In non-destructive testing, computed tomography (CT) is increasingly used for dimensional measurement tasks such as the industrial inspection of work pieces. Besides the determination of the measurement uncertainty, the improvement of the image quality is subject of current research, in order to establish CT as a measuring device. 1. Cone-Beam CT and Metrology Dimensional measurement with CT ha...

Purpose An important factor when considering the use of interventional cone beam computed tomography (CBCT) imaging during cardiac procedures is trade-off between dose and image quality. Accordingly, Adaptive CaRdiac cOne BEAm Tomography (ACROBEAT) presents an alternative acquisition method, adapting gantry velocity projection rate CBCT systems in accordance with a patient’s electrocardiogram (...

This is a case report on stereotaxic (Stereotactic Body Radiotherapy-SBRT) for lung cancer located in the left lower lobe (Segment 6, S6). There have been no reports on marked displacement of the peripheral lung cancer during radiotherapy. A pulmonary nodule was discovered on computed tomography (CT) conducted for a persistent cough in an 87-year-old male. According to diagnostic imaging, this ...

Objective: In cases of stent-assisted coil (SAC) embolization, visualization of stents with cone-beam CT is interfered significantly by the coil mass with streak artifacts. Metal artifact reduction (MAR), which is the algorithm for contrastenhanced cone-beam CT, improves visualization of stents. We analyzed our cases of SAC embolization and report efficacy of MAR. Materials and Methods: We revi...
