Robust Optimization for Empty Repositioning Problems

This paper develops a robust optimization framework for dynamic empty repositioning problems modeled using time-expanded networks. In such problems, uncertainty arises primarily from forecasts of future supplies and demands for assets at different time epochs. The approach developed in this paper models such uncertainty using intervals about nominal forecast values and a single control paramete...

T4DT: Processing 4D CT scans of the Lungs

A proposal submitted to 2005 GC4R program for Collaborative Advances in Biomedical Computing (C-ABC) Project Summary: We propose to develop information technology for processing time-varying CT scans (4D CT) of the lungs. In particular, we propose to develop tools for estimating the ventilation (air flow) and perfusion (blood flow) from 4D CT and apply these tools to quantitatively assess the e...

Motion artifacts occurring at the lung/diaphragm interface using 4D CT attenuation correction of 4D PET scans

For PET/CT, fast CT acquisition time can lead to errors in attenuation correction, particularly at the lung/diaphragm interface. Gated 4D PET can reduce motion artifacts, though residual artifacts may persist depending on the CT dataset used for attenuation correction. We performed phantom studies to evaluate 4D PET images of targets near a density interface using three different methods for at...

Immunotherapeutic strategies for bladder cancer

Bladder cancer is a common urologic malignancy with rising incidence in the elderly population. In most cases, bladder cancer is non-muscle-invasive at diagnosis and shows dramatically high recurrence rates, although current treatments often reduce the risk of disease progression. Immunotherapy using intravesical instillation of Bacillus Calmette-Guérin (BCG) remains the most effective therapy ...

SU-E-T-565: Effectiveness of Robust Optimization in Head and Neck IMPT Dose Distributions.

PURPOSE The effectiveness of IMPT may be significantly diminished by range and patient setup uncertainties. The purpose of this presentation is to evaluate the ability of robust optimization methods to desensitize H&N IMPT plans to uncertainties and their impact on plan optimality. METHODS We use a robust optimization method, in which the objective function value for a given iteration is comp...
