Abstract While atom probe tomography (APT) offers 3D spatially-resolved compositional characterization at the nanometer scale, individual inspection of large datasets is time demanding and interpretation thereof highly operator-dependent. Recently, decomposition behavior (V,Al)N thin films was investigated by APT. The conventional analysis, employing standard tools from commercial software, lab...

PURPOSE To determine whether postoperative ocular inflammation is less after femtosecond laser-assisted cataract surgery than after conventional phacoemulsification (manual) cataract surgery. SETTING Private clinic, Launceston, Tasmania, Australia. DESIGN Prospective consecutive investigator-masked nonrandomized parallel cohort study. METHODS Consecutive cataract patients who had femtosec...

The variability in width, height, and spatial orientation of a spinal pedicle makes pedicle screw insertion a delicate operation. The aim of the current paper is to describe a computer-assisted surgical navigation system based on fluoroscopic X-ray image calibration and three-dimensional optical localizers in order to reduce radiation exposure while increasing accuracy and reliability of the su...

BACKGROUND Accurate and precise tunnel placement is critical to the success of anterior cruciate ligament (ACL) reconstruction. A new development, computer-assisted surgery, aids in placement of the ACL bone tunnels during surgery. Our hypothesis was that computer-assisted ACL reconstruction would allow more accurate and precise tunnel placement compared with conventional surgery. METHODS In ...

Computer-assisted orthopaedic surgery was born in the 1990s. Nowadays, computer-assisted orthopaedic surgery is used for transpedicular screw fixation and for total knee arthroplasty.Patient-specific instrumentation is one type of computer-assisted surgery based on volumetric images, such as computed tomography or magnetic resonance imaging.In this article, possible applications of patient-spec...
