, Michael Manhart +3
For a plane symmetric object we can find two views - mirrored at the plane of symmetry - that will yield the exact same image of that object. In consequence, having one image of a…
On-the-fly Augmented Reality for Orthopaedic Surgery Using a Multi-Modal Fiducial
Sebastian Andress, Alex Johnson, Mathias Unberath +6
Fluoroscopic X-ray guidance is a cornerstone for percutaneous orthopaedic surgical procedures. However, two-dimensional observations of the three-dimensional anatomy suffer from th…
Plan in 2D, execute in 3D: An augmented reality solution for cup placement in total hip arthroplasty
Javad Fotouhi, Clayton P. Alexander, Mathias Unberath +9
Reproducibly achieving proper implant alignment is a critical step in total hip arthroplasty (THA) procedures that has been shown to substantially affect patient outcome. In curren…
X-ray In-Depth Decomposition: Revealing The Latent Structures
Shadi Albarqouni, Javad Fotouhi, Nassir Navab
X-ray radiography is the most readily available imaging modality and has a broad range of applications that spans from diagnosis to intra-operative guidance in cardiac, orthopedics…
