    • C-arm-based surgical data visualization and repositioning using augmented reality 

      Song, Tianyu; 0000-0002-8428-9651 (Johns Hopkins UniversityUSA, 2019-05-02)
      Purpose: As the trend towards minimally invasive and percutaneous interventions continues, the importance of appropriate surgical data visualization becomes more evident. Ineffective interventional data display techniques ...
    • Extension twinning during dynamic compression of polycrystalline magnesium 

      Hustedt, Caleb (Johns Hopkins UniversityUSA, 2016-11-29)
      We performed time-resolved x-ray diffraction on bulk, equal-channel angular extruded (ECAE) polycrystalline magnesium and magnesium alloy AZ31B during dynamic compressive loading at strain rates up to 2500 s−1 at the Cornell ...
    • Interventional 2D/3D Registration with Contextual Pose Update 

      Gu, Wenhao; 0000-0002-5898-9646 (Johns Hopkins UniversityUSA, 2019-05-06)
      Traditional intensity-based 2D/3D registration requires near-perfect initialization in order for image similarity metrics to yield meaningful gradient updates of X-ray pose. They depend on image appearance rather than ...
