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.
描述了一种使用特殊计算机从荧光摄影图像确定血管内径的方法；用该系统进行了体外和体内实验。注入的造影剂用量限制为4×3毫升，并且可以在任何能够插入导管的血管部位确定直径（范围为2至16毫米）。在体内实验中，在7至8毫米范围内最大系统误差为±5%。
