SYSTEM AND METHOD FOR ULTRASONIC HARMONIC IMAGING FOR THERAPY GUIDANCE AND MONITORING |
摘要 |
An ultrasound system is provided which includes a therapy ultrasound transducer and a diagnostic ultrasound transducer and operates in accordance with a method to direct the application of the therapy ultrasound. The method includes operating the diagnostic ultrasound transducer to acquire a first ultrasound image; simultaneously operating the diagnostic ultrasound transducer and therapy ultrasound transducer for a second interval to acquire a second ultrasound image; and determining a difference in the first and second images indicative of the pattern of the therapy ultrasound transducer signal. The difference in the images, which result from enhanced non-linearities and propagation distortions induced by the high intensity therapy ultrasound, can be obtained by subtracting the two images. A method is also provided for monitoring the progress of high intensity therapy ultrasound which evaluates transient changes due to in-situ heating as well as permanent changes which result from cell microstructure alteration.
