[Initial clinical experiences with the fast digital picture of roentgen transmission profiles in the human (the chronogram)].
By means of suitable hardware and software changes it becomes possible to obtain transmission profiles of high time resolution (up to 50 profiles/sec) with the help of a CT device which is suitable for the recording of digital radiographs, in one transversal body layer. In this manner, it becomes possible to measure changes in the density profile from 6 up to 50 sec and to analyse them. This method called "Chronogram", enables high-resolution recording of density changes, similar to kymography. The possibilities of using contrast media are demonstrated by means of phantom measurements, and initial clinical experiences are outlined on the basis of practical examples.
