Three-dimensional reconstruction of the human heart by video technique.
Three-dimensional reconstruction of different plastic phantoms, organic material and beating human heart was achieved by utilizing a standard roentgen-television system. In continuous stabilized fluoroscopy the television images of the object obtained from different projections were digitized in real time and computerized for reconstruction. Despite a cone beam being used, the spatial resolution seems to be quite adequate for evaluation of gross anatomic structures like the cardiac walls without enhancement by contrast medium.
