Abstract :
Modifications were made to a commercial ultrasound scanner to improve established myocardial perfusion estimation methods. These modified methods were tested in a series of animal experiments where the coronary flow was controlled. The measured flow was related to perfusion parameters determined through ultrasonic imaging
