Abstract
A method for profiling an infusion of a medicament into the wall of an artery involves inserting an intravascular ultrasound device into the artery and advancing it to the location of the infusion. A pullback device withdraws the intravascular ultrasound device from the artery, pausing at predetermined axial sites along the location of the infiltrated medicament to image the infusion profile at each site. A computer then compiles the individual site profiles to produce three dimensional images indicating the extent of infiltration of the medicament into the tissue surrounding the artery.
