Accuracy of Planar Dosimetry for Volumetric Modulated Arc Therapy Quality Assurance
(2011)With the advent of new, more efficient, rotational therapy techniques such as volumetric modulated arc therapy (VMAT), radiation therapy treatment precision requires evolving quality assurance. Two dimensional (2D) detector ... -
Design and Implementation of an Institution-Wide Patient-Specific Radiation Dose Monitoring Program for Computed Tomography, Digital Radiography, and Nuclear Medicine
(2011)Recently, there has been renewed interest in decreasing radiation dose to patients from diagnostic imaging procedures. So far, efforts to decrease radiation dose have focused on the amount of radiation delivered from typical ... -
Diffusion Tensor Imaging of Myelin Water
(2011)In recent years, the emergence of diffusion tensor imaging (DTI) has provided a unique means via water diffusional characteristics to investigate the white matter integrity in the human brain, and its impact on neuronal ... -
Estimating Effective Dose from Phantom Dose Measurements in Atrial Fibrillation Ablation Procedures and Comparison of MOSFET and TLD Detectors in a Small Animal Dosimetry Setting
(2011)Atrial Fibrillation (AF) is an ever increasing health risk in the United States. The most common type of cardiac arrhythmia, AF is associated with increased mortality and ischemic cerebrovascular events. Managing AF can ... -
Parameterizing Image Quality of TOF versus Non-TOF PET as a Function of Body Size
(2011)Positron emission tomography (PET) is a nuclear medicine diagnostic imaging exam of metabolic processes in the body. Radiotracers, which consist of positron emitting radioisotopes and a molecular probe, are introduced into ... -
Time-of-Flight PET Compared to Increased Scan Time in Low-Contrast Regions
(2011)Positron Emission Tomography is a coincidence-detection-based nuclear imaging modality that has increased in clinical prevalence over the last two decades. Measures have recently been taken to improve the practice, specifically ...
