Research Mission

The 3D and Quantitative Imaging Laboratory is dedicated to exploring and developing innovative visualization and post-processing techniques of medical imaging to aid in the quantitative assessment and analysis of disease diagnosis, treatment planning and treatment evaluation. 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

Individual Risk Prediction After TAVR

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.

3D Printing Anatomical Models

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.
