xREZ lab director Ruth West is collaborating with Prof. Cindy Grimm, Oregon State University, and Prof. Tao Ju at Washington University St. Louis in research to understand what human beings see, think and do as they navigate 3D/4D volume data, such as MRI or CT imaging and segment it during the process of its interpretation. The goal of this collaboration is to develop a set of design principles and algorithms that will help in developing better tools to improve the accuracy, repeatability, and efficiency of the segmentation process and enhance the quality of segmentation data in a variety of applications including biomedicine, clinical practice and environmental engineering. This work is supported by NSF Collaborative: Developing Conceptual Models for Navigation, Marking and Inspection in the Context of 3D Image Segmentation, IIS-1302248, IIS-1302142, IIS-1302200.
