    • Algorithms for Automated Pointing of Cardiac Imaging Catheters 

      Loschak, Paul; Brattain, Laura; Howe, Robert D. (Springer Science + Business Media, 2014)
      This paper presents a modified controller and expanded algorithms for automatically positioning cardiac ultrasound imaging catheters within the heart to improve treatment of cardiac arrhythmias such as atrial fibrillation. ...
    • Automated pointing of cardiac imaging catheters 

      Loschak, Paul; Brattain, Laura; Howe, Robert D. (2013)
      Intracardiac echocardiography (ICE) catheters enable high-quality ultrasound imaging within the heart, but their use in guiding procedures is limited due to the difficulty of manually pointing them at structures of interest. ...
    • Enhanced Ultrasound Visualization for Procedure Guidance 

      Brattain, Laura (2014-06-06)
      Intra-cardiac procedures often involve fast-moving anatomic structures with large spatial extent and high geometrical complexity. Real-time visualization of the moving structures and instrument-tissue contact is crucial ...
    • Instrument Tracking and Visualization for Ultrasound Catheter Guided Procedures 

      Brattain, Laura; Loschak, Paul; Tschabrunn, Cory Michael; Anter, Elad; Howe, Robert D. (Springer Science + Business Media, 2014)
      We present an instrument tracking and visualization system for intra-cardiac ultrasound catheter guided procedures, enabled through the robotic control of ultrasound catheters. Our system allows for rapid acquisition of ...
    • Real-Time 4D Ultrasound Mosaicing and Visualization 

      Brattain, Laura; Howe, Robert D. (Springer Science + Business Media, 2011)
      Intra-cardiac 3D ultrasound imaging has enabled new minimally invasive procedures. Its narrow field of view, however, limits its efficacy in guiding beating heart procedures where geometrically complex and spatially extended ...
