Since the discovery of X-rays in 1895 by Conrad Rontgen, progress in the
technical field has more or less kept pace with advancement in clinical
One aspect of radiology, however, lagged behind the enormous progress
in technology, namely the applied physiology. Diagnostic radiology has to a
large extent concentrated on static documentation of physiological and
pathological processes, while facilities for documentation of flow patterns are
being made available to an increasing extent.
A vast scope for research, teaching, and detecting incipient pathological
processes is afforded by using techniques where the actual processes are
recorded and stored by means of e.g. video tapes and cine radiology.
By correlating live radiology with clinical data, the changes indicative of
early or incipient pathology can be observed and stored for reference in a
library to supplement the standard film "museums" of teaching hospitals.
