Vacuum gage system for radiation environment [PDF]
, 1969 Hot-cathode ionization gages used to measure high-vacuum pressures are subject to error when ionizing radiation is present. Because this radiation creates additional ions, a second ion gage is mounted near the pressure-measuring gage to detect and ...

Log file‐based quality assurance method for respiratory gating system
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background As medical linear accelerator technology advances, enabling higher dose rate deliveries, hypofractionation regimens has increased. This necessitates respiratory gating systems that synchronize radiation delivery with tumor position, requiring simple rigorous quality assurance (QA) to ensure treatment accuracy and patient safety ...

Machine stability and dosimetry for ultra‐high dose rate FLASH radiotherapy human clinical protocol
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The FLASH effect, induced by ultra‐high dose rate (UHDR) irradiations, offers the potential to spare normal tissue while effectively treating tumors. It is important to achieve precise and accurate dose delivery and to establish reliable detector systems, particularly for clinical trials needed to help the clinical transfer of FLASH‐

Accounting for TLD response to CBCT protocols in external beam radiotherapy dose monitoring
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose LiF thermoluminescent dosimeters (TLDs) are commonly used in radiation therapy to verify the delivered dose. Examples include dose verification for complicated treatment setups or cardiovascular implantable electronic devices (CIEDs). TLDs may be present for both the pre‐treatment imaging kilovoltage (kV) beam and the megavoltage (MV ...
