Advancement of A 3D Computational Phantom and Its Age Scaling Methodologies For Retrospective Dose Reconstruction Studies
<p>We have used a 3D age-scalable computational phantom for over two decades for retrospective dose reconstruction studies of childhood cancer survivors (CCS) treated with 2D historic radiotherapy (RT). However, our phantom and its age scaling functions (ASF) must be updated so that it can be used …

Assessment of imaging dose from the kilovoltage cone beam computed tomography system on board the Varian Halcyon linear accelerator
… Crossline profiles to those measured in a water phantom using calibrated parallel plate and thimble ionisation chambers. In-phantom dose measurements using Radiochromic film in RANDO pelvic and thoracic phantoms were used to generate a Normalisation Factor to relate the measured and simulated …

A comparison of three computational phantoms for calibration of a radiation portal monitor used for measurement of internal contamination.
… (personnel) measurement time. Three different computational phantoms were considered for this work: the adult male Bottle Mannequin Absorber (BOMAB) phantom, the University of Florida – Oak Ridge National Laboratories (UF-ORNL) stylized phantom, and the International Commission on Radiological …

Risk and Risk Factors For Colorectal Subsequent Malignancies In Survivors of Childhood Cancer: A Report From The Childhood Cancer Survivor Study
<p>Survivors of childhood cancer are at risk for colorectal subsequent malignant neoplasms (SMNs); notably, these cancers are amenable to screening. To identify at-risk survivors that may benefit from early screening, descriptive and risk factor analyses were performed to ascertain risk factors for …

Infrastructure Development For Personalized Risk Prediction to Reduce Cardiovascular Disease In Childhood Cancer Survivors
… dosimetry from reconstructing survivors’ RT on computational phantoms with a simple heart model.</p> <p>Thus, the main objective of this research was to expand the dose reconstruction infrastructure for late effects studies and enhance the heart model to improve the accuracy of whole heart …
