Soft tissue examination apparatus and method employ an ultrasonic transducer system for generating a series of ultrasound pulses, at least one of which is of sufficiently high intensity to induce physical displacement of the soft tissue. The transducer receives a series of ultrasonic echo pulses and responsively generates a series of data signals indicative of such tissue displacement. A data processor receives the data signals and determines the magnitude of the displacement. In such a manner, the present invention assists in the evaluation and/or diagnosis of biological tissue. Preferably, the apparatus and method of this invention is employed to examine the properties of a subject's vitreous body and thus may be used in the evaluation and/or diagnosis of ocular disorders, such as vitreous traction. |
