In vitro Dosimetric Study of Biliary Stent Loaded with Radioactive 125I Seeds

open access: yesChinese Medical Journal, 2017
Background: A novel radioactive 125I seed-loaded biliary stent has been used for patients with malignant biliary obstruction. However, the dosimetric characteristics of the stents remain unclear.

Different germanium dopant concentration and the thermoluminescence characteristics of flat Ge-doped optical fibres [PDF]

open access: yes, 2017
The influence of elevated germanium concentration on the thermoluminesence characteristics of a novel form of fabricated flat optical fibre was examined. All the samples were irradiated with two nominal photon energies (6 MV and 10 MV) and 1.25 MeV gamma

Experimental verification of acuros XB in the presence of lung-equivalent heterogeneities [PDF]

open access: yes, 2017
Acuros XB (AXB) is a deterministic algorithm that directly accounts for the effects of heterogeneities and improves the accuracy of photon dose calculations in radiotherapy. Nevertheless, the accuracy of AXB inside lung has not been yet fully examined by

Radiation induced vaporization of exoskeletal droplets as potential x‐ray acoustic contrast agents

open access: yesMedical Physics, Volume 52, Issue 8, August 2025.
Abstract Background In vivo dosimetry is a crucial component of ensuring accurate and safe radiation therapy (RT) delivery, but many existing techniques face challenges such as low signal‐to‐noise ratio (SNR), which can limit their clinical applicability.

A measurement of the radiation dose to LDEF by passive dosimetry [PDF]

open access: yes
The results from a pair of thermoluminescent dosimeter experiments flown aboard the Long Duration Exposure Facility (LDEF) show an integrated dose several times smaller than that predicted by the NASA environmental models for shielding thicknesses much ...

Dosimetric characteristics of fabricated Ge-doped silica optical fibre for small-field dosimetry

open access: yesResults in Physics, 2019
We study 3 mm long germanium-doped (Ge-doped) silica fibres for small-field dosimetry, seeking to overcome spatial resolution and charged-particle disequilibrium issues, also any associated dose deviation from that of computerised treatment plan dose ...

Evaluation and Comparison of Entrance Skin Dose in the Imaging of Hip Region Using Computed Tomography (CT) Scan and Stereoradiography

open access: yesمجله دانشکده پزشکی اصفهان, 2019
Background: Extensive use of computed tomography (CT)-scan imaging is associated with an increase in cumulative dose. Stereoradiography by electro-optical system (EOS) is an X-ray imaging technology that can reduce patient absorption dose, and increase ...
