Speed of response of a 50 Hz and a 250 Hz TV system
Acta Radiologica: Diagnosis
|July 1, 1975
Abstract:
The speed of response of a newly developed 250 Hz high image rate Plumbicon television system was compared with the ordinary 50 Hz Vidicon and Plumbicon television systems. The high time resolution of the 250 Hz system, almost five times that of the 50 Hz Vidicon and three times that of the 50 Hz Plumbicon system, makes it well adapted for videodensitometry particularly if the velocity of the contrast bolus or the pulse profile within the circulation are to be evaluated.
