Weight-bearing cone beam CT scans in the foot and ankle

EFORT Open Reviews, 2018
The 3D anatomical complexity of the foot and ankle and the importance of weight-bearing in diagnosis have required the combination of conventional radiographs and medical CT.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Cone beam CT and stereolithographic model in primary dentition

Annali di Stomatologia, 2021
There are many recognized dental anomalies, among the least common being the “triple tooth”, with a prevalence of 0.02% in the primary dentition. However, such malformation can more easily lead not only to carious pathology, due to dental dysmorphisms ...

Effect of time lapse on the diagnostic accuracy of cone beam computed tomography for detection of vertical root fractures [PDF]

, 2016
Accurate and early diagnosis of vertical root fractures (VRFs) is imperative to prevent extensive bone loss and unnecessary endodontic and prosthodontic treatments.

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

Advanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Adaptive replanning using cone beam CT for deformation of original CT simulation

Journal of Medical Radiation Sciences, 2022
Background During a course of radiation therapy, anatomical changes such as a decrease in tumour size or weight loss can trigger the need for repeating a computed tomography (CT) simulation scan in order to generate a new treatment plan.

Survival prediction of non-small cell lung cancer patients using radiomics analyses of cone-beam CT images.

Radiotherapy and Oncology, 2017
BACKGROUND AND PURPOSE In this study we investigated the interchangeability of planning CT and cone-beam CT (CBCT) extracted radiomic features. Furthermore, a previously described CT based prognostic radiomic signature for non-small cell lung cancer ...

Biomimetic Ion‐Orchestrated Hierarchical Armored Hydrogel Coating for Robust and Multifunctional Surface Protection

Advanced Functional Materials, EarlyView.
Inspired by the skin‐toughening mechanism of marine sponges, an ion‐orchestrated structural engineering strategy is proposed to regulate the surface microstructure of hydrogel coatings, enabling the in situ formation of a robust armor layer that enhances mechanical integrity and provides multifunctional protection by suppressing fouling attachment and ...

Influence of intraoperative conventional fluoroscopy versus cone beam CT on long-term clinical outcome in isolated displaced talar fractures

Journal of Orthopaedic Surgery and Research, 2019
Introduction The objective of the study was to compare the radiologic and clinical outcome of patients with an isolated displaced talus fracture treated intra-operatively with either conventional fluoroscopy or additional cone beam computed tomography ...

Quasi-Exact Helical Cone Beam Reconstruction for Micro CT [PDF]

, 2002
A cone beam micro-CT system is set up to collect truncated helical cone beam data. This system includes a micro-focal X-ray source, a precision computer-controlled X-Y-Z-theta stage, and an image-intensifier coupled to a large format CCD detector.
