A video-angiometer for simultaneous and continuous measurement of inner and outer vessel diameters. Technical report.

R Assmann, H Henrich.   

Abstract

A system is described for continuously measuring vessel diameters. It bases on the evaluation of video signal differences of a video camera which are induced by light intensity differences (grey levels) caused by the vascular wall structures. The system is electronically linear, automatically measuring and in addition eyeball controlled by the human sensor: the inaccuracy does not exceed the 5% level.
