Contrast injector for injecting a contrast medium to generate prolonged uniform vascular enhancement

摘要: A contrast medium injector (20) for injecting a patient with CT scan is programmed to provide an injection protocol that representation of ideally defined exponential curve initial rate decaying at rate. This has been found produce uniform vascular enhancement the scanning patient's blood vessels. The particular decay coefficient which be optimal directly proportional cardiac output divided by weight, and approximated 0.01 typical human.
