Characterization of Optically Stimulated Luminescent Detectors In Photon & Proton Beams For Use In Anthropomorphic Phantoms
… assurance program for protons, and for remote anthropomorphic phantom irradiations. The OSLDs used were aluminum oxide (Al2O3:C) nanoDots from Landauer, Inc. (Glenwood, Ill.) measuring 10x10x2 mm3. A square, 20(L)x20(W)x0.5(H) cm3 piece of solid water was fabricated with pockets to allow OSLDs …

Development and Implementation of A Homogeneous and A Heterogeneous Anthropomorphic End to End Quality Assurance Audit System Phantom For Magnetic Resonance Guided Radiotherapy Modalities Ranging From 0.35 T to 1.50 T
… During the credentialing test, end-to-end phantoms are used to evaluate the institution’s ability to perform consistent and accurate radiation treatments. IROC-Houston’s conventional anthropomorphic phantoms are not visible in MR, thus they are insufficient for MRgRT systems. The purpose of …

Benchmarking and Implementation of A New Independent Monte Carlo Dose Calculation Quality Assurance Audit to ol For Clinical Trials
… to measurements made in a water phantom and in anthropomorphic phantoms. Intensity modulated radiation therapy and stereotactic body radiation therapy techniques were used with the anthropomorphic phantoms. Finally, past patient treatment plans were selected and recalculated using DPM and …

A comparative study evaluating the performance of diagnostic radiography units and protocols for paediatric and adult chest radiography examinations
… chest phantom.The CDRAD 2.0 phantom and two anthropomorphic phantoms (adult Lungman and the neonatal Gammex phantom) were used to simulate the chest region. Radiographic acquisitions were conducted on 17 X-ray units located in eight United Kingdom (UK) public hospitals within the North-west …

Effective dose estimation for U.S. Army soldiers undergoing multiple computed tomography scans
… was experimentally verified using two adult anthropomorphic phantoms and optically stimulated luminescent dosimeters. The new method was then compared against a real patient population undergoing similar computed tomography scanning procedures. Utilizing statistical procedures, the new method …

Implementation of An Anthropomorphic Phantom For The Evaluation of Proton Therapy Treatment Procedures
… thermoluminescent dosimeters (TLD) and mailable anthropomorphic phantoms. Currently, there are no heterogeneous phantoms that have been commissioned to evaluate proton therapy. It was hypothesized that an anthropomorphic pelvis phantom can be designed to audit treatment procedures (patient …

Development of A New Independent Monte Carlo Dose Calculation Quality Assurance Audit to ol For Clinical Trials
… based comparison of mock treatment plans in anthropomorphic phantoms. Treatment plans included intensity modulated radiation therapy and stereotactic body radiation therapy techniques. Past phantom treatment plans submitted through a remote auditing program were recalculated using the tool …

CONE BEAM COMPUTED TOMOGRAPHY (CBCT) DOSIMETRY: MEASUREMENTS AND MONTE CARLO SIMULATIONS
… the cone beam CTDI (CTDI<sub>CB</sub>) in CT phantoms and organ dose in a 5-year-old pediatric anthropomorphic phantom. Radiochromic film was also employed to measure the axial dose profiles. A point dose method was used in the CTDI estimation.</p> <p>The BEAMnrc/EGSnrc MC system was used to …

Radiation Dose Estimation for Pediatric Patients Undergoing Cardiac Catheterization
… high-sensitivity MOSFET dosimeters placed in anthropomorphic pediatric phantoms. </p><p>First, the three-dimensional angular dependence of MOSFET detectors in scatter medium under fluoroscopic irradiation was characterized. A custom-made spherical scatter phantom was used to measure response …

Development of A Remote Dosimetric Audit Framework For Carbon Therapy
… and combine these tools to create an end-to-end anthropomorphic phantom audit. The absorbed dose corrections factors for TLD and OSLD will be characterized in a therapeutic carbon beam, as will a variety of plastics typically used in phantom dose measurements. An anthropomorphic phantom, …
