| Prof. Jeff Fessler and his research group earned three poster awards at the 2007 SPIE (The International Society for Optical Engineering) Medical Imaging Conference, held Feb. 17-22, 2007. The winning posters: "A simplified motion model for estimating respiratory motion from orbiting views," by R Zeng, J A Fessler, and J M Balter. Cum laude poster award "Local mismatch location and spatial scale detection in image registration," by R Narayanan, J A Fessler, B Ma, C R Meyer. Honorable mention poster award "Fast variance predictions for 3D cone-beam CT with quadratic regularization," by Y Zhang-O'Connor, J A Fessler. Honorable mention poster award Rongping Zeng and Yingying Zhang-O'Connor are graduate students in EE: Systems. Ramkrishnan Narayanan earned his MS in EE:Systems, and recently completed his PhD in biomedical engineering under Prof. Fessler and Prof. Meyer. Also collaborating in the research are Prof. James Balter, Radiation Oncology, and Prof. Charles Meyer and Dr. Bing Ma, Digital Image Processing Lab, Dept. of Radiology. Prof. Fessler's research interests include medical imaging, tomography, nonparametric estimation, and inverse problems, with current projects in PET, SPECT, X-ray CT, MRI, radiation therapy, and image registration. He is interested both in developing algorithms for these problems, as well as analyzing and predicting the properties of these algorithms. |
