Hounsfield Unit characterization and dose calculation on a C‐arm linac with novel on‐board cone‐beam computed tomography feature and advanced reconstruction algorithms

Journal of Applied Clinical Medical Physics, Volume 26, Issue 8, August 2025.
Abstract Purpose Current cone‐beam computed tomography (CBCT) on‐board c‐arm linear accelerators (linacs) lack CT number precision sufficient for dose calculation due to increased scatter from the cone geometry. This investigation evaluated CT number and dose calculation accuracy in‐phantom on a novel on‐board CBCT unit with potential for improved dose

Low‐Frequency Raman Spectroscopy of Polymers

Macromolecular Chemistry and Physics, Volume 226, Issue 15, August 4, 2025.
Recent advances have made low‐frequency Raman spectroscopy accessible to the wider scientific community. This review discusses how low‐frequency Raman is particularly useful for researchers investigating polymers because the technique can help determine both the local and long‐range structure of materials, their thermodynamic properties, and their ...
