Videodensitometry for measuring blood vessel diameter

Acta Radiol Diagn (Stockh). 1980;21(2A):155-64. doi: 10.1177/028418518002102a04.

Abstract

A method employing a special computer for determining the internal diameters of blood vessels from photofluorographic image is described; in vitro and in vivo experiments are performed with the system. The amount of contrast medium injected is restricted to 4 times 3 ml, and it is possible to determine the diameter (in the range from 2 to 16 mm) at any place where blood vessels can be catheterized. In the in vivo experiments the maximum systematic error is +/-5 percent in the 7 to 8 mm range.
