High-resolution cone beam CT for evaluation of vascular channel in intracranial partial thrombosed aneurysm [PDF]

, 2018
2018-05The authors present a 60-year-old man with a partially thrombosed, intracranial vertebral artery aneurysm. A vascular channel in intra-aneurysmal thrombus was effectively identified with high-resolution cone beam CT (DynaCT Micro: Siemens Medical ...

Concrescence: Cone-Beam Computed Tomography Imaging Perspective

Case Reports in Dentistry, 2016
Concrescence is a form of twinning, formed by the confluence of cementum of two teeth at the root level. The diagnosis of concrescence has largely relied on the conventional 2D imaging.

Geometry Calibration of a Modular Stereo Cone-Beam X-ray CT System

Journal of Imaging, 2021
Compared to single source systems, stereo X-ray CT systems allow acquiring projection data within a reduced amount of time, for an extended field-of-view, or for dual X-ray energies. To exploit the benefit of a dual X-ray system, its acquisition geometry

Bone Densitometric Analysis using Cone Beam Computed Tomography (Cone Beam CT) and Computed Tomography (CT): Establishing the Correlation between Predicted and Actual Values

Advanced Biomedical Research
Background: One of the major drawbacks of cone beam computed tomography (cone beam CT) is that unlike CT, the gray density values obtained from cone beam CT are relative, and not absolute as obtained in the case of CT.

A Characteristic of Angiographic Cone-beam CT

Japanese Journal of Radiological Technology, 2009
Angiographic cone-beam CT, called DynaCT by SIEMENS, is a 3D imaging tool reconstructed from projection data by a rotational C-arm with a flat panel detector. It can visualize low-contrast objects such as soft tissue or small vessels as well as high-contrast structures such as enhanced vessels or bone.
