Abstract :
A new interface for high resolution online digitization of unprocessed radiofrequency signals was developed. Preliminary clinical data suggest that, based on measurements of end-diastolic integrated ultrasonic backscatter, this new device permits the noninvasive recognition and monitoring of acute cardiac allograft rejection in transplant patients
