CBCT Dose Is Reduced with Angular Tube Current Modulation While Maintaining Image Quality and Reducing Photon Starvation Artifacts.

PURPOSE This study evaluated whether scout-derived angular tube current modulation (ATCM) in cone beam computed tomography (CBCT) can reduce radiation dose while preserving image quality. ATCM is routine in helical CT but remains absent from clinical CBCT and is largely unexplored in the literature. METHODS A project...

Dual-energy cone-beam CT improves iodine contrast and Hounsfield unit value stability in the maxillofacial region: a phantom study

Although DE-CBCT with VMI and frequency splitting improves HU agreement with CT, slightly improves soft tissue visualization, and reduces artifacts in head and neck phantom imaging, it did not reveal any additional targets compared with routine CBCT.
