Analysis of edge-tracking errors inherent in fluoroscopic images of the beating heart.

Abstract

RATIONALE AND OBJECTIVES Because of the complex relationships between the dynamic three-dimensional cardiac surface shape and its projected image, errors arise with the use of two-dimensional silhouettes to measure displacements of the heart. The character and frequency of such errors are examined. METHODS A high-precision x-ray scatter imaging technique… (More)
