Optimal radiotherapy strategy for primary or recurrent fibromatosis and long-term results. [PDF]

open access: yesPLoS ONE, 2018
PURPOSE:Although locally invasive or recurrent fibromatosis is primarily treated with surgery, radiotherapy (RT) produces local control for recurrent/unresectable tumors or those with positive surgical margins.

Modification of intergrain connectivity, upper critical field anisotropy, and critical current density in ion irradiated MgB2 films

open access: yes, 2005
We study the effect of 100 MeV Silicon and 200 MeV Gold ion irradiation on the inter and intra grain properties of superconducting thin films of Magnesium Diboride.

Integral dose during constant velocity motion near a space power reactor [PDF]

open access: yes, 1972
The dose rate in a rotationally-symmetric radiation field near a space power reactor is assumed to be inversely proportional to separation distance squared and directly proportional either to a constant or a constant times the sine-cubed of a polar angle.

On voxel-by-voxel accumulated dose for prostate radiation therapy using deformable image registration. [PDF]

open access: yes, 2015
Since delivered dose is rarely the same with planned, we calculated the delivered total dose to ten prostate radiotherapy patients treated with rectal balloons using deformable dose accumulation (DDA) and compared it with the planned dose.

Out-of-field dose measurements in a water phantom using different radiotherapy modalities

open access: yesPhysics in Medicine and Biology, 2012
This investigation focused on the characterization of the lateral dose fall-off following the irradiation of the target with photons, protons and carbon ions. A water phantom was irradiated with a rectangular field using photons, passively delivered protons as well as scanned protons and carbon ions. The lateral dose profile in the depth of the maximum

Assessment of leakage dose in vivo in patients undergoing radiotherapy for breast cancer

open access: yesPhysics and Imaging in Radiation Oncology, 2018
Background and purpose: Accurate quantification of the relatively small radiation doses delivered to untargeted regions during breast irradiation in patients with breast cancer is of increasing clinical interest for the purpose of estimating long-term ...

Commissioning and out-of-field dose characterisation of the Elekta Unity MRL

open access: yes, 2022
Marcus Powers commissioned the Southern Hemisphere's first clinical MRI-guided Linear Accelerator and assessed radiation doses during treatments with the machine. He found it was suitable for the provision of cancer therapy and revealed potential unintended radiation deposition to distal patient regions.

Measurements of the Secondary Electron Emission of Some Insulators

open access: yes, 2013
Charging up the surface of an insulator after beam impact can lead either to reverse sign of field between the surface and collector of electrons for case of thick sample or appearance of very high internal field for thin films.

An Investigation into the Radiation Damage of the Silicon Detectors of the H1-PLUG Calorimeter within the HERA environment [PDF]

open access: yes, 1995
The silicon detectors used in the H1-PLUG calorimeter have shown increasing aging effects during the '94 run period of the electron proton storage ring HERA.

Dosimetric characteristics of a new linear accelerator under gated operation. [PDF]

open access: yes, 2006
Respiratory gated radiotherapy may allow reduction of the treatment margins, thus sparing healthy tissue and/or allowing dose escalation to the tumor. However, current commissioning and quality assurance of linear accelerators do not include evaluation ...
