DEVICE FOR INJECTING CONTRAST MEDIUM INTO BLOOD VESSEL

摘要

PROBLEM TO BE SOLVED: To provide a new device for injecting the contrast medium into a blood vessel.

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