Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Four‐dimensional cone‐beam CT (4D CBCT) incorporates oversampling of 3D data to reconstruct multi‐phase CBCT data sets representing distinct phases of the breathing cycle based on a diaphragmatic correlate of respiratory motion. Motion artifacts and blurring can be reduced relative to three‐dimensional cone‐beam (3D CBCT), allowing ...

Energy dependence of the GAFCHROMIC LD‐V1 in the diagnostic radiographic modalities
Journal of Applied Clinical Medical Physics, EarlyView.Abstract The GAFCHROMIC LD‐V1 radiochromic film is widely used in dosimetry because it can provide high‐resolution two‐dimensional dose distributions without processing. This study aimed to evaluate the response characteristics at different effective energies, from the low‐energy range of mammography to the high‐energy range of computed tomography. Net

Deconstructing Photospheric Spectral Lines in Solar and Stellar Flares
The Astrophysical JournalDuring solar flares, spectral lines formed in the photosphere have been shown to exhibit changes to their profiles despite the challenges of energy transfer to these depths.
