An early automatic computer system can process left ventricular cineangiocardiograms to calculate volume-time curves, though algorithm improvements are needed for clinical application.
Early LV cineangiocardiogram automation offers rapid processing but needs edge-detection refinement; leaves open clinical applicability pending validation.
An automatic computer system has been developed and programmed to scan raw, unaltered, left ventricular cineangiocardiograms and calculate the volume of each frame by an integration method. The resulting volume-time curves can be displayed on demand. Each frame is processed in about three seconds and the next frame automatically advanced. The system works well on an experimental basis, but improvements must be made in the edge-following algorithms before clinical material can be processed routinely.
