• 3D Visualization of Pose Determination: Application to SPECT Imaging 

      Mullick, Rakesh; Ezquerra, Norberto F.; Garcia, Ernest Victor; Cooke, C. David; Folks, R. D. (Georgia Institute of Technology, 1993)
      Pose determination of 3D objects is a topic of active research, particularly in the area of medical imaging. The determination of the pose or orientation of a 3D object in a 3D dataset can be viewed as a two-fold problem: ...

    • Automated Segmentation of Coronary Vessels in Angiographic Image Sequences Utilizing Temporal, Spatial and Structural Constraints 

      O'Brien, James F.; Ezquerra, Norberto F. (Georgia Institute of Technology, 1994)
      The methods presented here have been developed to perform the automated segmentation of coronary arterial structure from cine sequences of biplanar x-ray angiograms. We introduce a methodology to impose an integrated set ...
    • Automatic Segmentation of 3D Cardiac SPECT Imagery 

      Mullick, Rakesh; Ezquerra, Norberto F. (Georgia Institute of Technology, 1993)
      The automatic visualization and quantitative analysis of cardiac SPECT data requires the ability to automatically segment and extract voxels representing the heart. The attributes of the 3D data make this task quite ...
    • A method for interactive manipulation and animation of volumetric data 

      Jean, Yves Darly; Hodges, Larry F.; Pettigrew, Roderic (Georgia Institute of Technology, 1991)
      We outline an efficient method for visualizing and manipulating volumetric data, in particular, cardiac MRIdata sets. The approach is designed to allow interactive manipulation and real-time animation of volumetric data ...
    • A Neural Network Approach to Assess Myocardial Infarction 

      Pazos, Alejandro; Maojo, Victor; Martin, Fernando; Ezquerra, Norberto F. (Georgia Institute of Technology, 1991)
      The assessment of myocardial infarction is a complex information intensive process that involves the analysis and interpretation of cardiovascular nuclear medicine images. For a number of years, a knowledge-based approach ...
