Clinical implementation of cone-beam tomography has been hampered by the lack of two-
dimensional electronic X-ray detectors that can encompass the full width of the body. We …

Objective: Intraoperative fluoroscopy is a valuable tool for visualizing underlying bone and
surgical tool positions in orthopedic procedures. Disadvantages of this technology include …

Three‐dimensional skeletal movement is often impossible to accurately quantify from
external markers. X‐ray imaging more directly visualizes moving bones, but extracting 3‐D …

Closed surgical techniques for the internal fixation of femoral fractures require orthopaedic
surgeons to work in close proximity to X-rays. In addition to the occupational health risk this …

A better knowledge of the kinematics behavior of total knee replacement (TKR) during
activity still remains a crucial issue to validate innovative prosthesis designs and different …

This paper describes an ongoing project to develop a computer-integrated system to assist
surgeons in revision total hip replacement (RTHR) surgery. In RTHR surgery, a failing …

X‐ray image intensifiers (XRIIs) have many applications in diagnostic imaging including
acquisition of near‐real‐time projection images of the intracranial and coronary vasculature …

Describes new methods for rigid registration of a preoperative computed tomography (CT)-
scan image to a set of intraoperative X-ray fluoroscopic images, for guiding a surgical robot …

A method to correct for geometric image distortion in the x‐ray imaging chain, so‐called
dewarping, has been developed. A global two‐dimensional polynomial model of which the …

We describe a new method to cut a precise, high-quality femoral cavity in Revision Total Hip
Replacement surgery (RTHR) using a surgical robot and an intra-operative C-arm …
