Abstract :
For sequential perfusion measurements in several image planes with replenishment method, we propose a fast technique by consecutively scanning respective image planes twice: Firstly using only a short period of imaging pulses after micro- bubble destruction to assess slope and secondly using few imaging pulses to assess final value. Both scans are combined to extract perfusion rate and blood volume.
