    • Enhancing imaging systems using transformation optics. 

      Kundtz, NB; Landy, Nathan I; Smith, David R; Urzhumov, Yaroslav A (Opt Express, 2010-09-27)
      We apply the transformation optical technique to modify or improve conventional refractive and gradient index optical imaging devices. In particular, when it is known that a detector will terminate the paths of rays over ...
    • Improving the lens design and performance of a contemporary electromagnetic shock wave lithotripter. 

      Fovargue, DE; Kuntz, NJ; Lipkin, ME; Madden, JF; Mitran, S; Neisius, A; Preminger, GM; ... (11 authors) (Proc Natl Acad Sci U S A, 2014-04-01)
      The efficiency of shock wave lithotripsy (SWL), a noninvasive first-line therapy for millions of nephrolithiasis patients, has not improved substantially in the past two decades, especially in regard to stone clearance. ...
    • Optical-CT 3D Dosimetry Using Fresnel Lenses with Minimal Refractive-Index Matching Fluid. 

      Adamovics, J; Bache, S; Malcolm, J; Oldham, Mark (PLoS One, 2016)
      Telecentric optical computed tomography (optical-CT) is a state-of-the-art method for visualizing and quantifying 3-dimensional dose distributions in radiochromic dosimeters. In this work a prototype telecentric system (DFOS-Duke ...
