GPU-Based 3D Cone-Beam CT Image Reconstruction for Large Data Volume

International Journal of Biomedical Imaging, 2009
Currently, 3D cone-beam CT image reconstruction speed is still a severe limitation for clinical application. The computational power of modern graphics processing units (GPUs) has been harnessed to provide impressive acceleration of 3D volume image ...

Weight‐bearing computed tomography reveals greater anterior tibial translation and femorotibial rotation than magnetic resonance imaging in chronic anterior cruciate ligament deficiency: A prospective observational study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare anterior tibial translation and femorotibial rotation measurements obtained from conventional supine, non‐weight‐bearing magnetic resonance imaging (MRI) and weight‐bearing computed tomography (WBCT) in patients with chronic anterior cruciate ligament (ACL) tears. Methods WBCT of the knee acquired in full extension and at 30°

Accuracy of Navigated Osteotomies in Rhinoplasty: A Cadaveric Analysis

The Laryngoscope, EarlyView.
Navigation‐guided osteotomies in rhinoplasty demonstrate high accuracy. Both transnasal and percutaneous approaches achieved clinically relevant submillimeter accuracy relative to the planned osteotomy trajectories in cadaveric specimens, as confirmed by direct measurements; although imaging‐based assessments indicated slightly lower precision ...

Hybrid operating room with ceiling mounted imaging system assisted pre-operative and intra-operative lung nodule localization for thoracoscopic resections: a 5-year case series

Journal of Cardiothoracic Surgery
Background Video-assisted thoracoscopic (VATS) lung resections are increasingly popular and localization techniques are necessary to aid resection. We describe our experience with hybrid operating room (OR) cone-beam computed tomography (CT) assisted pre-

Triple-source saddle-curve cone-beam photon counting CT image reconstruction: A simulation study

Zeitschrift für Medizinische Physik
Purpose: The most common detector material in the PC CT system, cannot achieve the best performance at a relatively higher photon flux rate. In the reconstruction view, the most commonly used filtered back projection, is not able to provide sufficient ...

Spiral Cone-beam CT - Successes with Spiral Scans

, 2014
X-ray computed tomography (CT) is instrumental in medicine, industry and homeland security, which depicts internal structures of an object from its shadows projected in a fan-beam or cone-beam from an x-ray source along a appropriate trajectory.

Evaluation of Concordance between Radiation Therapists and Medical Physicists in MR‐Guided Online Adaptive Planning

Precision Radiation Oncology, EarlyView.
Magnetic resonance (MR)‐guided online adaptive radiotherapy requires skill in online adaptive treatment planning. This study demonstrated that radiation therapists, with appropriate training, can consistently produce high‐quality adaptive plans concordant with those created by medical physicists for treatment on a 1.5 Tesla MR‐Linac.
