Multiple Path Particle Dosimetry For Prediction Of Mouse Lung Deposition Of Nanoaerosol Particles, Mohammed Ali
Multiple Path Particle Dosimetry For Prediction Of Mouse Lung Deposition Of Nanoaerosol Particles, Mohammed Ali
Mohammed Ali
Nanoaerosolized particle (dia.<200 >nm) antibiotic inhalation therapy was tested to treat pneumonic tularemia in mice caused by Francisella novicida infection. Very limited experimental techniques are available to properly estimate inhaled doses and distribution of the drug inside the mouse lungs. To overcome this problem, computational simulation of particle deposition based on the Multiple Path Particle Dosimetry (MPPD) model was employed to simulate in vivo experimental conditions which included nasal breathing with whole body exposure to the antibiotic in the form of nano-aerosolized medicine. The deposition results were compared with several in vivo experimental data reported in literature; and satisfactory agreements …
Using The Theory Of Planned Behavior As A Predictor Of Radiologic Technologists' Use Of Patient Radiation Protection Best Practices: A Regional Study, Brenda L. Boyd
Brenda Boyd, PhD
Problem. A growing concern exists that patients are receiving an increase in radiation exposure while undergoing medical imaging exams. According to a March 2009 report by the National Council on Radiation Protection and Measurements (NCRP), the U.S. population's total exposure to ionizing radiation has nearly doubled over the past two decades. With the introduction of new digital radiology equipment, patient dose is on the rise. Possible reasons for a radiologic technologist's behavior include: influence by availability or lack of equipment, policies, social pressure, attitudes, and a safety culture. Little research has been done in this area, specifically with applying a …
