BEYOND THE DVH --SPATIAL AND BIOLOGICAL RADIOTHERAPY TREATMENT PLANNING by BO ZHAO August 2010 Advisor: Dr. Jay Burmeister Co-Advisor: Dr. Michael C. Joiner Major: Medical Physics Degree: Doctor of Philosophy Purpose: Both spatial and biological information are necessary in order to perform true optimization of a treatment plan and for predicting clinical outcome. The goal of this work is to de...

background: to reduce the dose to normal tissues surrounding the treated breast, a uniform magnetic field was used within a humanoid phantom in breast radiotherapy. materials and methods: monte carlo simulations were performed with geant4, irradiating humanoid phantoms in a magnetic field. to reconstruct phantoms, computed tomography (ct) data slices of four patients were used for the monte car...

Purpose (Chemo)–radiotherapy (RT) is the gold standard treatment for patients with locally advanced lung cancer non accessible surgery. However, current toxicity prediction models rely on clinical and dose volume histograms (DVHs) remain unsufficient. The goal of this work to investigate added predictive value radiomics approach applied maps regarding acute late toxicities in both lungs esophag...

Sensory Substitution Devices (SSDs) assist Visually Impaired People (VIP) by providing information usually acquired vision through another functional sensory modality. Here, we evaluate a SSD that aims to guide visually impaired people target converting spatial into sound. A balance must be struck between parsimonious and explicit guidance, so it is precise but not imposing an excessive cogniti...

Technological literacy is essential for students learning in an educational environment that is increasingly emphasising the use of technology. This paper reports on a number of issues involved in the embedding of technological literacy at an institutional, faculty and individual level. At the Queensland University of Technology (QUT), an integrated approach to the acquisition of technological ...
