Background And Purpose: A novel ring-gantry cone-beam computed tomography (CBCT) imaging system shows improved image quality compared to its conventional version, but its effect on autosegmentation is unknown. This study evaluates the impact of this high-performance CBCT on autosegmentation performance, inter-observer variability, contour correction times and delineation confidence, compared to the conventional CBCT.
Materials And Methods: Twenty prostate cancer patients were enrolled in this prospective clinical study.
Article Synopsis
- The HyperSight high-performance CBCT imaging system provides better Hounsfield unit accuracy and image quality for treatment planning in cancer patients.
- A study compared dose calculation accuracy between HyperSight CBCT and traditional planning CT in prostate and lung cancer cases, evaluating various dose distribution parameters.
- Results showed HyperSight CBCT yielded accurate dose calculations for prostate patients, but breathing motion significantly affected accuracy for lung cancer patients.*
Introduction: Although Cognitive Behavioral Therapy (CBT) is the most often used intervention in forensic treatment, its effectivity is not consistently supported. Interventions incorporating knowledge from neuroscience could provide for more successful intervention methods.
Methods: The current pilot study set out to assess the feasibility and usability of the study protocol of a 4-week neuromeditation training in adult forensic outpatients with impulse control problems.
. Newer cone-beam computed tomography (CBCT) imaging systems offer reconstruction algorithms including metal artifact reduction (MAR) and extended field-of-view (eFoV) techniques to improve image quality. In this study a new CBCT imager, the new Varian HyperSight CBCT, is compared to fan-beam CT and two CBCT imagers installed in a ring-gantry and C-arm linear accelerator, respectively.

The PGNG task has been shown to measure core executive functions (EFs) in a psychometrically sound, brief, and ecologically valid manner.
Objective: To analyze the psychometric properties of the Dutch version of the PGNG task in a convenience sample of nonclinical adults.
