Cone-beam computed tomography (CBCT) systems specifically designed and manufactured for dental, maxillofacial imaging (MFI) and otolaryngology (OLR) applications have been commercially available in the United States since 2001 and have been in widespread clinical use since. Until recently, there has been a lack of professional guidance available for medical physicists about how to assess and evaluate the performance of these systems and about the establishment and management of quality control (QC) programs. The owners and users of dental CBCT systems may have only a rudimentary understanding of this technology, including how it differs from conventional multidetector CT (MDCT) in terms of acceptable radiation safety practices.

- Directional leads in deep brain stimulation (DBS) are important for effective treatment, and accurately identifying their orientation is crucial for programming, yet traditional imaging methods struggle with this task.
- This study developed a reliable method using standard imaging techniques and accessible software to determine the orientation of directional leads based on postoperative CT scans and x-rays, utilizing unique artifacts created by the leads.
- The identified streak artifacts on imaging can help infer the lead orientation, enabling better treatment planning by providing clear directional information that can be verified with additional x-ray comparisons.
Purpose: Novel CT reconstruction techniques strive to maintain image quality and processing efficiency. The purpose of this study is to investigate the impact of a newer hybrid iterative reconstruction technique, Adaptive Statistical Iterative Reconstruction-V (ASIR-V), in combination with various CT scan parameters on the semi-automated quantification using various lung nodules.
Methods: A chest phantom embedded with eight spherical objects was scanned using varying CT parameters such as tube current and ASIR-V levels.
