摘要： An auscultation system includes a transducer for generating an acoustic signal at a transducing location of the subject, and a sensor for receiving an attenuated acoustic signal at a sensing location of the subject. The attenuated signal received at the sensing location is digitized, and may be analyzed in the frequency and/or time domain. The comparison of the digitized attenuated signal against the initial transduced signal allows for the computation of the degree of acoustic attenuation between the transducing and sensing locations. Acoustic attenuation may be utilized to generate an intensity ratio. The ejection fraction of the heart subject may then be computed by correlation to the intensity ratio. Pulse echo methods are also disclosed. The echo transducer is oriented on the subject and generates a series of signal pulses. The return echo on the pulse is then received and a brightness encoded image is produced. The return echo provides location data on the internal structures of the subject including location, motion and speed.
