Secondary cancer risk in head‐and‐neck cancer patients: A comparison of RBE‐weighted proton therapy and photon therapy

Medical Physics, EarlyView.
Abstract Background Secondary cancer is a serious side effect from external beam radiotherapy (EBRT). Conventional EBRT is performed using a beam of photons, however, due to their ability to produce more conformal dose distributions, the use of protons is becoming more wide‐spread.

Optical surface information‐based respiratory phase‐sorting and motion‐incorporated reconstruction for SPECT imaging

Medical Physics, EarlyView.
Abstract Background Respiratory motion during the single photon emission computed tomography (SPECT) acquisition can cause blurring artifacts in the reconstructed images, leading to inaccurate estimates for activity and absorbed doses. Purpose To address the impact of respiratory motion, we utilized a new optical surface imaging (OSI) system to extract

Accuracy of a helium‐beam radiography system based on thin pixel detectors for an anthropomorphic head phantom

Medical Physics, EarlyView.
Abstract Background Ion‐beam radiography is a promising technique to verify the range of ion‐beam radiotherapy treatments regularly. To detect and quantify the water‐equivalent thickness (WET) of potential anatomical changes, ion‐beam radiographs must provide a sufficient WET accuracy on the level of 1%.

Structure and Migration Mechanisms of Oxygen Interstitial Defects in β‐Ga2O3

physica status solidi (b), EarlyView.
The structures and diffusion mechanisms of interstitial oxygen in different charge states in β‐Ga2O3 are extensively studied using density functional theory. The results provide a detailed map of the potential energy surface for oxygen interstitials in β‐Ga2O3 and demonstrate how these ions migrate between different rings in the structure.

Ground-based gamma-ray astronomy [PDF]

AIP Conference Proceedings, 2000
Ground-based gamma-ray astronomy has become an active astrophysical discipline with four confirmed sources of TeV gamma rays, two plerionic supernova remnants (SNRs) and two BL Lac objects (BL Lacs). An additional nine objects (one plerion, three shell-type SNRs, one X-ray binary, and four BL Lacs) have been detected but have not been confirmed by ...
