We strive to apply the most advanced image processing technologies and systems to maximize the diagnostic information obtained from each imaging study to ensure clinicians provide excellent care for our patients.

Our research endeavors include developing unique post-processing protocols, spearheading interdisciplinary clinical programs, and implementing emerging technologies to help visualize the most complex of cases. Such work is possible only through close collaborations between the Department of Radiology and clinicians from other specialties, including cardiothoracic surgery, neurology, oncology, and pediatrics, as well as faculty and researchers from other school, outside institutions, and industry.

Research projects range from developing new post processing protocols for clinicians within the Department of Radiology and other specialties in the Department of Medicine, spearheading interdisciplinary programs to optimize patient care, and implementing new visualization technologies for
complex cases.

Current Research & Projects

[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_hoverbox image=”6087″ primary_title=”” hover_title=”Individual Risk Prediction After TAVR” shape=”square”]

Adequate risk characterization is essential in patients undergoing transcatheter aortic valve replacement (TAVR). The goal of this project is to evaluate potential risk predictors in patients. Together with the departments of Cardiology and Cardio-thoracic Surgery we built a database with over 400 patients. Currently, we are evaluating CT measurements for sarcopenia and frailty, and we are evaluating the prognostic value of calcifications of the cardiac valves and coronary arteries.

[/vc_hoverbox][/vc_column][vc_column width=”1/2″][vc_hoverbox image=”6083″ primary_title=”” hover_title=”3D Printed Anatomical Models” shape=”square”]

The 3DQ Lab uses additive manufacturing technologies to generate three-dimensional anatomical models that demonstrate areas of a patient’s body. Our lab provides a variety of 3D printing modalities such as FDM, SLA, and DLP; with materials spanning opaque ABS to semi-transparent photopolymers. We utilize  DICOM data to reproduce patient-specific anatomy that can be used for education, pre-surgical planning, and patient consent. 3D Print orders can currently be placed through EPIC.

[/vc_hoverbox][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_hoverbox image=”6091″ primary_title=”” hover_title=”Tumor Response Assessment by Criteria” shape=”square”]

Standardized reporting and visualization of lesion size over the course of cancer treatment provides oncologists with consistent, reliable information for treatment decisions and gives patients and intuitive visualization of the disease process (via tables and diagrams). This data serves as a scientific database for deeper analysis of the imaging time points, disease development under various therapeutic approaches, and application of alternate criteria standards for prediction of patient outcomes.

[/vc_hoverbox][/vc_column][vc_column width=”1/2″][vc_hoverbox image=”6101″ primary_title=”” hover_title=”3DQ Lab Aortic Surveillance” shape=”square”]

Patients with aortic diseases require life-long surveillance with imaging to detect and prevent catastrophic outcomes, such as aneurysm formation and rupture. Surgical decisions are based on sizes at various locations of the aorta and the growth rate. Identifying and measuring the exact locations along the aorta between cohorts of patients is challenging but can be addressed through standardized measurement locations. Communicating this information is possible with our database and custom graphing tools.

[/vc_hoverbox][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_hoverbox image=”6109″ primary_title=”” hover_title=”Computational Fluid Dynamics” shape=”square”]

The 3DQ Lab performs computational fluid dynamic simulations of patient-specific aortic dissections. In collaboration with the Marsden Lab, we utilize Fluid-Structure-Interaction methods on Arbitrary-Eulerian-Lagrangian meshes to obtain realistic pressure and velocity information in patient-specific models. Learning about the interaction of deformation, wall shear stress, pressure differences, and oscillatory shear stress assists with understanding the driving factors in disease progression.
