Three-Dimensional Dynamic Imaging of the Heart, Lungs, and Circulation by Roentgen-Video Computed Tomography

  • R. A. Robb


It is of fundamental importance in studies of cardiovascular and pulmonary physiology and for obtaining more accurate clinical assessments of regional heart, lung, and circulatory function to measure and analyze the dynamic regional changes in geometry, perfusion and tension of these organ systems. As described by Mitchell and Mullins (1967) and by Wood et al. (1972), the function and performance of the heart, lungs and circulation are inseparably linked to their motion in three dimensions. However, satisfactory noninvasive methods have not as yet been established for the determination of the true, dynamic changes in shape and dimensions of the intact heart and lungs or for accurate three-dimensional measurement of the distribution of blood flow to, from, and within these and other organ systems of the body. Such measurements are required for accurate quantitative studies of the structure and function of these organ systems to be carried out.
