A Nonparametric Approach for Estimating Three-Dimensional Fiber Orientation Distribution Functions (ODFs) in Fibrous Materials

Autor: Lucas H. Timmins, Ross T. Whitaker, Jeffrey A. Weiss, Adam Rauff

Publikováno v: IEEE Trans Med Imaging

Many biological tissues contain an underlying fibrous microstructure that is optimized to suit a physiological function. The fiber architecture dictates physical characteristics such as stiffness, diffusivity, and electrical conduction. Abnormal devi

Using Convolutional Neural Networks to Derive Neighborhood Built Environments from Google Street View Images and Examine Their Associations with Health Outcomes

Autor: Xiaohe Yue, Anne Antonietti, Mitra Alirezaei, Tolga Tasdizen, Dapeng Li, Leah Nguyen, Heran Mane, Abby Sun, Ming Hu, Ross T. Whitaker, Quynh C. Nguyen

Publikováno v: International Journal of Environmental Research and Public Health; Volume 19; Issue 19; Pages: 12095

Built environment neighborhood characteristics are difficult to measure and assess on a large scale. Consequently, there is a lack of sufficient data that can help us investigate neighborhood characteristics as structural determinants of health on a

Infinite ShapeOdds: Nonparametric Bayesian Models for Shape Representations

Autor: Shandian Zhe, Ross T. Whitaker, Wei Xing, Robert M. Kirby, Shireen Y. Elhabian

Publikováno v: AAAI

Learning compact representations for shapes (binary images) is important for many applications. Although neural network models are very powerful, they usually involve many parameters, require substantial tuning efforts and easily overfit small datase

Prediction of femoral head coverage from articulated statistical shape models of patients with developmental dysplasia of the hip

Autor: Penny R. Atkins, Christopher L. Peters, Shireen Y. Elhabian, Andrew E. Anderson, Kunihiko Tokunaga, Praful Agrawal, Keisuke Uemura, Ross T. Whitaker, Joseph D Mozingo

Publikováno v: Journal of orthopaedic research : official publication of the Orthopaedic Research Society. 40(9)

Developmental dysplasia of the hip (DDH) is commonly described as reduced femoral head coverage due to anterolateral acetabular deficiency. Although reduced coverage is the defining trait of DDH, more subtle and localized anatomic features of the joi

Publikováno v: International Journal of Computer Assisted Radiology and Surgery. 14:1955-1967

We propose a segmentation methodology for brainstem cranial nerves using statistical shape model (SSM)-based deformable 3D contours from T2 MR images. We create shape models for ten pairs of cranial nerves. High-resolution T2 MR images are segmented
