Does Breathing Motion Change Weeks to Years after Treatment?
A CT-simulation approach has been developed which images free breathing patients with lung tumors by generating a motion model that is a function of breathing amplitude and rate (5DCT). Of the >300 patients simulated with 5DCT, 13 have been simulated more tha...

Head and Neck Gross Tumor Volume Deep-Learning Autocontouring Model Using Bigroc Collaborative Data
Accurate delineation of Head and Neck (H&N) Gross Tumor Volumes (GTV) is a prerequisite for effective radiotherapy, represents a significant cognitive challenge, and may contribute to an observed outcomes deficit between high-volume and low-volume H&N radioth...

Infrastructure for Building a Population-Level Atlas of the Spatial Distribution of Lung Nodules Using the National Lung Screening Trial Dataset
Lung nodule distribution is non-homogeneous, yet localized risk factors are poorly understood. This study aims to develop a computational pipeline to construct a 3D lung atlas, identifying population-level spatial trends to guide clinical diagnosis and treatm...

Predicting Survival In Head and Neck Cancer: The Protective Role of BMI and the Impact of Evolving Soft Tissue Volumes during Radiotherapy
The nutritional status of head and neck cancer (HNC) patients receiving radiotherapy often declines due to treatment-related side effects. This study characterizes the effect of baseline body mass index (BMI) on overall survival and analyzes how soft tissue v...
