Abstract :
During the past decade, closed-circuit television has become an important means of displaying images in medicine. Important concurrent physiological signals in analog form are not readily displayed simultaneously with images using standard television systems. This communication describes a moving-trace design which superimposes analog traces on video images. Investigators can thereby directly visualize and evaluate relationships between images and dynamic physiologic variables.
