Description

Further development of quantitative diagnostic procedures will enhance the selection and implementation of specific therapies that can reduce the damage to the heart muscle when applied to the victims of a heart attack. Ultrasonic imaging is one modality that provides real-time images of the beating heart that may be useful in forming diagnoses and evaluating therapies applied as well as providing insight into the underlying physiology. In characterizing the state of the cardiac muscle after a heart attack a clinician would like the ability to differentiate a segment of myocardial tissue with an old infarct (scarred tissue) from a region with acute ischemic injury where the muscle tissue may still be viable and could potentially be salvaged with the application of an appropriate therapy. Furthermore, once a specific therapy has been applied, it may be useful to monitor the reperfusion of the affected myocardial region. Our goal in ultrasonic tissue characterization is to provide an assessment of the state of the tissue based on quantitative analyses of the ultrasonic signal returned from a specific region of tissue. Implementation of quantitative ultrasonic tissue characterization procedures will complement conventional ultrasonic imaging which provides information regarding the dimensions and motion of the heart.
