Abstract

A contrast effect measuring unit (104) measures the contrast effect of an ultrasound contrast agent in a patient (110). The control unit (106) determines a desired contrast agent infusion rate, based on the contrast effect measured by the contrast effect measuring unit (104) and programmed contrast effect parameters. The control unit (106) controls an infusion unit (102) to infuse the patient (110) with the determined infusion rate. An ultrasound imaging unit (108) performs an ultrasound imaging test on the patient (110). This process is continued through the course of the ultrasound imaging test, to maintain a steady contrast effect and a steady signal enhancement level for the patient (110).
