Development of a 2D dosimetry system based on the optically stimulated luminescence of Al2O3
M.F. Ahmed,S.A. Eller,E Schnell,Salahuddin Ahmad,Mark S. Akselrod,O.D. Hanson,Eduardo G. Yukihara +6 more
TL;DR: A laser-scanning 2D dosimetry system based on the Optically Stimulated Luminescence signal from Al 2 O 3 films was built and demonstrated and results from 6 MV photon beam irradiations from a clinical linear accelerator were compared to radiographic and radiochromic film profiles showing a good qualitative agreement.

Demonstration of 2D dosimetry using Al2O3 optically stimulated luminescence films for therapeutic megavoltage x-ray and ion beams
M.F. Ahmed,N. Shrestha,Salahuddin Ahmad,E Schnell,Mark S. Akselrod,Eduardo G. Yukihara,Eduardo G. Yukihara +6 more
TL;DR: The data obtained show that the OSLD films allow 2D dosimetry with sub-millimetric resolution, with approximately linear photon dose response over a wide dynamic range, no film saturation up to > 76 Gy, and a minimum detectable dose.

Dosimetric comparison between IMRT delivery modes: Step-and-shoot, sliding window, and volumetric modulated arc therapy - for whole pelvis radiation therapy of intermediate-to-high risk prostate adenocarcinoma
T Herman,E Schnell,J Young,Kim Hildebrand,Ozer Algan,Elizabeth Syzek,Terence S. Herman,Salahuddin Ahmad +7 more
TL;DR: Similar target coverage and normal tissue doses were found by the three compared modes and the dosimetric differences were small.

Dosimetric considerations when utilizing Venezia, Capri, Rotte double tandem, and tandem and ring with interstitial needles for the treatment of gynecological cancers with high dose rate brachytherapy
TL;DR: The difference in dosimetry of high dose rate (HDR) brachytherapy treatments between plans using advanced multichannel applicators and simplified base versions was evaluated to allow better target dose conformation and normal tissue dose manipulation.

Plate-specific gain map correction for the improvement of detective quantum efficiency in computed radiography
TL;DR: This study demonstrates that a simple gain-map can be used to correct for the fixed-pattern noise in a given plate and thus improve the DQE of CR imaging over a wide range of frequencies with this technique.
